The expected value of defecting is 4p/(p + 4(1-p), to within one part in the number of survey takers. Whether or not you defect makes no difference as to the proportion of people who defect.
Unless you’re using timeless decision theory, if I understand TDT correctly (which I very well might not). In that case, the calculations by Zack show the amount of causal entanglement for which cooperation is a good choice. That is, P(others cooperate | I cooperate) and P(others defect | I defect) should be more than 0.8 for cooperation to be a good idea.
I do not think my decisions have that level of causal entanglement with other humans, so I defected.
Though, I just realized, I should have been basing my decision on my entanglement with lesswrong survey takers, which is probably substantially higher. Oh well.

I defected for the same reasons as you. We’re entangled! Reading the responses of the other survey takers I think it’s clear that very few people are entangled with us, so we did indeed make the right choice!
Yeah, and the math is a little different, three entangled decision makers for each cooperate-bot you can defect against (the number of defectors don’t matter, surprisingly). You get three extra chances to get the money generously donated to the pool by the cooperate bots by defecting, compared to causing a certain number of people to help you make the pool even larger.

Nevermind, you already covered this, though in a different fashion.
