Some Medical Hypotheses

Many people in medical fields accumulate these points of curiosity that are outside their specialization or that they otherwise never have time to follow up on. Here are several. As always, nothing here should be taken as medical advice.
  1. The decline in alveolar ventilation with age as measired by DLCO (about 1% a year) results partly from the gradual accumulation of small subclinical pulmonary emboli. This predicts that people on blood thinners should show a slower decline. Also, part of the increased all-cause mortality seen in people who sit a lot relative to those who don't is the result of such emboli, in the lungs and elsewhere, suggesting people who sit less should also show a decreased rate of lung function loss. (This second part of the hypothesis is appealing because you can't undo sitting mortality by adding exercise, just like you can't undo that PE from your flight to JFK by hitting the gym after you get off the plane. Also, frequent sitting is evolutionarily recent, and in fact our ancestors most likely had more exsanguinating traumas than we do, so even without sitting the balance in our current environment is still too tilted toward clotting.) Of note, capillary microthrombi do account for some of the dysfunction in COVID hypoxemia, though I am unaware to what extent this mechanism accounts for persistent hypoxemia in recovered COVID patients (Dhont et al 2020.)

  2. One of the functions of a four-chambered heart is to prevent clots from reaching end organs. In the brains of animals with less dependence on complex behavior and/or without small capillaries, this is less of a problem. True cold blooded modern reptiles do not have small capillaries and have three chambered hearts. Dinosaurs, birds and mammals are all warm blooded or poikilothermic and have four- chambered hearts. A four chambered heart provides an additional aperture that thrombi have to pass through, and for developmental reasons may make it more likely that patent foramen ovale-type defects are less likely.

  3. Mammalian red blood cells are enucleate. The prevailing theory is that mammals have the tiniest capillaries of all orders (even moreso than birds, consistent with being warm blooded). The new hypothesis here is that mammals' on average more communal living makes them more susceptible to viruses. (Yes birds live communally but in terms of physical contact mammals on average spend more time directly touching.) The majority of cells in blood are RBCs. A virus adapted for infecting nucleate RBCs could do quite a bit of damage in animals that had them. But in mammals, these viruses would only enter an empty shell. Note that the next most common type of blood cell, the neutrophil, is programmed to self-destruct in 24 hours, and indeed ejects its nucleus as its main defense, frustrating any pathogen that needs time to do its work and on top of that would have to be adapted to both intra and extracellular conditions. I am not aware of any virus which infects and reproduces using the translational machinery of avian red blood cells but the existence of such viruses would support this theory. In fact RBCs in non-mammalian vertebrates do have active adaptive immunity functions (Nombela and Ortega-Villaizan 2018). That the maturation of red blood cells is directly dependent on ejection of the nucleus suggests this is an important pathway (Testa 2004), which may also be an adaptation for cancer resistance in long-lived species that thusfar only mammals have taken advantage of. Of course many viruses interact with RBCs in mammals, but do not (cannot!) use them to reproduce.

Parasite Burdens and the Flynn Effect

The Flynn Effect is the real, not-test-based increase in IQ seen in first-world countries, about 3 IQ points a decade. In the last couple decades the effect has leveled off in much of developed world. There's a lot of discussion over why this should be.

One obvious candidate is parasite burden. As countries develop, public sanitation gets better, and public health improves. If it's public health (pathogens plus nutrition) and offering standardized schooling to all, you would expect to see an eventual plateau in developed countries, and the developing countries begin to follow their trend.

Any parasite which directly damages the brain is an obvious candidate as one causative agent. This is especially interesting when you read that up to one-third of people in, e.g. Peru, have radiographic evidence of neurocysticerosis - tapeworm damage in the brain. This study shows that of people with evidence of the disease, 18.2% of them in childhood have IQ < 70. Starting to connect dots, we can start making an estimate of IQ improvement from eradication of neurocysticercosis alone.

  • Let's assume that (as the Peruvian study showed) 33% of people have neurocysticerosis.

  • Let's assume that of the people with neurocysticercosis, 18.2% (4% of the total population) have IQ < 70, the mean IQ is 69. This is obviously simple and actually quite conservative, but the higher we make the mean number for this subgroup, the more modest the effect of eradicating neuroscysticercosis.

  • Let's also assume that the 70 and above IQ folks are evenly distributed between 70 and 100. Also simplifying, but I doubt neurocysticercosis makes many people smarter.

  • With those assumptions, then a 3-point IQ increase in the general pouplation could be brought about by a one-third decrease in NC cases.

  • Of course the 3-point IQ trend goes on for more than 3 decades (when all three-thirds of would-be neurocysticercosis patients were prevented from getting it) so it can't just be that.

To test the hypothesis, we could look at average IQ increases going forward in developing countries currently getting de-wormed. You could also look at existing Flynn Effect curves for the developed world and compare it against the % population getting on clean public water supplies. Of course it's hardly controversial that lower parasite burden would correlate with better outcomes, and indeed the de-worming projects have already shown an improvement in school attendance in participating areas. And while parasite diseases cause massive human suffering, this is still interesting even just by purely pragmatic reasons: a country's economic well-being is linked to the average IQ.

Is a Virus Alive?

The pandemic has brought this question much more public attention than usual. It seems to be an interesting question - but on scrutiny, the problem evaporates.

Viruses are replicators. The question of whether they (or anything) is alive is not a useful one.

It boils down to this: in most of these discussions, what we're really asking, when we ask if COVID-19 is "alive", is whether it can make us sick. If it can replicate, it can make us sick, and we know that viruses can replicate. Categorizing things as "alive" turns out to be an arbitrary exercise that neither organizes our knowledge nor adds information - it's much like asking if a submarine swims. What this exposes is that we have no definition of "alive" to begin with. "Alive" is just the label in English for an intuitive category in our animal brains having to do with animacy or agency, and at the molecular level or with non-intuitive strange entities like viruses (or slime-molds, or jellyfish) these intuitions fail us.

More explanation:
  1. Specific to COVID-19, most of them time people ask "Is it alive?" when we're talking about the virus "remaining alive" for certain lengths of time on surfaces. Of course what we really care about is whether it can make you sick. Poison oak oil (urushiol) can cause a Type IV allergic reaction after decades. Is it alive?

  2. "Make you sick" corresponds to "reproduction". Fire, stalagmites, and black holes (if you follow Lee Smolin's argument) all grow and/or reproduce. Why aren't those alive?

  3. You might have rolled your eyes when I mentioned fire, and not been wondering whether that is a living thing. We instinctively recognize there's a distinction, but it's worth spending time on. There IS something qualitatively different between a virus, and fire. Viruses are discrete entities that are alike - with elements ordered in a certain way - despite having been made from those elements when they were NOT so ordered. But fire does not carry historical information in this way. That is to say - if two coworkers get infected with COVID-19, despite being genetically different people with different cells, they will produce identical viruses. You can tell the viruses came from other coronaviruses. In contrast, if you light two identical sticks, one by sticking it in a campfire and the other from a cigarette lighter, it doesn't matter - they will burn the same way. You can't tell where that fire is "descended" from.

  4. Being more specific, viruses and people are both replicators. That is a useful category which encodes a qualitative difference. Fire is not a replicator. Viruses are. While fire might not be an interesting boundary case, transposons, prions and computer viruses might be. Viroids shouldn't really be considered a boundary case since they're really just naked viruses that take advantage of intercellular junctions in plants, but somehow people seem to think viroids are less alive than viruses.

  5. Interestingly, we don't have to be explicitly taught what things are alive and what things are not. Speculatively, there may be a central pattern generator that has some combination of animacy, agency, reproduction, and growth. Which does usefully capture all the living things knowable in the macroscale world that our ancestors inhabited for millions of years.

  6. Part of the problem with asking this question is there is no definition of "alive". Molecular biologists got bored with this question very quickly because it didn't advance any hypotheses. (Think of it as the "how many angels can dance on the head of a pin" question for this field; or if you're given to Eastern thought, "since yang is both hard and white, what is the logical relationship between these two things". That is, a problem which only seems to be a problem because of other assumptions which turned out to be wrong or unnecessary, and even if the question was meaningful, answering it turned out to be uninformative and arbitrary.) The most common definition used - again, not necessary for any experiment - is independent metabolism. You might say that an organic virus is not alive because they have no independent metabolism - this is the usual cutoff. What about chlamydia? This is an actual genus of bacteria which is obligately parasitic on host ATP. (A medically relevant genus no less, because it causes diseases humans.) Yes, it uses ATP. So do viruses once they're inside cells. So instead of "alive" why wouldn't we just say "independently ATP generating"?

  7. And yet, it does seem very unsatisfying to learn that "alive" - an apparently important distinction between the types of objects I see when I look out my window - is actually arbitrary. That's because I don't see anything that the term doesn't seem to work for. I see on one hand rocks, clouds, the roof of my porch, and on the other, flowers, birds and grass. Naked-eye observers of the natural world are the Newtonians of biology. Looking out your window, you can't encounter anything where your instinct of "alive" and the better category of "replicator" don't line up...

  8. ...but as soon as you see viruses or viroids or prions, your assumptions are falsified and these traits no longer overlap. Another place where the same debate happened, interestingly also outside the realm of every day experience was in the nineteenth century attack on the idea of vitalism, where a supposed distinction between living and non-living materials was shown empirically not to exist. So to stretch the analogy, Woehler was molecular biology's Planck, and instead of the ultraviolet catastrophe, he demonstrated the urea epiphany.

Number of COVID-19 Cases Correlates With Population Density

It seems fairly obvious that density should correlate with how fast a virus spreads. Comparing across countries or even states is difficult due to time of introduction as well as many other variables. This should be less of a problem (but certainly not zero problem) for a study of of cases by county within a single state. Therefore I looked at the relationship between density and cases. Keep in mind this is an ongoing pandemic so time of introduction will still make a difference, and for that matter there is no effort to control for other variables (e.g., difference in testing frequency by county.) Both axes are log 10 mostly to group points together. As you can see from the R^2 there's quite a close association.


The next and less obvious question is, if viral load (total number of viruses an infected person was exposed to) correlates with illness severity, you would expect that density would also correlate with deaths. There are even more variables that come into play with deaths - age and health of the population which definitely differs, as well as access to medical care and ICU beds. So I did the same thing for deaths; I'm not showing it since I found an R^2 of only 0.0845. I predict that a month from now that R^2 will be higher.

Editorial Clickbait about Psychiatry in the New England Journal of Medicine

I'm really disappointed in NEJM for publishing this piece by Gardner and Kleinman (G&K.) Overall this article is not helpful or useful. There is a cottage industry of psychiatrists writing hit pieces on our own specialty, and often they make coherent and actionable points that improve the specialty and ultimately patient outcomes. But of many valid criticisms of psychiatry, this article bizarrely focuses on two problems that pervade most of medicine, and implies that they are uniquely problems for psychiatry. The thesis seems to be that psychiatry has been damaged by reliance on a biological approach, which has stunted its ability to treat patients, and damaged our interactions with them by decreasing the quantity and quality of our interaction.

First: these two have apparently not been talking to many of their colleagues, inside and outside of psychiatry. How many physicians do you know, especially in cognitive specialties with lots of patient contact, who say "No, I don't have inappropriate time pressures on my patient interactions, and what pressures there are, are not worse than they were thirty years ago"? Most psychiatrists would love to spend more time with patients. When we don't, it's not because we've already gone through the checklist so we don't want to waste time forming rapport - it's due to the moral hazard introduced by the financial and administrative structure of modern medicine. The same argument obviously applies to many specialties outside of psychiatry.

The second part of their argument is that over-reliance on a biological approach is what has distorted psychiatry and prevented us from adequately treating patients. In case they haven't noticed, we do have psychiatric medications which work, that we didn't have a few decades ago. (They somehow fail to comment on the existence of SSRIs and second-generation antipsychotics, for example.) How is this the failure of a biological approach? It is trivially true that biological approaches to psychiatry have not yet been as fruitful as we would all like. The genomics revolution (for example) has also not benefited most branches of medicine to the degree hyped - yet. It's a bit premature to say that therefore, biological approaches like genomics have not yet benefited psychiatry and therefore will never benefit psychiatry. They have essentially not benefited any other branch of clinical medicine besides hem/onc - because it's easier to kill or poison certain cells (especially ones that are suspended structurelessly in fluid, rather than connected in a specific network, neural or otherwise) than it is to make them work better. We should expect that oncology would have been the first to benefit. In this G&K are rather like engineers in 1900 saying "we haven't achieved powered flight yet, therefore it can't be achieved ever." (Which, by the way, some engineers at the time did.)

It's unclear what G&K's solution is. Perhaps most tellingly, the voices I've seen online defending this article seem to have great difficulty understanding the definition of "syndrome", or the idea of treating empirically before the biology of a specific case or even the disease itself is clear is quite often the best approach (and again, this is not specific to psychiatry.) For instance, many psychotherapies have an impressive evidence base at this point, and if we don't understand psychopharmacology as well as we would like at the biological level, we certainly don't have anything like a fully articulated biological theory of psychotherapy either. If you have a treatments that can help - pharmacologically or otherwise - it's immoral to withhold it just because the science behind the treatment mechanism or pathophysiology is not settled. And as near as I can tell, that's exactly what G&K are proposing.

In Medicine, Rounding Works

Rounding is a time-honored tradition where doctors meet to talk about cases, either in a meeting room (the "rounding room" was named after a specific room at Hopkins) or at/near the bedside. Most often associated with inpatient medicine teams especially in training environments, the treating physician will present the case and discuss it with her colleagues. Not only is it thought that in this way, medical decision-making benefits from collective intelligence, but the anxiety provoked by immediate criticism (especially in trainees) sharpens one's thinking. A study in JAMA Network Open supports this. Teams here were internal medicine teams composed of multiple levels of training, from med students up to attendings. I don't think the findings would be too domain specific, but at a guess, I imagine the benefit would be even greater for psychiatry than for internal medicine, as psychiatry's diagnoses are fuzzier and more subjective.

Groups don't always arrive at better decisions than individuals - especially groups of non-expert individuals with no feedback - but teams with people who are experts, and who do get feedback benefit from collective intelligence, do better than individuals alone. So qualitatively this isn't surprising, but a problem in medicine is lack of quantitative thinking; especially in my specialty, psychiatry, where studies are constantly coming out showing that medical or psychiatric illness X increases the risk of psychiatric illness Y. No kidding! By how much is what we want to know. So what's the actual benefit of rounding?

For groups of 9, on average you need to treat about 4 people before you make a diagnosis that an individual would have missed (i.e. NNT is about 4.)

For groups of 5, NNT = 6.

For groups of 2, NNT = 8.

The simple plot below shows the % accuracy improvement per person based on group size, and again not surprisingly, there's a diminishing marginal return for adding more people. (Where does it go to zero? Nine is already on the big size for a rounding team.)


This of course doesn't take into account rounding time, which is a real consideration, and big teams are slow. Maybe the % improvement per minute drops at a certain point.

Therefore, don't hesitate to curbside-consult your colleague, because just by talking to one other person, every eight patients you're making a more accurate diagnosis.

An Obvious Healthcare Cost-Savings Proposal, That Doctors and Patients Will Obviously Resist

Arnold Kling draws attention to a proposal by Karl Denninger, which includes the following:
No government funded program or government billed invoice will be paid for medical treatment where a lifestyle change will provide a substantially equivalent or superior benefit that the customer refuses to implement. The poster child for this is Type II diabetes, where cessation of eating carbohydrates and PUFA oils, with the exception of moderate amounts of whole green vegetables (such as broccoli) will immediately, in nearly all sufferers, return their blood sugar to near normal or normal levels...This one change alone will cut somewhere between $350 and $400 billion a year out of Federal Spending and, if implemented by private health plans as well, likely at least as much in the private sector.
The tone gets even more pointed, and more accurate, further on.

Denninger further points out the core values-disconnect that makes talking about healthcare so difficult. That disconnect is that we are trading dollars and human suffering back and forth, and there's no way around this brute fact, ever, except to hide it from both buyers and sellers. This makes the system nauseatingly inefficient, whether we're talking about centralized planning or a free market.
Americans, and especially health care providers, do not want to think of health care as a commodity. The providers want to be paid, but they do not want to think of themselves as selling their services, so the payment comes from third parties and the price is hidden to consumers...All surgical providers of any sort must publish de-identified procedure counts and account for all complications and outcomes, updated no less often than monthly. Consumers must be able to shop not only on price, but also on outcomes.
This will be unpopular as both patients and doctors want to avoid responsibility for bad choices - but now that we're all paying for people to keep eating McDonald's and performing poorly-evidence-supported surgeries so they can buy a vacation home - we will have to make some hard choices.

Lying and Intention

Some years ago, I went to see a movie with a friend who has since passed away. (This is actually one of my favorite memories of her.) Relevant: the movie was Blair Witch Project. My friend was badly scared by horror movies (why did she go? I don't know, but she's a grown up, not my problem) and when I took her back to her house, she was still quite worked up.

I should add that it had been a very hot day, and her house didn't have A/C. It was still sweltering, even after midnight, so she knew if she wanted to sleep she would have to open all the windows, which she did. This is also relevant, because a) her room was a very small addition to the house, with windows on both sides of, and behind, her bed, in fact so close to the bed that a cruel person who likes scaring his friends could actually reach in from outside and grab her; and b) I am in fact the kind of person who would do something like that, and lie about my intentions, and had done such things many times before. (I'm quirky that way.)

"Can't you please just stay until my roommates get home?" she implored.

"No, I have to go home and go to bed."

A look of horror crept across her face and her eyes widened. "I know what you're going to do! You're going to drive two blocks away like you're going home, then park, and silently walk back, and wait outside the window until you see me nodding off, then grab me and scare the crap out of me!"

"No, I would never do that!"

"Yes! Yes you will! I know that's what you're going to do no matter what you say!"

"No. No, I am definitely going to go home, and go to bed." Despite her pleas, I walked out. I then got in my car, drove home, and went to bed. I slept very well.

The next morning around 6 a.m. - probably not coincidentally, around the time the sun rose - I was awakened by my phone ringing. It was my friend. "What," I mumbled as I picked it up.

"You asshole."

"What?" I said. "Me asshole? You asshole. You're waking me up at six in the morning."

"You bet I am! I've been sitting here on tenterhooks all night waiting for you to reach in the window and didn't sleep at all and you actually went home and went to bed!"

I said nothing, but I smirked.

"I can hear you smirking! This is exactly what you planned isn't it?"

"Listen," I said, "I did exactly what I said I would do. I told the truth. I did the morally correct thing, and you chose not to believe me, even though I was telling you my true intentions, and then acted on those intentions. So that's your problem. Now if you'll excuse me I have to get some more sleep." I hung up and turned off the phone. I slept very well.


One frequently discussed problem in the analysis of what constitutes moral behavior is that of the contribution of an actor's intention, if any, to the morality of the act.

I someone hits me with a car, if I am a consequentialist, I have no grounds to say that the act was more or less moral based on the intent of the person. If someone hits me with their car at 35 mph and breaks my femur, to a consequentialist shouldn't care if the person did it intentionally and was pleased by this outcome, or accidentally and horrified by it.

This is correct - only if the definition of "consequentialist" is narrow, and really means "near-sighted consequentialist" - someone who just cares about single, isolated acts, which in the confines of a thought experiment, is often the (unintentional) implicit assumption. But of course this isn't the case, and it violates our moral intentions and (if the two are separable) the actual reactions we have in such situations, or even just hearing about such situations. Even taking out the egocentric anger and desire for revenge likely to be incurred by someone who you know hit you intentionally and enjoyed it, you would be right to be concerned that this person is out there running around loose where they can hurt someone else - and a monster like that is unlikely to limit themselves to cars in such endeavors. That is - their intention predicts future actions, which is why it matters, even (especially!) to a consequentialist. The person who is horrified is less likely to do such things again, although even in that situation, if their horror is misaligned with choices they keep making (they were texting, they were under the influence, etc.) then this also figures into our evaluation - because it predicts future actions. A stronger statement is that without intention as a predictor and link to future actions, to talk about the morality of an isolated act is meaningless.

The law in most OECD countries actually gets this right, at least for murder, where it differentiates by degree. The difference in intent between accident and non-accident is obvious enough, but the difference between first and second degree murder is also important. There is something very different and more threatening about someone who murders after planning it out, rather than by unchecked impulse. If someone had a bizarre neurological disorder causing them to helplessly pick up long objects and swing them at everyone around them, you wouldn't want them walking around loose, but you would see that they were horrified themselves at this tragic illness, so you also would recognize that this is not a person who intends harm and whose other actions are suspect as well. (If someone you know to be unfortunately afflicted as a neurological-disease-stick-swinger calls you - from far away, hopefully - and asks for a donation to a charity, you're much more likely to think the charity is legitimate than if you get a call from someone you know to be an intentional, actually-enjoying-hitting-people stick-swinger.)

This is the same problem which makes certain human behavioral patterns appear irrational in the context of a necessarily limited, close-ended experiment, when in fact they are not. For example, it's a well-studied result in game theory that humans are willing (in fact, eager!) to punish cheaters even if the damage is done, and enacting the punishment has a non-zero cost. Yes, in a true one-round game, the rational thing to do is to stop one's losses and walk away - think of not getting in a pissing match with someone who cuts you off on the freeway - but this is a rare circumstance. The small bands we've lived in throughout most of history, where you were around the same people all the time and kept score on each other, would predispose exactly such a behavior to emerge - and in game theory experiments or one-time encounters in large populations, we may not be able to override our programming. Granted, in those relatively rare encounters, it is irrational not to override it - but again, these encounters are rare. And tellingly, unless you're planning to be the cheater, you likely minimize your time around, and interactions with, complete strangers. I've come to refer to these kinds of situations (either game theory experiments or in real-life, like each day on the freeway) as GOOTs - Games Of One Turn. Many finite-round games are known to strongly affect decision-making. For example, if you're playing a certain number of rounds of prisoner's dilemma, you know that there is no more revenge possible after the last round, so you plan to defect the last round. And your frenemy in the game knows it, and you know they know it, etc. So you defect one round earlier...et cetera, until the rational player who is optimizing payout and playing a finite game defects immediately on the first round.


HOW DOES THIS APPLY TO LYING?

There are truth-telling absolutists (Kant is the obvious example, but a modern defender is Sam Harris) who have difficulty ever justifying an intentional mistruth. In Harris's case this is especially interesting as he (correctly) defends the role of intention in moral acts generally. The morally justified lie in the murderer-at-the-door thought experiment that challenged Kant was most famously and tragically realized in the example of Anne Frank (Varden 2010), and in comparing Kant's argument to this specific event it often takes rather more argument than we might hope it should to justify why it was acceptable to deceive the murderous fascist occupiers.

The claim "lying is always wrong" - hereafter referred to as the naive theory of lying - fails because three related assumptions are clearly falsified, all of which are present in the true account I provided above.
  1. Bad Assumption #1 - identical agency: Humans are all equally capable of identifying and acting on truth; that is, we all have an identical set of beliefs about the world, are equally able to reason about them, and will therefore respond to the same information in the same way. (Kant's Golden Rule fails for this reason as well.) This could occur because of false beliefs, biases, or any other departure from rationality that leads to suboptimal computing of beliefs. (Sometimes an immoral person will deliberately create those false beliefs ahead of time and then deceive by telling the literal truth, as I did.)
  2. Bad Assumption #2 - moral isolation of speech from other actions: Speech is capable of communicating unfiltered truth mind-to-mind, and that the moral weight of a statement comes from how true it is, rather than the effect that you are intending to have with your statement. In this, speech is qualitatively different from other actions. (My intention was to use my speech as an act to deprive my friend of sleep and keep her up all night. That I told the truth should not disqualify from being, as she correctly identified me, an asshole.)
  3. Bad Assumption #3: cooperation-independence: Truth-telling applies to all humans, even if they are not cooperating with even your most basic interests (e.g., preservation of life and avoidance of needless suffering.) This alone justifies lying to the Nazi at Anne Frank's door. I would agree that it is correct that intentionally creating a false impression in someone else's mind is immoral because it's a form of harming them, but a) if someone intends to harm you, harming them in attempt to stop this is not immoral and b) one can certainly create a false impression by telling the truth, as will be explained below. (In my true story, if my friend had said "Okay, go home, I'll be right here" and then gone to someone else's house to spend the night, would that have been immoral? That is, would I have been justified getting mad at her if I had acted her on her lie, come to the window to scare her, and she was gone? How dare she deceive me like that!)
Because these bad assumptions are false, applying the naive theory of lying to behavior produces inconsistent results with respect to harm we cause by speaking to people. This makes it an inadequate moral rule. (If your theory of morality does not have a place for harm minimization in general, the argument we would have to have is at a much more profound level.)

It is telling and under-appreciated that children as they develop a theory of mind often test the (widely accepted) naive theory of lying against the principle of harm minimization. Right now you can probably think of a smirking child who told you something that was technically true, but intended to deceive you or cause you some other problem. Cute at first, but if they keep doing it through to adulthood, you realize you're dealing with an immoral person.


FALSIFYING THE NAIVE THEORY OF LYING - ABSTRACT AND CONCRETE

There are infinite scenarios that illustrate this, but in the abstract, the most common scenario is this. (Concrete examples follow each abstract description.)


Person P believes fact X.

Q believes not-X.

In reality, not-X is true. (That is to say, P violates naive theory of lying Bad Assumption #1 - identical agency.)

Not only is Q quite confident that not-X is true, but they quite clearly understand that P believes X, and for bad reasons.

Q tells P fact Y (which is true!), knowing full well that this will cause P, based on P's false belief of X, to perform action A, which harms P. (Or, Q just makes no effort to convince P that not-X, allowing the false belief to stand.) (Bad Assumption #2 violated - moral isolation of speech from other actions.)



Notice that nowhere did Q lie. Q identified a false belief of P that warped P's judgment, and told P something true that will make P do something harmful to himself in the context of P's warped judgment, intending for his true statement to make P harm himself. Q did not lie, but rather used a true statement to create a false conclusion in P's mind that harmed P. Q is immoral.

There are many, many concrete examples in the world of financial transactions, where person P either has a false idea about the value or quality of an item, or the movement of a market - which Q does not correct because they benefit from the transaction.[1]

Let's say you're at the base of a cliff you've climbed before, and you know the view from the top is beautiful. As a local, you know that what appears to be the most obvious route is actually quite dangerous, because the rock is crumbly and anchors can pop out, risking that the climbers will fall and die - in fact this has happened many times, especially to outsiders who won't listen to the locals. A couple of tourist climbers show up, and you overhear them talking about how this rock face looks like sturdy solid granite, and they're planning to go up the obvious (but unknown to them, most dangerous) route. If you say nothing (to warn them about the crumbly rock), you're immoral. If you say, "The view at the top is great!" you're falsifying Bad Assumption #2, and you're really immoral.

The obvious objection is that you are, in a sense, lying by omission. You would tell the person it's dangerous, and you certainly shouldn't induce them to try it! (Yes, obviously, but again, by the naive theory of lying, you would've done nothing wrong.)


LYING TO CONVINCE A DISTORTED BRAIN OF THE TRUTH

So, let's make things more interesting, returning to the abstract formulation and introducing a very real problem, that of differing beliefs causing people to make different decisions (thus violating Bad Assumption #1, identical agency.)


Q (who in this scenario is a better person) does try to convince P that not-X.

P refuses to believe Q despite Q giving good reasons.

Q recognizes P's false belief structure, and understands that by telling untrue fact Z to P, P will make a choice in their best interest, owing to their distorted beliefs.

Q tells fact Z to P - that is, Q lies to P - and P makes a better decision than if Q had told P the truth.



Back to the rock climbers. If you're not a jerk, you go over to visitors and say, "I heard you talking about your route. I have to tell you, this whole cliff is kind of crumbly but the obvious route is really dangerous and people have died on it. I really think you shouldn't try it."

As they sort their gear, the visitors scoff. "Ha. I don't think so. These local yokels might be scared of it. Or maybe they just don't want outsiders climbing their route. People told us the locals here are liars. If you're a local I'm not going to believe anything you say. Are you?"

If you tell them the truth, you will harm them. If you lie and say "Nah, I'm visiting for the weekend from L.A. and a friend of mine there knows someone who died on that route" then maybe they'll listen. If you are scrupulous and try to change their minds, they dismiss you as a local, climb, then fall and die, you would be pretty immoral to say "Well with their false belief they put me in a bad situation, and by choosing to put them in more danger which led to their deaths, I made the right decision."


LYING TO PEOPLE TRYING TO HARM YOU

A final abstraction, for Bad Assumption #3, cooperation independence. Here, Q is again a bad person; maybe even a Nazi at Anne Frank's door.


P knows that Q intends to harm them.

Q's harming them requires information about P, provided by P.

P tells C to Q, knowing that not-C is actually correct. P lies to Q with the intention of protecting themselves or others.



One way to think about this for the naive theory of lying crowd: if lying is on the spectrum violence, then when someone intends to commit violence to you, lying to them is a form of self-defense, and in fact much better than the physical violence one might otherwise have to employ. This stands independently of the rest of the argument and is consistent with the naive theory of lying.

Back to the cliff. You, the local, are back to being a jerk again. In fact, you've repeatedly gotten visitors to try to climb the most dangerous route by telling them about the view, so that when they fall and die, you can collect their gear. ("Hey, I'm not lying to them! Not my problem if they come to the cliff and are careless about the rock quality on the route!") But the authorities have started to suspect someone is doing this intentionally, so now in your pre-climb conversations with your victims, along with inducing them to climb by extolling the view, you wheedle out of them whether they have any connection to law enforcement. Of course this time, the pair of climbers that comes is indeed law enforcement, but undercover. When you ask, they say "No." They're trying to stop you from doing this to other people, and by identifying themselves, they couldn't do that. They are behaving morally by responding to your violence with defensive, much less severe violence, and trying to stop you from harming others. (Naive-theory-of-lying people: would it matter if instead they technically didn't really lie and instead said "Hey, do we look like law enforcement?" To a five-year-old who doesn't understand theory of mind, possibly.)


THE MORALITY OF LYING AND INTENTION

An improvement on the naive theory of truth-telling is this. If we intend to help people and intend to avoid harm, we should say things that will accomplish these things. Intention is quite important, because as with other actions, it predicts the speaker's future actions. The default assumption should be that this is almost always accomplished by telling the truth. However, once you have evidence that telling someone the truth will not help them or even harm them, and/or that lying in an extremely limited way will help (or that you're dealing with someone with bad intentions, i.e. who's not cooperating with even your basic safety), it is acceptable to say untrue things. We can call this theory of intention and lying helping by intentionally creating an accurate model - HICAM.

In those rare instances where we lie to benefit someone, we can call those pro-social lies. (Intentionally differentiated from white lies - more on that below.) But we can also categorize the ways of causing harm by speaking.
  1. Active lying or bullshitting. Actively creating a false impression without the intention of helping someone.
  2. Letting weeds grow. Allowing false beliefs to persist with the intention of harming someone.
  3. Manipulation WITH the truth. Telling the truth in a way that one intends to create a false impression, often by using pre-existing false beliefs.
Notice that this definition does not justify "white lies", nor have I used the term. A working definition of white lies is lying that spares people's feelings and otherwise have no effect. I might seem to be siding with the naive theory of lying people when I say that white lies are quite dangerous, for the reason that emotional impact absolutely is an important effect, and psychologically, it's a bit too easy to avoid difficult conversations by telling ourselves we're just telling white lies.

Moral thought experiments (including this one) often use exotic examples, although I bet more people were rock-climbing today than switching trolleys between tracks. But examples in your own life likely abound. That said, if you have kids, you have very likely told a few half-truths or outright whoppers to motivate them, keep them out of trouble, or otherwise improve an outcome when their little brains would likely not have responded as well to a carefully marshaled rational argument. Why? Because children's agency is poorly formed (Bad Assumption #1.)

The same is likely true if you have family members or clients with some neuropsychiatric illness who would otherwise not be cooperating with you or otherwise make horrendous, unintentionally self-harming decisions; for example dementia. Some years ago, a relative of mine with dementia eventually progressed to having no short-term memory. This person was quite attached to her family home. She lived in a nursing home for about two years but believed the whole time that she had just arrived only a few days prior, and would shortly be returning home. Of course the home (which had fallen into disrepair as she deteriorated) had quickly been sold. Most of her visitors avoided the question of how long she had been there or commenting on the house, but at one point a well-meaning person, realizing this lady thought she just arrived and that she would shortly be returning home, told her the truth. This resulted in an emotional meltdown and suicide attempt. The next day of course, my relative had no memory and again thought she had just arrived and would soon be returning home. Was her well-meaning visitor a moral person? Would she have been moral to repeat this episode?

There are many milder but more common versions of this. Someone adheres doggedly to a certain authority. Someone dismisses you because you do not, or you're the wrong religion, ethnicity, political affiliation, etc. These are themselves not very pleasant reasons to be disbelieved, but what is your responsibility here? Say you own an auto shop, and a customer you don't like brings their car in. Inspecting it, you notice that the brakes are about to fail. Because you don't like this customer and you know he's a racist, when he comes to pick up the car to find out what work needs to be done, you intentionally send a black employee (who's in on it) to tell him he needs his brakes replaced, expecting full well the customer will refuse because a black person is telling him this, drive off, and crash when his brakes fail. Yes, he's no prince charming, but if someone told me that story, with that clear intention, I would worry about the shop owner's character and not want to be around him. (In point of fact, when someone is worried that a message will be ignored or taken the wrong way because of something like this, they do often use a messenger more likely to be taken seriously and accurately.)

And finally, ask any physician how they motivate their patients with low motivation, cultural barriers, or poor health literacy to do things that will keep them alive. It's hard enough in primary care. Try psychiatry! The temptation to severely spin the truth to improve outcomes for your patient arises frequently, and sometimes wins.


PROBLEMS AND FURTHER OBSERVATIONS ABOUT HICAM

The obvious (and correct) objection to any non-absolutist model of truth-telling is that it provides a very slippery slope. When you free yourself from a commitment to absolute truth, it becomes maybe a little too easy to justify fibbing in what you've convinced yourself is someone else's actual best interest. Consequently, following these rules, you should still expect opportunities for pro-social lies to come up quite INfrequently, and you also have to commit to real honesty about your motivations for telling what you believe is a pro-social lie. You have to accept that when you tell a lie, when you think you've found a pro-social motivation, you're probably deceiving yourself. The analogy here is to uber-empiricist Hume's statement that (paraphrasing) despite his identification of the problem of induction, still, if you think you've found a violation to the laws of the universe, you've probably just made a mistake.



Above: Left, how most of us think of the relationship between epistemic and instrumental rationality. Right, a more accurate scheme.


However HICAM does relate to some distinctions made in epistemology and observations from the psychology of mood and rationality. Epistemic rationality is what we usually think of as rationality, when you can make a valid argument. Instrumental rationality is action that increases utility, with no semantic component. I am being epistemically rational when I can describe and predict a thrown object's course mathematically; I am being instrumentally rational when I catch it without thinking of that (and so is a dog.) People tend to think of the two rationalities as separate domains or "two sides of the same coin", but a better argument is that epistemic rationality is a subset, a special case of instrumental rationality. Not controversial; speech and thought are actions. Consequently there will be times - rarely - that the actual outcome of computing someone else's statement will be different than what would have occurred if it were computed and acted upon rationally (as with a person who holds false beliefs - Bad Assumption #1, identical agency.) Saying something false or invalid to get someone to do something good for them is one of the rare times that speech is ONLY in the realm of instrumental rather than epistemic rationality (see below.)


What's more, there's an interesting finding in psychology described as depressive realism, where depressed people actually make better predictions about their own performance than non-depressed people. In seeming conflict with this is the robust finding that optimism predicts success (Bortolotti, 2018.) It's as if we have to choose between seeing reality as it is and being depressed, or delusional and happy - and most perplexing, successful. Fellow psychiatrist-blogger Scott Alexander uses the analogy of mood as being like an advisor to someone who motivates their client or pulls them back based on historical performance. Depressed mood is like an advisor to someone who always fails, telling them not to ever try anything, because history predicts they will fail again; as contrasted with the adviser of someone who always succeeds (happiness, optimism.) Here we see another domain where optimizing more for instrumental rationality (the less rational but more motivating optimistic beliefs)[2] produces better outcomes than optimizing for epistemic rationality (the glum, accurate beliefs.)[3] All this is to say, the occasional leaking of speech out of the epistemic domain into the purely instrumental domain - prosocial lies - is entirely compatible with what we know about human behavior. We can think of the distorted beliefs held by optimistic people as prosocial lies we tell ourselves.

All this justification of making false statements as long as they "work" is likely to make rationalists squirm, and indeed the alert reader with supernatural religious convictions might say: "Even if you think religion is false, doesn't HICAM and especially your argument in favor of prosocial lies justify believing it? Isn't religion actually the best example of an instrumentally helpful, though epistemically irrational belief?" Indeed I wrote about exactly this problem some years ago, arguing that as a set of untrue statements - lies - religion is immoral, even if it sometimes inspires good acts that otherwise would not have occurred. (That's one of many reasons.) How can I make such a claim, but defend HICAM? Again - we would expect pro-social lies should be very rare, and require strong justification. Contamination by selfish, anti-social motives is always a danger. Therefore the argument is really a quantitative one - maybe we might expect to tell a pro-social lie a couple time a year, rather than fill an entire book with them. Much more than that, and it's overwhelmingly likely most of them are actually someone telling plain old lies, anti-socially. So if ever you catch me intentionally building a whole delusional world around someone that I claim is in their best interest, I would certainly be acting out of immoral intentions.

Finally: while I've written a lot about the harm that can come about from saying true things to a person whose thought process is distorted by false beliefs (thus leading that person to actually make bad decisions, despite having told them the truth), this is less often a problem than it otherwise might be. The reason is that people who verbally claim false beliefs often find reasons not to act on those claimed beliefs. Example: someone says to you "my favorite football team will definitely 100% win the game tomorrow, since the previously injured quarterback is back in the line-up." But it turns out that 2 minutes ago it was just announced that actually, the quarterback will NOT be playing tomorrow. As an unethical person, you rush to lock down the bet while your interlocutor holds a false belief (letting weeds grow.) But suddenly they get cold feet, often with a disingenous "Gambling is immoral" or "I don't want my fandom to be polluted with money", etc. In fact humans have lots of "speed bump" heuristics, to keep false beliefs from propagating too far and to keep us from overcommitting, even though epistemically we can't really explain it that way (see the endowment effect for one such example.) It's interesting to note that it's often the newly converted who don't have the speed bumps specific to a new set of beliefs who get into trouble. On the other hand, there are people with severe psychiatric illness, who have a brain which is physically different from most other humans. They really believe their delusional beliefs, judging by how they endorse them with action, with no speed bumps.

FOOTNOTES

[1] To be clear, this is not a claim that all transactions are immoral. When we trade, we necessarily hold different valuations of the things being exchanged, otherwise the trade would be irrational. As real objects will inevitably have different values to different people in different situations, this is not an obstacle to moral rational trading. However, if one is trading a more abstract entity that only holds value in terms of its tradable utility, or predicting an outcome that is only connected through arbitrary agreement, and especially in zero sum scenarios, then objectively incorrect valuations by one party is likely to play a larger role in the trade. Case in point, bets, commodities, or stock options.

[2] Assuming that our delusional (but success-producing) optimism has been selected for by evolution, I often amuse myself by wondering whether, if Homo erectus could understand psychiatric nosology, they would view their descendants (us) in horror, running around manic all the time as we might appear to them.

[3] Of course different levels of optimism or pessimism are rational for different risk:benefit scenarios, just as in game theory, penalty and payout determine the most rational strategy. Case in point: one of the things that cognitive behavior therapy or social anxiety aims to do is make people re-evaluate the actual risk of social interactions. So what if someone doesn't like you or won't say yes to a date? Does it physically harm you? The payout, while unlikely, is high, and the risk (once you get past your anxiety) is almost zero. On the other hand, this would be a terrible approach for rock-climbing. Antonio Gramsci (quoted by Steve Hsu on his blog) expresses this nicely: "Pessimism of the intellect, optimism of the will."

Procrastination Variants: Narcissistic Subtype

This post is research only and should not be taken as medical advice or treatment recommendations.


Many things in psychology are multicausal, and/or have subtypes. Initially this causes difficulties in trying to study them. Lumping together different illnesses has obscured the truth many times in the history of neuroscience and mental health, and is certainly still doing it now. (In the early twentieth century most physicians would have considered schizophrenia, autism, intellectual disability and dementia the same thing, and now most educated Westerners have some idea that at least these are different conditions, if not what the symptoms are.)

Procrastination is a problem for a lot of people that gets surprisingly little attention in the psychology literature, relative to its prevalence and the amount of suffering it engenders. A simple model relies on executive dysfunction affecting set-switching, and it works like this. You want to accomplish B, but you have to do A first to get to B. A is unpleasant and merely an instrumental goal. If you have poor executive function, you can't get yourself to start doing A; you "put it off". Or, you're already doing X, which although unrelated is much more fun in the moment than A would be, so you REALLY can't get yourself to start.

No doubt this model does usefully describe many people's experience, and even for the people best described by the model I'll advance below, an executive function deficit probably does play a part to some degree in just about every chronic procrastinator. But the pattern many people describe has several inconsistencies that suggest that what's really motivating the procrastination is avoiding the threat of ego injury - especially in narcissists, to whom any damage to self-worth by being less than perfect in a core value is destructive and terrifying.

I've made a number of observations from scouring the limited literature, as well introspection, observation of patients, and reading others' introspection, that suggest to me that for a large subpopulation of procrastinators at least, the problem is driven mostly by character rather than executive dysfunction. Even before looking at the literature, based entirely on my observations in the clinic, I noticed a commonality in the patients who would complain of procrastination difficulties. They're usually male and middle-aged or younger. They often display a degree of alexithymia, or even more interestingly, very specific alexithymia, toward anxiety only - they either never notice that they feel anxious, cannot name it when they do, or actively deny feeling anxious. I often suspect that this is motivated by anxiety being an ego dystonic emotion in male narcissists (to be anxious is to be weak, which is unacceptable.) In treating these patients, I've measured their symptoms and progress with the Irrational Procrastination Scale in my practice (hereafter IPS), though you can also find the Pure Procrastination Scale (Steel 2010), and two comparisons (Svartdal et al 2016, Svartdal and Steel 2017.) (Steel has his own site here with more information.) I've never taken objective data on narcissistic personality though the instrument most commonly used is the Narcissistic Personality Inventory (the NPI.)

Literature review shows two things: a small literature investigating possible procrastination subtypes, and a tiny but intriguing signal about a narcissism-procrastination connection. There are a few more papers indexed by procrastination and compulsive personality, among them Primac's paper showing the success of a brief therapeutic intervention in compulsive personality decreasing both narcissism and procrastination. Of the three procrastination subtypes noted in the literaure (avoidant, arousal, and decisional procrastinators) narcissistic procrastinators as I describe them below would most closely match the avoidant subtype. Some studies have found differences in the subtypes, for example in their activity at different times of day (Díaz-Morales et al 2008.) However Steel in 2010 performed a meta-analysis concluding that there is no evidence for the subtypes as distinct entities. Lyons and Rice (2014) reported on avoidance and arousal procrastination subtypes specifically and found relationships with secondary psychopathy and the Entitlement/Exploitativeness facets of the NPI. In contrast Nawaz et al (2018) did not find a correlation between the IPS and the NPI. Shame is known to be at the core of pathology in narcissism, and Fee and Tangney (2000) found correlations in procrastinators between shame, but not guilt. Wohl et al (2010) found that students who forgave themselves for procrastinating while studying were better able to overcome study procrastination in the future, again suggesting a role for shame in the behavior. Mann (2004) noted avoidance effects proportionate to narcissistic injury in undergraduates. There is a slightly stronger signal for procrastination and obsessive personality - suggesting a common thread of perceived poor self-efficacy. A study comparing procrastinators versus non-procrastinators did not find differences in the cognitive abilities they measured, but did conclude that "Further research must provide evidence for persistent procrastination as a personality disorder that includes anxiety, avoidance, and a fear of evaluation of ability" (Ferrari 1991.)

What all this strongly suggests is that narcissism plays a role in procrastination, if not in all impacted procrastinators, then in a significant subpopulation. In addition to the literature cited here, here are the observations I've made of patients that support a narcissistic subtype of procrastinator and a mechanism for the behavior.

CLINICAL OBSERVATIONS
  1. Some procrastinators have reported that being sick or sleep deprived makes it easier for them NOT to procrastinate. This flies in the face of the executive dysfunction hypothesis. They say, basically, "I'm already miserable, so why not just do the thing I don't want to do." This suggests that what they're avoiding with procrastination is something that makes them feel generally bad, and when they already feel that way, there's no point in avoiding the task.
  2. This subtype of procrastinator doesn't just forget about the task. They usually don't just forget to do it; or, remember, but not feel like it, and just put it out of their minds. It's actually continually on their minds while they're avoiding it. This is also very unlike executive dysfunction.
  3. Many procrastinators have the experience of having TWO things they're procrastinating about, and they switch which one they're avoiding. This pattern is possibly the most instructive of all of them here, because of how little sense it makes without this model. For example, someone is supposed to do A all day, but avoids it. Then a deadline approaches for B (say, they're supposed to start getting ready to leave for an important meeting.) Then they actually do start doing A! If they're concerned about being injured by not doing perfectly at these activities, at some point anticipation of B (which they think they will do badly at) builds so much that they need some distraction. Now, the prospect of failing at A is further away and therefore not as painful, and they'll be partly distracted from A by impending B anyway - but more importantly, they'll be distracted from thinking about failing at B by doing A half-assed (and in narcissism, there is often constant activity to avoid feelings of worthlessness by using superficial productivity.) Tim Urban's description of this phenomenon is here in cartoon form. Briefly: it's time for him to leave for an appointment - Task B - when the Procrastination Monkey says "that work you were trying to do all day, I've changed my mind and suddenly I'm into it.") Note that strong focus on another task is not what you would expect from impulsivity either.
  4. Sometimes, once a procrastinator finally begins working on the avoided task, they explode with anger if they have to move on to something else. At first glance this would appear to be a perfect example of poor set-switching and therefore eminently explainable by the executive dysfunction model (autism spectrum people do this too) but you can actually differentiate based on the nature of the task - if you can switch to a self-worth-supporting activity, the narcissistic procrastinator would resist less, while to the autistic person the nature of the new task would not matter. In fact the more fun-for-its-own-sake is the new task, the more the narcissistic procrastinator would resist (don't you dare ask them to play video games once they finally get started on the previously-avoided task! But asking them to work on a boring, important tax document might be alright.)
  5. Procrastinators often use words to describe the way they feel like "worthless" or "useless", classic for wounded narcissists. They absolutely consider their procrastination a huge problem. Contrast with ADHD patients who avoid work, and for whom the avoidance is often fairly ego-syntonic.
  6. Many procrastinators describe doing pointless, un-fun busywork while worrying about the thing they're supposed to be doing. Tim Urban has a related idea called the "dark playground", but on the dark playground you can do fun things (while feeling guilty about them); I'll call this domain "busywork purgatory". Tellingly, it's always meaningless busywork. It's never something fun (well I'm not doing it, might as well play video games); it's not something else important. It's trivial, and it's usually something continuously attention-occupying that can be completed that day (for a burst of that feeling of accomplishment.) Many people have experienced the urge to clean the dorm room instead of studying, but dorm room cleaning is actually more useful than most busywork purgatory activities.
  7. A culturally-influenced aspect: in modern America there is a premium on productivity and success over most other characteristics. In a culture where (for example) loyalty to religion or family is most prized, I would expect that instead of busywork purgatory, the procrastinator gets stuck in prayer purgatory or doing-things-for-your-family purgatory, to prop up their self-worth.
  8. Probably the most disabling impact of this procrastination subtype: people reverse prioritize, spending more time on unimportant activities and starting them earlier and more easily. I've heard procrastinators say that they can tell how important they think something is by how easily they work on it or how relaxed and creative they can be about it (see this Tweet by someone who appears to be admitting to reverse prioritization.) With executive dysfunction alone, you would expect random order of work with respect to actual priorities, as opposed to a reverse ordering. Procrastinators are therefore often able to be quite productive at something that is not important to them. Paradoxically, if their productivity and success lead that thing to be a central part of how they measure their self-worth, they will start procrastinating at it. People will described starting to feel "trapped" and that's when they start to procrastinate. I would argue the behavior is not reactance but rather avoidance of ego-threat. Again, pure executive dysfunction would predict a random order or a tendency to always do "shiny" fun things, not reverse-prioritization of things that is deemed unimportant.
  9. Some procrastinators suggest that recent successes make them less likely to procrastinate, possibly because suddenly they have an expectation of a more positive outcome as a result of their efforts, rather than only negative outcomes (and this thought distortion is actually reinforced by reality in previous instances; part of the problem is that their outcomes really are negative, and they've taught themselves this quite effectively.) This also suggests that the problem is not only do narcissistic procrastinators envision a negative outcome in the end, they get no positive feedback from the intermediate steps along the way because there's no feedback in the form of external praise. Thinking about it this way, there's literally no reason to start the task, because it will be at best neutral while you're doing it, and then bad when you finish.
  10. A bizarre compensation behavior I've heard from multiple procrastinators is the pattern of performing an otherwise important task out of context, after the fact, and alone (where it has no value to anyone.) Bizarrely they will act like their completion of the task is exactly equivalent to having done it in the normal manner and time, all the while knowing exactly how childish and strange it is. I know of one person who was going to run a marathon, panicked because he thought he would do badly and didn't get up in the morning to go - but then showed up to the deserted starting line four hours late, ran the course, then actually emailed the organizers to yell at them - "What kind of a race is this? No aid stations?" (because they had long been taken down) "No one to hand me a finisher's medal at the end?" (Yes, because the race was over and everyone had gone home.) This person actually followed up for a while with angry phone calls and emails, fully aware how ridiculous it must sound but feeling compelled to do so; he said if he hadn't done this he would've felt "weak", classic for a male narcissist. Another example of this bizarre behavior was one procrastinator who routinely waited until after customer service lines shut down for the day to call (his bank, to change his password, etc.) He wasn't aware of doing it intentionally, but repeatedly noticed that it was 5:02pm, and it was time to call his bank. He would leave angry messages if there were voicemails, post tirades on companies' social media feeds, etc. He said he noticed he felt a strange satisfaction and even comfort in getting angry, and admitted to being oddly disappointed on those occasions when he called and got a live person who could help him. He stated the task was usually one where he wasn't sure if he would be successful or would know how to "navigate the system" to a successful outcome.
  11. The types of tasks that this subtype procrastinates on are rarely solo activities, or tasks with certain outcomes. Going for a solo hike, even one which involves complex planning, does not threaten to ego-injure the person with possible failure, nor does it provide an opportunity to fail in front of anyone else.
  12. If the person is angry at someone, especially at an authority figure telling them to do the task (less likely a competing peer), the procrastinator will engage in very thinly-veiled passive aggression by doing a previously-avoided task well and on-time, often fantasizing that they are frustrating the expectations of the authority who expects them to be late. Anger at authority cannot be the sole explanation, since the person knows that they are doing what the authority wants. Being less likely to behave this way toward peers is not as good an explanation as fear of ego-injury from credible critics (low confidence in success in front of peer competitors who are credible critics is less tolerable than say, a boss who the person is angry at and no longer considers credible.) While the sympathetic activation could be responsible for the focus (again, arguing for a simple executive dysfunction model), anger is known to focus narcissists.

Synthesizing these observations, the narcissistic subtype of procrastination is not the same as the avoidant subtype, but of the three traditionally considered subtypes, avoidant is the most similar. The model for the narcissistic or ego-threat subtype of procrastination is as follows. A person with some traits of a fragile narcissist, likely in the context of some executive dysfunction, encounters some task they have to do. This task is part of a series of actions leading to a goal that they intellectually want, which they consider quite important to their core identity - something that reflects on who they are and want to be, in front of other people, especially those who can credibly criticize them. Because they have poor confidence and/or unrealistically high standards, they feel they are likely not to succeed. Given their character structure of having a fragile self-worth that must be propped up with perfect external achievements, this is a profound ego-threat, and they feel anxiety contemplating the outcome of the task. Consequently they avoid doing it, but not thinking about it. They substitute either activities which distract them with continuous activity and certain near-term positive outcomes (no matter how trivial) or another otherwise-avoided important activity, but one which is farther in the future (and therefore, the ego-threat is farther off as well.) They finally undertake the avoided task when the time is so low and the threat looming so immediately that their awareness of the damage they're doing to themselves overwhelms the comfort they get by distracting themselves. If there is some way for the person to feel they can say to others they completed the task but WITHOUT exposing themselves to criticism and ego-threat, they'll do that, sometimes even if it's patently ridiculous; e.g. doing the task when no one else sees them and after it no longer matters. If the person already feels bad in general (from physical illness) or angry, even at an authority figure telling them to do the task, they are paradoxically more able to complete the task.


TREATMENT

My complaints about the paucity of procrastination research are partly driven by having treated it in my own practice, and having to round up what little evidence there is and then use "clinical judgment" for the rest. To round up the pharmacotherapy options: there are basically none, and in particular, there are none for the subtype I propose here. There is very indirect evidence for amphetamines (in one paper, college students abusing amphetamines reported less procrastination) but again, if these are all types procrastinators mixed together, such an indistinct smeared-out result is exactly what you would expect to see. The following is not a treatment recommendation - but I tried propranolol with a patient who had comorbid non-pathological social anxiety, used it a couple times and thought it helped, but he was much more successful with CBT (more on this shortly.) There is no evidence on Pubmed for other stimulants, benzodiazepines, beta blockers, or the SSRIs and SNRIs available on the US market. I've had people report that caffeine makes them work faster and focus and lifts their mood, but in fact after it wears off they realize that caffeine just helped them do more tasks in "busywork purgatory" - it didn't help them focus on the true high-value tasks.

The best evidence for successful treatment is from psychotherapy, specifically for CBT, which is also what has far-and-away worked the best in my own experience. Rozental et al have two studies which show among other things that in-person CBT with a therapist is the same at end of treatment as internet-based self-guided CBT, but the in-person people maintain their improvements better over time. Improvement was was over a full standard deviation from the control (!) but only about a third of participants improved - also consistent with my own experience that it doesn't help everyone, but the ones that get it, really get it.

This treatment does not differentiate by subtype or provide information that would let us infer about the relative benefit for narcissistic vs other mechanisms of procrastination. So what would I expect would be most successful approaches in CBT for narcissistic procrastination? (These therapeutic maneuvers are inferred from the model of narcissistic subtype procrastination above, but should be tested empirically in placebo-controlled studies and therefore remain speculative.)
  • Exposure therapy for failure and criticism of your core attributes. As a therapist - have the patient make a list of the things they consider core important attributes, skills, and values they offer, and people who are qualified to evaluate them against those standards. Perform role-play or imaginal exposure.
  • Learn to identify the anxiety that comes up when you start to avoid something - name it and develop a counter-habit, like working on the task for five minutes. As a therapist - have the patient tell you tasks that they procrastinate on. "Ambush" them during therapy, mentioning one of them out of the blue, then hit "pause" and ask the patient what it made them think of and how it made them feel. Keep a journal with successes of when they successfully fought back against the feeling outside of therapy, where it worked for at least five minutes (only track the successes, not the failures.)
  • Enlist a significant other, roommate, family member etc. to check up on you and give positive support when you finish tasks. (And don't avoid asking them out of shame, worrying you'll appear weak, etc. which is why this usually doesn't happen.)
  • Develop a habit of remembering that the individual steps do have value, even if you have to imagine others praising you for completing them. Envision a realistic positive outcome and how it will feel. Break things down into very very small steps, remind yourself this is how successful people do it (don't minimize by saying that means you're weak) and then pay attention to how you knock out these tasks - a success spiral.
  • Radical acceptance and forgiveness - we have certain abilities, we're going to screw up sometimes, and we're fine the way we are. Be consciously aware that castigating yourself mentally is not going to help you change, and in fact will do the opposite.

AFTERWORD: Why is Procrastination Seemingly So Much More Prevalent Now?

Procrastination is certainly not new in this or the last century. What does seem to be new is the number of people affected by it, and there's probably an easy answer for why that would be so. When you're stuck in the Malthusian grind like most of our ancestors were until about a century ago, your life is a series of constant emergencies, and we should expect that our brains are adapted to focus in this way, on near-term impending disasters with short time horizons and only a few concrete elements. (Starvation, fights, etc.) And indeed procrastinators often do quite well under pressure - they often report this as an excuse early on in their lives for why they always work up to the deadline, until they're honest with themselves about how out of control their behavior really is. (This is also borne out in the literature on the arousal subtype of procrastination.) It's interesting that stoicism as a coherent philosophy of classical antiquity was largely a philosophy of patricians, and its texts contain lots of subtle signals about their status by complaining that it was hard for them not to waste their time, i.e. not to procrastinate with trivia. This might have been a problem for an emperor or senator, but a subsistence farmer in a Roman province rarely had the luxury of stretches of time without highly activating direct threats to survival. Today we all live better than senators did in that era, which is to say we all have stretches of unstructured time and no threats to our survival - although notice that the things that finally do motivate us, even in procrastination, are all perceived threats.

There is also speculation that narcissism has become more prevalent as time has marched on. This is less than a settled point and I won't go into the debate here, but if that's the case, and narcissism does contribute to procrastination, you would expect to see more procrastination.

A third possibility is the cognitive parallel to the hygiene hypothesis. Immune systems, when not challenged sufficiently by invading pathogens, get very paranoid, and are more likely to mount autoimmune attacks. In the comparatively sterile modern environments where we now live, this is a problem. In the same way, in the absence of constant emergencies, the human threat detection system has more false alarms, and the one threat that does still exist is the threat of criticism, disapproval, and being perceived as weak (especially if you're male.) While such disapproval in the paleolithic could result in your death if you were thrown out of the tribe, today it seldom means anything of the sort. Un-learning our exaggerated social threat responses will likely be one of the central mental health tasks of the twenty-first century.

Psychiatrists Per Capita in the US, in Outpatient Practice Terms

The number is psychiatrists per 100,000. Data from Dartmouth Health Atlas. If you make simplifying assumptions, you can get an idea what that means. 1 in 6 people lives with mental illness (currently, not lifetime prevalence.) So if in your city there are 10 psychiatrists per 100,000 people, that means 1 psychiatrist per 10,000 people, and 1 psychiatrist for 1,667 people with mental illness. How long would it take to see them? The most under- and over-served areas are Oxford, Mississippi with 3.4 psychiatrists per 100,000 and San Luis Obispo, California with 36.5 psychiatrists per 100,000. (although I'll wager the later is counting psychiatrists at Atascadero State Hospital.) If you assume all these people being seen on an outpatient basis, by psychiatrists working 48 weeks a year, 5 days a week, with 16-30 minute shifts per day about 2/3 full, then in San Luis Obispo you could see your whole share in a little over 2 months (that is, the average follow-up time would be two months.) In Oxford it would be just under two years.

You'll note the long tail, which begins right around 15 per 100,000, and those locations are: Morristown NJ, Alameda County (Bay Area) CA, New Orleans LA, Honolulu HI, Springfield MA, Durham NC, Santa Cruz CA, Ridgewood NJ, Hartford CT, Portland ME, Hackensack NJ, Lebanon NH, East Long Island NY, Pueblo CO, Evanston IL, Baltimore MD, Washington DC, Bridgeport CT, New Haven CT, Bronx NY, San Mateo County (Bay Area) CA, Boston MA, Manhattan NY, San Francisco CA, White Plains NY, Napa CA, and San Luis Obispo CA. There's an obvious bias toward cities with academic centers and/or places where white collar workers like to live, although the last two locations (at least) also have large state psychiatric hospitals.

High Altitude Psychosis: A New Medical Entity?

Cross-posted at the MDK10Outside running and climbing blog.

A new paper breaks down cases of acute mountain sickness into several categories, including isolated psychosis with no evidence of cerebral edema (a quarter of cases!) Psychosis was more associated with accidents than the other subgroups, not surprising in retrospect. These cases were all taken from above 3500m/11,700'. It's always interesting that humans, and life on Earth generally, can tolerate some amazing extremes, but when the partial pressure of O2 drops a little bit, everything breaks.

Neuropsychiatric Diseases Cause Disproportionate Suffering

I've been poring over disability adjusted life-year statistics for the U.S. One of the things that made me choose psychiatry was that there are a lot of diseases that cause horrendous suffering, and one of the horrendous things about it is that this is suffering that can last a lifetime; they're not directly fatal illnesses in the same way that cancer or heart disease are. This highlights the conflict in medicine between decreasing suffering, and decreasing death. It's underappreciated by many people (including, in my experience, physicians) that these are not the same thing; that in fact there are many times when avoiding one can lead to the other, and vice versa. (One way to think of the job of a physician is to protect and extend the possibility of positive future experience.)

Disability-adjusted life years is the sum of years lived with disability (YLWD) and years of life lost (YLL) due to the disease. Granted, living with disease A for 10 years is likely to cause different suffering than disease B over the same time, but this gives us an idea. And the statistics are given in time per person across the population. Consequently if a disease causes lots of disability but is rare, it will have a lower number than another which causes less disability but is very common.

Some points that emerge from inspecting the data:

1) If you look at the ratio of YLWD to YLL, you can see which diseases kill quickly without much suffering (i.e. lots of people die from it but not many years lived with disability). On the other hand, if you want to focus on diseases that cause disproportionate suffering, you look for diseases with a high disability years to life lost ratio. In decreasing order, the diseases out of the top 50 that have the highest disability years:life lost ratio are: major depressive disorder, bipolar disorder, back pain, anxiety disorders, schizophrenia, alcohol use disorder, and drug abuse, COPD. One quirk is that suicide is listed separately and depression, bipolar and a few others have no stats for years lost, and suicide is how people die from depression and bipolar. So, if you make the simplifying assumption that suicide and MDD have a 1:1 correlation, i.e. everyone who dies from depression dies from suicide and everyone who commits suicide does so out of depression, the list doesn't change that much (now, bipolar disorder, back pain, anxiety disorder, schizophrenia, MDD, alcohol, drugs, COPD.)

The trend here toward neuropsychiatric disorders is clear.

2) Comparing the genders, it's unsurprising to see that women fare better than men. What's more, women's outcomes have improved more over the period 1990-2010, in conditions relating to behavioral risk-taking and impulse control - e.g., road injuries and drug use.

3) Embarrassingly, years per population lived with disability for schizophrenia, dysthymia nad bipolar are all essentially flat for this 20 year period. That's bad. That is not the case for most other major diseases.

4) The rise in death and disability over this period from addiction remains staggering. For added irony, a huge proportion (possibly the majority?) of this represents prescription drug abuse. This represents a major, major policy failure on the part of drug enforcement agencies - you know, the ones that have marijuana scheduled as more dangerous than synthetic opioids. The agencys' position must be: hey, people are suffering and dying, but it's a-okay as long as it's not from street drugs!

The Mortality of Aircraft Wheel-Well Stowaways

Cross-posted to my outdoors blog.

The FAA gives a report of 11 known stowaway incidents from 1947-1993.

Of these 11, 6 died. 2 of them had definitely frozen to death. 3 more fell after the plane made it to cruising altitude, and could have frozen to death. Another fell on takeoff. This means that you have a 55% chance of dying if you attempt this, and if you die the chance is 33-87% that you will freeze to death.

Of course it's likely that other fatalities occurred but were not discovered because the plane was over water or the body landed in an unpopulated area; it is also likely that people stowed away and were not discovered, so it's hard to say which way the sample is biased.

The mechanism cited as probable pathway to fatal hypothermia at altitude seems very likely to be the same one that explains the strange behavior of high altitude mountain climbers who succumb to a similar fate, and are found having taken off most or all of their layers. Under conditions of low ambient O2, the hypothalamus becomes hypoxic and can longer thermoregulate. In climbers, their frontal lobes are hypoperfused, and they feel hot and can't reason themselves out of/inhibit themselves from taking their clothes off in the middle of a glaciated mountain. Stowaways are crammed in and can't move anyway.

Management: don't be in a plane at cruising altitude outside a warmed and pressurized cabin.

Is Science Self-Correcting? Not Necessarily

Steven Hsu blogs a 2012 paper by John Ioannidis, the meta-analysis and replication guru who has become famous by identifying the statistical skeleton's in medicine's closet. Improving this is critical not only for medical science's ability to get results, but also in terms of science's credibility in the eyes of the public. This latter consideration has never been so critically important as now.

Excerpted from the abstract:
...self-correction does not always happen to scientific evidence by default....History suggests that major catastrophes in scientific credibility are unfortunately possible...Careful evaluation of the current status of credibility of various scientific fields is important in order to understand any credibility deficits and how one could obtain and establish more trustworthy results. Efficient and unbiased replication mechanisms are essential for maintaining high levels of scientific credibility...In the absence of replication efforts, one is left with unconfirmed (genuine) discoveries and unchallenged fallacies. In several fields of investigation, including many areas of psychological science, perpetuated and unchallenged fallacies may comprise the majority of the circulating evidence.
