I was recently reading a blog here, that referenced a paper done in 1999 by Baba Shiv and Alex Fedorikhin (Heart and Mind in Conflict: The Interplay of Affect and Cognition in Consumer Decision Making). In it, volunteers are asked to memorise short or long numbers and then asked to chose a snack as a reward. The snack is either fruit or cake. The actual paper seems to go into a lot of details that are irrelevent to the blog post, but doesn't actually seem to contradict anything the blog post says. The result seems to be that those with a higher cognitive load were far more likely to chose the cake than those who weren't.

I was wondering if anyone has read any further on this line of research? The actual experiment seems to imply that the connection between cognitive load and willpower may be an acute effect - possibly not lasting very long. The choice of snack is made seconds after memorising a number and while actively trying to keep the number in memory for short term recall a few minutes later. There doesn't seem to be anything about the effect on willpower minutes or hours later.

Does anyone know if the effect lasts longer than a few seconds? If so, I would be interested in whether this affect has been incorporated into any dieting strategies.

We'd better start pushing emotional buttons and twisting the mental knobs of people if we want to get something done. Starting with our own.

I looked for Information Diet in Lesswrong search, and found something amazing:

On Lukeprog's Q and A as the new executive director, he was asked:

What is your information diet like? (I mean other than when you engage in focused learning.) Do you regulate it, or do you just let it happen naturally?

By that I mean things like:

• Do you have a reading schedule (e.g. X hours daily)?
• Do you follow the news, or try to avoid information with a short shelf-life?
• Do you significantly limit yourself with certain materials (e.g. fun stuff) to focus on higher priorities?
• In the end, what is the makeup of the diet?
• Etc.

To which he responded:

• I do not regulate my information diet.
• I do not have a reading schedule.
• I do not follow the news.
• I haven't read fiction in years. This is not because I'm avoiding "fun stuff," but because my brain complains when I'm reading fiction. I can't even read HPMOR. I don't need to consciously "limit" my consumption of "fun stuff" because reading scientific review articles on subjects I'm researching and writing about is the fun stuff.
• What I'm trying to learn at this moment almost entirely dictates my reading habits.
• The only thing beyond this scope is my RSS feed, which I skim through in about 15 minutes per day.

Whatever was the case back then, I'll bet is not anymore. No one with assistants and such a workload should be let adrift like that.

Citizen: But Lukeprog's posts are obviously brilliant, his output is great, even very focused readers like Chalmers find Luke to be very bright.

Which doesn't tell much about what they would have been were he under a more stringent diet. Another reasonable suspicion is that he was not actually modelling himself correctly, since he obviously does have an information diet

The Information Diet Challenge is to set yourself an information diet, explicitly, and follow it for a week.  

Many ways of countering biases have been proposed here, but I haven't found a post dealing with this specific, very low hanging fruit one. 

If you want inspiration, Ferriss has some advice here.

... but that is not the Positive Information Diet yet...

Information diets are supposed to constrain not everything you intake, but only what you intake instrumentally. If you just love reading about tensors and fairy tales, don't include them in what you won't avoid. What matters is to know that you'll avoid trying to learn programming by reading a programmer's tweet feed, avoid becoming a top researcher in psychology by reading popular magazines on it, and avoid reading random feeds on Facebook that don't relate to your goals in appropriate ways.

General form: I will Avoid spending my time reading/commenting things of kind (A)(Avoid), because I know that to reach my set of goals (G), the most productive learning time is doing (P) (Positve/Productive). 

So here is an attempt:

(G): Interact fruitfully with people at Oxford

(A): Facebook feeds that are not by them; News of any kind; Emails I can Postpone; Gossip; Books/articles not on Evolution of Morals, enhancement, AI; Wikidrifting; Family meal small talk; SMBC; 9gag; Tropes .... and a bunch of other stuff I don't have time or patience to list.

(P): Google scholar on the intersection between my research topic and theirs. Reading their papers by day, watching their videos by night. Re-read what I might help them with that was read before, list topics per person, write what to say about each topic.

What is wrong with this attempt is that (A) ends up being a negative list. A list of what what I do not want to intake. Since possibilities are infinite, this will give me ridiculous cognitive load, and that is a problem. So here is simple solution, which I used for a food diet before, and worked great:  Name not what you cannot do, but what you are allowed to do. Way fewer bits, way easier to check! 

Food example: I'll eat only plants, lean fish and chicken, nuts, fruits, whole pasta, beans and Chai Lattes.

We are better at checking for category inclusion than exclusion. There are so many available categories to exclude from that we don't feel bad that we "forgot" to check for that one. Then after you let yourself indulge in a tiny one, a small one doesn't seem that bad, and snowball effect does the rest. We sneak in connotations to make categories smaller, so our actions stay safely outside the scope of prohibition. Theoretically, we could do the reverse, but it is psychologically much harder. Just try to convince yourself that beef is "lean chicken" to see it.

So let us forget completely about (A). There is no kind or class of kinds to avoid. there is only G and P, and now there is also T, the time during which P is in force, since escape valves might be necessary to avoid "screw that" all-or-nothing effects.

An Improved attempt:

G: Interact fruitfully with people in Oxford

P: Google scholar on the intersection between my research topic and theirs. Reading their papers by day, watching their videos by night. Re-read what I might help them with that was read before, list topics per person, write what to say about each topic. Only Facebook them. 

T: 02:00-23:59 daily.

This is only for "computer use", where I'm most likely to do the wrong thing.

Now there is a simple to check list of things I want to do, I could be doing, and I'll try to do until G arrives. I can only do those. If x doesn't belong, don't do it, that simple. I'm free from midnight to two to do whatever, thus I don't feel enslaved by my past self.  No heavy cognitive load is burning my willpower candle (Shawn Achor 2010) by trying set theory gimmicks to get me to do the wrong thing. 

So please, take the:

          Positive Information Diet Challenge

Write your G's (goals) P's (positives) and T's (times), and forget about your A's (Avoids)
