What a fascinating case of parallel evolution: As the cicada has a life cycle of 17 years (a prime number) to avoid predators with shorter life cycles, so too does the common or garden nerd choose clothes that are fashionable only once every 17 years, to minimize overlap with other, dangerous fashions.

But many poor/middle-class people also believe that they can never become rich (except for the lottery) because the only ways to become rich are crime, fraud, or inheritance. And this leads them to underestimate the value of hard work, education, and risk-taking.
The median rationalist will perform better than these cynics. But his average wealth will also be higher, assuming he accurately observes his chances at becoming succesful.
Wow—that’s pretty f-ed up right there.
This story, however, makes me understand your idea of “failed utopias” a lot better than when you just explained them. Empathy.
So I’ve turned on the tv to watch a debate on evolution and creationism on CNN (or Fox News). The creationists have sent an older, respectable-looking gentleman in a suit, bible in hand. The evolutionists have sent a scrappy-looking college kid in jeans, barely out of his diapers and studying something fancy-shmancy at the University of Liberal Professors, Berkeley.
A priori, whose side will I be on?
How many people will think: “Is this the best guy the evolutionists have to offer?”
Hi. I’ve made a few posts here and there, but have mostly been lurking lately.
I second that. Here in the LW/OB/sci-fi/atheism/cryonics/AI… community, many of us fit quite a few stereotypes. I’ll summarize them in one word that everybody understands: we’re all nerds*. This means our lives and personalities introduce many biases into our way of thinking, and these often preclude discussions about acting rationally in interpersonal situations such as sales, dating etc. because we don’t have much experience in these fields. Anything that bridges this gap would be extremely useful.
*this is not a value judgment. And not everybody conforms to this stereotype. I know, I know, but this is not the point. I’m talking averages here.
Another reason for honoring the sunk cost of the movie ticket (related to avoiding regret) is that you know yourself well enough to realize you often make mistakes. There are many irrational reasons why you would not want to see the movie after all. Maybe you’re unwilling to get up and go to the movie because you feel a little tired after eating too much. Maybe a friend who has already seen the movie discourages you to go, even though you know your tastes in movies don’t always match. Maybe you’re a little depressed and distracted by work/relationship/whatever problems. Etc.
For whatever reason, your past self chose to buy the ticket, and your present self does not want to see the movie. Your present self has more information. But this extra information is of dubious quality, and is not always relevant to the decision. But it still influences your state of mind, and you know that. How do you know which self is right? You don’t, until after you’ve seen the movie. The marginal costs, in terms of mental discomfort, of seeing the movie and not liking it, are usually smaller than the marginal benefit of staying home and thinking about what a great movie it could have been.
The reasoning behind this trivial example can easily be adapted to sunk cost choices in situations that do matter.
The sunk cost fallacy is easy to understand and to point out to others, but I caution against using it too often. The point of the fallacy is to show that only future costs and benefits matter when making a decision. This is true, but in reality those costs and benefits (and especially their probabilities) are hard to define. It is not clear whether the extra information that was received after ‘sinking’ the cost has an impact on the cost and benefit probabilities. You also know that, in any case, if the decision to sink the cost in the first place was the right one after all, the decision to continue is even more rational as a large part of the cost has already been spent. You can go see a movie for free that other people still have to pay for.
It sounds like your fellow students understood the concept of a guessing penalty, but did not realise that the guessing penalty was too low in this case. One approach to convince them might have been:
Assume you get −0.0001 points for guessing an incorrect answer. Obviously, you should answer every question, because the penalty for guessing is so low. Now, assume that the guessing penalty is −20 points. Again, you obviously shouldn’t guess. What would the penalty have to be where you’re indifferent between guessing and not guessing? Obviously, when the penalty is −1 point. You guess two answers, one is correct and the other not, and your expected score is 0. In this case the penalty is −0.5, which is closer to −0.0001 than to −20, therefore you should always guess.
NB At my university, multiple choice exams always feature four possible answers, and you lose .33 for guessing incorrectly. Every student understands this concept perfectly. If they had to take your exam, they would’ve guessed every single time. It’s strange to see that there are universities where the guessing penalty is not well calibrated. It seems like an elementary thing to do.
I read your comment and I immediately wanted to vote up Marshall’s original comment. After all, he’s the underdog being criticized and chased away by the founder and administrator of this blog.
In the end, I didn’t, probably for equally irrational reasons.
I know that the student would be studying a related field; that was not the point. I as a hypothetical viewer would not care what the grad student was studying, exactly, I would care that he was only a 20-year old graduate student still studying at a university (that I would assume to be populated with liberal professors).
“Winners don’t win by playing dumb.”
And that is why I don’t get this proposal. It is assumed that this college student would absolutely destroy the creationist debater and persuade the open-minded and objective audience through sheer, well, persuasiveness. But the audience, unless already completely in favor of evolution, is at least sympathetic to the creationist and interested in their views. This proposal would signal that this experienced debater and high-status leader of a movement is no more than a wet-behind-the-ears, unexperienced student. Doubting listeners would dismiss this fact out of hand and a priori; they will think it condescending to send someone like that to debate someone like this, which it is, to the creationist but especially to the audience. They will then attach less weight to any arguments, however persuasive, the student would make.
Biasing your audience against you before the debate has even started is not a viable tactic.
Seth godin has a few examples of sunk costs. I believe these examples better represent true sunk costs than some of the examples given here (such as the movie ticket).
For example, suppose you have paid 50 dollars for a Bruce Springsteen concert. You have searched long and hard for tickets this cheap. Suddenly, somebody offers you 500 dollars for the ticket. Do you sell it? The ticket is now worth $500 to you, and you would have never paid $500 for a ticket in the first place.
Voted up from −1 because I want you to clarify. Do you believe that bisexuality in women is ubiquitous, while not ubiquitous, but present in some men? Or that it is completely absent in men, but present though not ubiquitous in women? Or any other combination of absent, present or ubiquitous in either women or men?
Okay, but he’s clearly young. I don’t see how sending a low-status person to debate a high-status person could ever convince the adherents of the high-status person.
Yes, and if there was a utility lever that you could pull to gain utility, you would spend your entire life pulling the lever. But there isn’t. And you cannot teleport, nor will you be able to in the foreseeable future. So Alicorn will have to continue taking the burden of travel into account when deciding whether or not to visit a place he would like to have visited.
Your post definitely illustrates your point, by misleading otherwise well-informed LW readers for at least a few paragraphs.*
Therefore, I believe it’s a useful post. However, as you can see in the comments, the temptation to write lame follow-up jokes is just too big. Don’t expect too much serious discussion here.
*unless they were previously familiar with the joke, of course.
Those people died after ingesting impure DHMO, which is ‘watered down’ by relatively unharmful minerals, making it only fatal after ingesting large amounts. 100% pure, distilled DHMO is actually extremely dangerous even in small quantities, as it leeches essential nutrients from your body through a nefarious process called ‘reverse osmosis’.
[EDIT: this is actually not true, according to the wisdom of the interwebs. Thank you, extremely expensive European public school system, for filling my young impressionable mind with this untrue factoid. Nevertheless, the dangers and risks of DHMO ingestion remain poorly understood.]
I interpreted the last statement as follows:
IF you assign a probability higher than 10^(-8) to the hypothesis that you are in a holodeck
AND you win the lottery (which had a probabiltiy of 10^(-8) or thereabouts)
THEN you have good reason to believe you’re in a holodeck, because you’ve had such improbable good fortune.
Correct me if I’m wrong on this.
Not really. Think of Nozick’s experience machine. If you were to use the machine to simulate yourself in a situation extremely close to the center of the singularity, would you also give yourself the looks of Brad Pitt and the wealth of Bill Gates?
a) Would this not make the experience feel so ‘unreal’ that your simulated self would have trouble believing it’s not a simulation, and therefore not enjoy the simulation at all? In constructing the simulation, you need to define how many positive attributes you can give your simulated self before it realizes that its situation is so improbable that it must be a simulation. I’d use caution and not make my simulated self too ‘lucky.’
b) More importantly, you may believe that a) doesn’t apply, and that your simulated self would take the blue pill, and willingly choose to continue to live in the simulation. Even then, having great looks and great wealth would probably distract you from creating the singularity. All I’d care about is the singularity, and I’d design the simulation so that I have a comfortable, not too distracting life that would allow me to focus maximally on the singularity, and nothing else.
They emphasize the legs and the thighs, and create a more “female” body posture.
Actually, the trick worked, but the effects had worn off by the time you wrote this message, which is why you deny having your opinion on the AI issue completely reversed in a shocking aha-erlebnis, for a brief ten minutes at least. Remember to videotape yourself the next time.
