  on: Wel­come to Less Wrong! (7th thread, De­cem­ber 2014)

  I discovered lesswrong.com because someone left a printout of an article on the elliptical machine in my gym. I started reading it and have become hooked.

  I’m a formally uneducated computer expert. The lack of formal education makes me a bit insecure, so I obsess over improving my thinking through literature on cognitive dissonance and biases, such as books from the library and also sites like this.

  Nowadays I get paid to be a middle-manager at technology companies. Most of my career has been in Linux system administration as well as functional programming.

  I’m a bit of a health nut. I adopted a whole-food plant-based diet (the “China Study” diet) because it seems most well supported in the literature, although a broad consensus on the topic has not emerged. I base this decision in part on my trust of experts with titles after their names, since I’m too out of my element to read and interpret most of the literature on my own. At the same time I have a personal anecdote that this works well, so those two are enough to convince me for now.

  There are times when I find reading about rational thinking rather sobering. It’s clear that we were born with an irrational, “defective”, brain and that we would be so lucky if we could even make a small dent in improving our decision making. Improvements seem very hard to come by, I worry that all I’m really doing is learning to distrust my beliefs.

  So that’s a nutshell full. How’s everyone else? :)

  on: Your in­tu­itions are not magic

  The immediately available example supporting your article for me is the relationship between dietary cholesterol and blood cholesterol. There’s high general confusion around this health claim.

  What no doubt compounds the confusion on the issue is that intuitively you might infer that eating zero cholesterol should lower blood cholesterol, or that eating high cholesterol should raise blood cholesterol. Evidence shows this often happens, but not always. There are enough notable outliers that the claim has been defeated in the general mind because it doesn’t support the intuitive story.

  That is, vegans who eat almost no cholesterol containing foods, can have high blood cholesterol. On the flip side, surely everyone has heard of that friend of a friend who eats inf eggs a day and has low blood cholesterol.

  There’s a reasonably interesting story that fits the evidence for the claim that if dietary cholesterol then blood cholesterol, but the nonlinearity of the relationship and also the incidence of intuition defeating cases cloud the issue.

  Yes. I spent a lot of time reviewing critiques of The China Study (TCS), including Minger’s. At the end of it I came to the following conclusions.

  1. Nutrition science is extraordinarily nonlinear

  2. I’m definitely not qualified to deconstruct claims made about nutrition

  3. TCS critics don’t seem very qualified either, especially when compared to the qualifications of the people advancing TCS

  4. There’s no larger group of qualified people advancing a radically different approach

  So, those are my reasons. I admit they’re not very satisfying. I’m spoiled by fields where, once you grok the formal proof you can be highly confident that the claim is correct.

  No such luck with something as squishy as nutrition, it would seem.

  I’m skeptical this is a great strategy for topics in general.

  Nutrition, for example, doesn’t appear to be the kind of topic where you can just learn its axioms and build up an optimal human diet from first principles. It’s far too complicated.

  Instead you need substantial education, training, experience and access, as well as a community that can help you support and refine your ideas. You need to gather evidence, you need to learn how to determine the quality of the evidence you’ve gathered, and you need to propose reasonable stories that fit the evidence.

  Since I haven’t made health and nutrition my career most of these things will be hard or even impossible for me to come by. As such, my confidence in the quality of any amateur conclusions I come to must necessarily be low.

  So, the most reasonable thing for me to do is trust authorities when it comes to nutrition.

  on: Is there a ra­tio­nal­ist skill tree yet?

  Great request. Along a similar line, what about a decision tree for evaluating claims?

  1. Are you being asked to think about past decisions, prior beliefs, or intent? Take steps to rule out hindsight bias.

  2. Does the claim challenge prevailing beliefs, possibly alleging conspiracy? Consider confirmation bias.

  ...

  (sorry if this is a FAQ)

  on: Earn­ing to Give vs. Altru­is­tic Ca­reer Choice Revisited

  There’s a bit of a false dichotomy here between ‘earning to give’ and ‘altruistic career’. I’ll talk about one of them which we’ll need to go macro to see. I will also implicitly complain that ‘earning to give’ allows companies to deflect on charitable giving in a way that satisfies individual actors but may result in less charitable giving overall.

  Working on Wall Street and practicing an ‘earning to give’ plan may not be a great way to maximize giving to high-ROI aligned charities.

  I work at an HFT of order 1000 employees. The HFT itself makes no charitable donations. When employees ask about charity the HFT points at their large bonuses and says if a cause is important to you go ahead and donate your (huge) bonus to that cause. The HFT occasionally invites representatives from GiveWell and similar to come talk to us about pledging to donate a portion of our income to high-ROI charities. The bonuses can be big and if you do some multiplication you really can come away with the impression that you and your coworkers are collectively contributing enormous value to charity.

  Is this a fantasy though? I can’t know how everyone spends their bonuses but projecting from intimate discussions with my peer group has led me to believe that most employees, if they do donate, donate token amounts of $500-5000. Usually to more “name brand” causes like MSF or EFF. I’m aware of one person who donates their entire bonus to charity and a handful of others who have taken the GiveWell pledge.

  (Don’t take this as an endorsement of GiveWell or anything, I’m simply holding them up as a symbol of the idea)

  I don’t mean to overstate the progressiveness of the company either. There are also the more familiar Hollywood renditions of Wall Street employees who appear to spend their bonuses on sweet apartments and fancy cars before they’ve even been paid.

  Obviously this is anecdotal. I’m only describing a practice inside of one Wall Street firm. This may not be an accurate picture; it’s frowned upon to discuss compensation with one another so it’s hard to know the amounts at stake. There could be a handful of extremely high earners that secretly plow all of their wealth into high-ROI charities, which would more than make up for all of the modest earners who save their bonuses or take very nice holidays in the tropics.

  (btw, I’m not making an absolute value judgment on how people spend their bonuses, only speaking about how to maximize value to charity)

  Wait, why are we talking about what the entire company does when we’re trying to figure out what individual actors should do? Here’s why.

  All-in, if you can’t make a more valuable altruistic career choice it’s not strictly true that earning to give on Wall Street is the only reasonable alternative. If you could find an organization whose policy is to donate, say, 10% of all profits to charity, that number may be much larger than the discretionary charitable gifts made by employees at an equivalently sized Wall Street firm. If you’re concerned that the company with the 10% policy is donating to the wrong charities, you could consider joining that firm and campaigning to allocate more of the firm’s giving to charities aligned with GiveWell.

  on: The Im­por­tance of Sidekicks

  Kenzi said, approximately [I don’t remember her exact words]: “What if your aura of destiny didn’t have to be those things? What if you could be like…Samwise, from Lord of the Rings? You’re competent, but most importantly, you’re loyal to Frodo. You’re the reason that the hero succeeds.”

  In Australia, something about the way you interacted with people suggested to me that you help people in a completely free way, joyfully, because it fulfills you to serve those you care about, and not because you want something from them… I was able to relax around you, and ask for your support when I needed it while I worked on my classes. It was really lovely… The other surprising thing was that you seemed to act that way with everyone. You weren’t “on” all the time, but when you were, everybody around you got the benefit. I’d never recognized in anyone I’d met a more diffuse service impulse, like the whole human race might be your master. So I suddenly felt like I understood nurses and other people in similar service roles for the first time.

  Project this idea to community scale and you have a gift economy.

  Why should we listen to you and not, say, the Harvard School of Public Health ?

  That is, why do you think you did a better job of reading and interpreting the literature and publishing guidelines?

  Noted. To be clear, the question I’m asking is why is OP a more worthy authority than the rest?

  Why should we listen to OP and not follow, say, the UK’s NHS healthy living guidelines? I hope the answer is better than “because nobody at the NHS is a member of LW”

  Sorry for the confusion. I’m picking authorities at random and asking why I should trust you over them, not vouching for any authority in particular. Perhaps I should have asked more bluntly: who are you and why are you qualified to give us health advice?

  No offense. :)

  I am having a hard time finding places I disagree significantly with them.

  More a curiosity than anything: dairy isn’t represented at all on the HSPH’s “healthy eating plate” but is specifically highlighted in your section on nutrition. Why the discrepancy?

  After initial success but then several bouts of plantar fascitis, new mystery leg pain and a heaping helping of denial I’ve finally given on up the minimal shoes thing.

  I agree walking around in super comfortable shoes all the time probably makes us puny and weak, but I doubt paleolithic man walked and ran on hard city-grade pavement 50+ miles a week.

  Try to hack your body into feeling more relaxed so your scholarly zeal calms down a bit and lets your mind rest.

  I’ll tell you what works for me.

  1. Start dimming the lights as you approach bed-time. You can buy electric tea candles (as you may have seen in restaurants) to provide low lighting so you can still get around your home. The candle-like flickering of the light is pretty calming.

  2. Install f.lux (or its ilk) on any PC or mobile device with a screen.

  3. If you listen to music, make sure it’s relaxing. Playing nature sounds or whatever YT returns for “meditation music” works pretty well.

  4. Don’t underestimate olfactory senses. Buy an aroma diffuser and pick up some essential oils. Grapefruit or ginger scented mist can be seriously relaxing.

  5. Keep some kind of whimsical treatise next to your bed so you have an outlet for what should now be sleepy intellectual curiosity: Godel-Escher-Bach is perfect for this.

  Good luck! :)

  EDIT: Oh, also what about psychoactive stuff like coffee and alcohol? Coffee in the afternoons can cause tossing and turning at night even though the wakefulness benefits are long gone. Alcohol is considered a CNS depressant but it can still lead to some difficulty sleeping because of other related effects.

  Not if everything is reset back to the way it was!

  He doesn’t say that though. Perhaps he meant to imply that. Let’s suppose he did, what does the experiencing vs remembering self model say about that?

  You would start building memories. As you build them you’re servicing the experiencing self, and over the course of the vacation your remembering self can recall the things you did earlier in the vacation. Finally the vacation ends and time resets to before the vacation and it’s all gone, memories, sunburn. All of your new Facebook friends are strangers again.

  If this is the problem he meant to specify then I’m still confused. Isn’t this vacation model a microcosm of life? One day it ends, and everything is gone. Do you still bother living it? Is talking about a vacation that resets just less likely to trigger existential angst in the audience than asking people to think about why they bother living?

  So,

  1. you can have an amazingly beautiful night that you don’t remember the next day

  2. you can have a memory implanted that you had an amazingly beautiful night that never actually happened

  which do you choose?

  I like this because 1 has the benefit of being closer to the actual human experience.

  If I were Kahneman and I had posed that riddle, I would object that the entire point of the thought experiment is to consider the activity as being of no future utility whatsoever.

  Sorry, I don’t follow you. If you were Kahneman you would have posed the riddle differently? Or are you saying that I’m unfairly describing it?
