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!

In that case, I pre-commit that if I win, I'll spend it on something leisure-related or some treat that I otherwise wouldn't be able to justify the money to purchase.
I co-operated; I'd already committed myself to co-operating on any Prisoner's Dilemma involving people I believed to be rational. I'd like to say it was easy, but I did have to think about it. However, I stuck to my guns and obeyed the original logic that got me to pre-commit in the first place.
If I assume other people are about as rational as me, than a substantial majority of people should think similarly to me. That means that if I decide that everyone else will co-operate and thus I can defect, there's a good chance other people will come to the same conclusion as well. The best way to go about it is to pre-commit to co-operation, and hope that other rational people will do the same.
Thanks for the chance to test my beliefs with actual stakes on the line :)
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.

Since it has suddenly become relevant, here are two results from this year's survey (data still being collected):
When asked to rate feminism on a scale of 1 (very unfavorable) to 5 (very favorable), the most common answer was 5 and the least common answer was 1. The mean answer was 3.82, and the median answer was 4.
When asked to rate the social justice movement on a scale of 1 (very unfavorable) to 5 (very favorable), the most common answer was 5 and the least common answer was 1. The mean answer was 3.61, and the median answer was 4.
In Crowder-Meyer (2007), women asked to rate their favorability of feminism on a 1 to 100 scale averaged 52.5, which on my 1 to 5 scale corresponds to a 3.1. So the average Less Wronger is about 33% more favorably disposed towards the feminist movement than the average woman (who herself is slightly more favorably disposed than the average man).
I can't find a similar comparison question for social justice favorability, but I expect such a comparison would turn out the same way.
If this surprises you, update your model.
Perhaps this is obvious already, but the positions people explicitly endorse on surveys are not necessarily those they implicitly endorse in blog comments.
