Is it that crazy to expect that a moderator remove posts like this? I don't mind that the quality is not very good, but the inclusion of racial slurs should make it over the line.

At this moment, the post is at -19. That is moderation removing it, round these parts.

I thought it was a nice illustration of the distinction between map and territory, or between different maps of the same territory. In other words, JFK and the speaker's uncle were very close together by a certain map, but that doesn't mean they were very similar in real life.

After reading Contrafactus, a friend said to me: "My uncle was almost President of the U.S.!"

"Really?" I said.

"Sure," he replied, "he was skipper of the PT 108." (John F. Kennedy was skipper of the PT 109).

It is a good quote in general, but not quite a rationality quote.

"I remember reading of a competition for a paper on resolution of singularities of surface; Castelnuovo and Enriques were in the committee. Beppo Levi presented his famous paper on the resolution of singularities for surfaces.

Enriques asked him for a couple of examples and was convinced; Castelnuovo was not. The discussion got heated. Enriques exclaimed 'I am ready to cut off my head if this does not work', and Castelnuovo replied 'I don't think that would prove it either.'"

Of course, if bad proofs lead to heads being cut off, then there would probably be fewer bad proofs. (I take it the point here is not that Castelnuovo had any doubts about whether Enriques was being honest about believing the result or had come to his belief on flimsy grounds (which is usually not something one can take for granted...), but that he understood this and was interested in finding an explicit formal proof of the result.)

I think adding the author name in addition to "mathoverflow" would make sense.

Amusing post, thanks. It seems clear that life in advanced countries is indeed much worse than it could possibly be, and that failures to plan and cooperate are at least partly to blame. On the other hand, life is also much, much better than it could be (and was for most people in history), and I fully expect that it will continue to improve in the future. Maybe at some point we will be so rich, and coordinate so well, that some of your suggestions become commonplace.

Remember that programs will not even be tested unless there are good reasons to expect improvement over current protocol. Most programs that are explicitly considered are worse than those that are tested, and most possible programs are worse than those that are explicitly considered. Therefore we can expect that far, far fewer than ten percent of possible programs would yield significant improvements.

That is true. However, there is a second filtering process, after filtering by experts; and that is what I will refer to as filtering by experiment (i.e. we'll try this, and if it works we keep doing it, and if it doesn't we don't). Evolution is basically a mix of random mutation and filtering by experiment, and it shows that, given enough time, such a filter can be astonishingly effective. (That time can be drastically reduced by adding another filter - such as filtering-by-experts - before the filtering-by-experiment step) The one-to-two percent expectation that I had was a subconscious expectation of the comparison of the effectiveness of the filtering-by-experts in comparison to the filtering-by-experiment over time. Investigating my reasoning more thoroughly, I think that what I had failed to appreciate is probably that there really hasn't been enough time for filtering-by-experiment to have as drastic an effect as I'd assumed; societies change enough over time that what was a good idea a thousand years ago is probably not going to be a good idea now. (Added to this, it likely takes more than a month to see whether such a social program actually is effective or not; so there hasn't really been time for all that many consecutive experiments, and there hasn't really been a properly designed worldwide experimental test model, either).

Why not submit this as a comment on the prior post?

Because it's a point that stands on its own?

His claim, to my understanding, is that the first theory completely explains the interaction between minorities and liberal politicians.

I have read fairly many blog entries similar to this one, and to my recollection all were written by women.

Using words like this to describe ideas you don't like seems distasteful, and in fact similar to what the blogger was originally complaining about.

pgbh70

Consider these two theories:

Liberal politicians promote the well-being of minority groups because they want their votes. This constitutes a naked power grab.

Minority groups vote for liberal politicians because they expect them to promote their well-being. This constitutes democracy working as intended.

How would you tell which of these theories is true?

4JTHM
I have said nothing of the left promoting the well-being of minorities, and I have said nothing of why minorities support the left. I have said that the left tries to place left-leaning demographics in positions of power and influence (which is not always the same thing as actually helping those demographics, although helping them may be a side effect), and that leftists try to populate their social circles with those same demographics. Obviously, the right tries to place right-leaning demographics in positions of power and influence as well. For that matter, anyone who identifies with faction X tries to place likely X-ists in positions of power and influence. However, an attempt to do such a thing rarely feels like a power grab from the inside, regardless of your political orientation. Inside the mind of a leftist, a power grab of this form feels like promoting the noble cause of diversity.

in what way are those theories exclusive of each other?

Perhaps this is obvious already, but the positions people explicitly endorse on surveys are not necessarily those they implicitly endorse in blog comments.

Anyone want to set up an implicit association test for LW?

Also, people are free to interpret blog comments as it suits their goals.

You insist that there is something a machine cannot do. If you will tell me precisely what it is that a machine cannot do, then I can always make a machine which will do just that!

Sure other survey-takers may be roughly as rational as you, but that doesn't mean they're likely to do something as specific as precommitting to cooperation on prisoner's dilemmas.

Took the survey.

I chose to defect. Defecting maximizes the expected payoff for me personally, and the expected overall payoff isn't affected by my decision since Yvain just keeps whatever money isn't claimed.

An interesting variant would have been for Yvain to throw away whatever money was lost due to defections, or donate it to some organization most don't like. In that case I would probably have cooperated.
