What would you do if blood glucose theory of willpower was true?

9 taw 22 March 2010 08:18PM

There's considerable amount of evidence that willpower is severely diminished if blood glucose get down, and this effect is not limited to humans. And a small sugary drink at the right time is enough to restore it.

We're talking really small numbers. Total blood glucose of a healthy adult is about 5g and it varies within fairly limited range. Then there's maybe 45g in total body waters. Then there's about 100g of glycogen in liver, plus yet larger amount in muscles and other organs, but which doesn't seem to take part in sugar level regulation. For comparison a small can of coke contains 33g - a really small amounts at appropriate times can make a big difference.

This leads to two issues. First, is blood glucose a good explanation for willpower deficiency and therefore akrasia? I'd say there's significant amount of evidence that some effect exists, but is it really the most important factor? Humans are complicated, science knows very little about how we work, and probably half of what it "knows" is false or at best only half-true. Caution is definitely warranted.

And the second issue - if this theory was true - and by manipulating blood glucose levels you could achieve far greater willpower whenever you wanted, what would you do? It seems that exploiting it isn't that easy, and I'd love to hear if any of you tried it before.

Improving The Akrasia Hypothesis

69 pjeby 26 February 2010 08:45PM

Abstract: This article proposes a hypothesis that effective anti-akrasia methods operate by reducing or eliminating the activation of conflicting voluntary motor programs at the time the user's desired action is to be carried out, or by reducing or eliminating the negative effects of managing the conflict.  This hypothesis is consistent with the notion of "ego depletion" (willpower burnout) being driven by the need to consciously manage conflicting motor programs.  It also supports a straightforward explanation of why different individuals will fare better with some anti-akrasia methods than others, and provides a framework for both classifying existing methods, and generating new ones.  Finally, it demonstrates why no single technique can be a panacea, and shows how the common problems of certain methods shape the form of both the self-help industry, and most people's experiences with it.

The Hypothesis

Recently, orthonormal posted an Akrasia Tactics Review, collecting data from LessWrong members on their results using different anti-akrasia techniques.  And although I couldn't quite put my finger on it at first, something about the review (and the discussion around it) was bothering me.

See, I've never been fond of the idea that "different things work for different people".  As a predictive hypothesis, after all, this is only slightly more useful than saying "a wizard did it".  It says nothing about how (or why) different things work, and therefore gives you no basis to select which different things might work for which different people.

For that reason, it kind of bugs me whenever I see discussion and advocacy of "different things", independent of any framework for classifying those things in a way that would help "different people" select or design the "different things" that would "work for" them.  (In fact, this is a pretty big factor in why I'm a self-help writer/speaker in the first place!)

So in this post, I want to share two slightly better working hypotheses for akrasia technique classification than "different things work for different people":

Akrasia Tactics Review

56 orthonormal 21 February 2010 04:25AM

I recently had occasion to review some of the akrasia tricks I've found on Less Wrong, and it occurred to me that there's probably quite a lot of others who've tried them as well.  Perhaps it's a good idea to organize the experiences of a couple dozen procrastinating rationalists?

Therefore, I'll aggregate any such data you provide in the comments, according to the following scheme:

  1. Note which trick you've tried.  If it's something that's not yet on the list below, please provide a link and I'll add it; if there's not a link for it anywhere, you can describe it in your comment and I'll link that.
  2. Give your experience with it a score from -10 to +10 (0 if it didn't change the status quo, 10 if it ended your akrasia problems forever with no side effects, negative scores if it actually made your life worse, -10 if it nearly killed you); if you don't do so, I'll suggest a score for you based on what else you say.
  3. Describe your experience with it, including any significant side effects.

Every so often, I'll combine all the data back into the main post, listing average scores, sample size and common effects for each technique.  Ready?

Study: Making decisions makes you tired

Making your own decisions makes you procrastinate more and quit sooner than when you're following orders:

Key quote:

Making choices led to reduced self-control (i.e., less physical stamina, reduced persistence in the face of failure, more procrastination, and less quality and quantity of arithmetic calculations). A field study then found that reduced self-control was predicted by shoppers' self-reported degree of previous active decision making. Further studies suggested that choosing is more depleting than merely deliberating and forming preferences about options and more depleting than implementing choices made by someone else and that anticipating the choice task as enjoyable can reduce the depleting effect for the first choices but not for many choices.

Self control may be contagious

Just saw this article on reddit and thought it would be relevant here: Self Control is Contagious, Study Finds

Apparently seeing other people exhibit self control or even just thinking of them tends to increase (or decrease if observing poor self control) one's own self control.

Case study: Melatonin

21 gwern 07 January 2010 06:24PM

I discuss melatonin's effects on sleep & its safety; I segue into the general benefits of sleep and the severely disrupted sleep of the modern Western world, the cost of melatonin use and the benefit (eg. enforcing regular bedtimes), followed by a basic cost-benefit analysis of melatonin concluding that the net profit is large enough to be worth giving it a try barring unusual conditions or very pessimistic safety estimates.

Are wireheads happy?

Related to: Utilons vs. Hedons, Would Your Real Preferences Please Stand Up

And I don't mean that question in the semantic "but what is happiness?" sense, or in the deep philosophical "but can anyone not facing struggle and adversity truly be happy?" sense. I mean it in the totally literal sense. Are wireheads having fun?

They look like they are. People and animals connected to wireheading devices get upset when the wireheading is taken away and will do anything to get it back. And it's electricity shot directly into the reward center of the brain. What's not to like?

Only now neuroscientists are starting to recognize a difference between "reward" and "pleasure", or call it "wanting" and "liking". The two are usually closely correlated. You want something, you get it, then you feel happy. The simple principle behind our entire consumer culture. But do neuroscience and our own experience really support that?

Anti-Akrasia Technique: Structured Procrastination

51 patrissimo 12 November 2009 07:35PM

This idea has been mentioned in several comments, but it deserves a top-level post.  From an ancient, ancient web article (1995!), Stanford philosophy professor John Perry writes:

I have been intending to write this essay for months. Why am I finally doing it? Because I finally found some uncommitted time? Wrong. I have papers to grade, textbook orders to fill out, an NSF proposal to referee, dissertation drafts to read. I am working on this essay as a way of not doing all of those things. This is the essence of what I call structured procrastination, an amazing strategy I have discovered that converts procrastinators into effective human beings, respected and admired for all that they can accomplish and the good use they make of time. All procrastinators put off things they have to do. Structured procrastination is the art of making this bad trait work for you. The key idea is that procrastinating does not mean doing absolutely nothing. Procrastinators seldom do absolutely nothing; they do marginally useful things, like gardening or sharpening pencils or making a diagram of how they will reorganize their files when they get around to it. Why does the procrastinator do these things? Because they are a way of not doing something more important. If all the procrastinator had left to do was to sharpen some pencils, no force on earth could get him do it. However, the procrastinator can be motivated to do difficult, timely and important tasks, as long as these tasks are a way of not doing something more important.

The insightful observation that procrastinators fill their time with effort, not staring at the walls, gives rise to this form of akrasia aikido, where the urge to not do something is cleverly redirected into productivity.  If you can "waste time" by doing useful things, while feeling like you are avoiding doing the "real work", then you avoid depleting your limited supply of willpower (which happens when you force yourself to do something).

In other words, structured procrastination (SP) is an efficient use of this limited resource, because doing A in order to avoid doing B is easier than making yourself do A.  If A is something you want to get done, then the less willpower you can use to do it, the more you will be to accomplish.  This only works if A is something that you do want to get done - that's how SP differs from normal procrastination, of course.

Restraint Bias

16 Vladimir_Nesov 10 November 2009 05:23PM

Ed Yong over at Not Exactly Rocket Science has an article on a study demonstrating "restraint bias" (reference), which seems like an important thing to be aware of in fighting akrasia:

People who think they are more restrained are more likely to succumb to temptation

In a series of four experiments, Loran Nordgren from Northwestern University showed that people suffer from a "restraint bias", where they overestimate their ability to control their own impulses. Those who fall prey to this fallacy most strongly are more likely to dive into tempting situations. Smokers, for example, who are trying to quit, are more likely to put themselves in situations if they think they're invulnerable to temptation. As a result, they're more likely to relapse.

Thus, not only do people overestimate their abilities to carry out non-immediate plans (far-mode thinking, like in planning fallacy), but also the more confident ones turn out to be least able. This might have something to do with how public commitment may be counterproductive: once you've effectively signaled your intentions, the pressure to actually implement them fades away. Once you believe yourself to have asserted self-image of a person with good self-control, maintaining the actual self-control loses priority.

Biking Beyond Madness (link)

‘‘During race, I am going crazy, definitely,’’ he says, smiling in bemused despair. ‘‘I cannot explain why is that, but it is true.’’

The craziness is methodical, however, and Robic and his crew know its pattern by heart. Around Day 2 of a typical weeklong race, his speech goes staccato. By Day 3, he is belligerent and sometimes paranoid. His short-term memory vanishes, and he weeps uncontrollably. The last days are marked by hallucinations: bears, wolves and aliens prowl the roadside; asphalt cracks rearrange themselves into coded messages. Occasionally, Robic leaps from his bike to square off with shadowy figures that turn out to be mailboxes. In a 2004 race, he turned to see himself pursued by a howling band of black-bearded men on horseback.

‘‘Mujahedeen, shooting at me,’’ he explains. ‘‘So I ride faster.’’

This 2006 New York Times story is about Jure Robic, a Slovenian ultra long distance bicycler who goes seriously insane when he pushes himself far enough during the races. At the point he feels like dying out of fatigue he still has a major portion (estimated 50 % by his team) of his strength left. So he hands over control to his team and with their help, pushes himself into the realm of insanity and gives up control to the team:
