I took the survey and I agree with some other comments about the difficulty of assigning probabilities to distant events. I decided to just round to either 0 or 1% for a few things. I hope "0" won't be interpreted as literally zero.

Something bugs me about the IQ question. It's easy to call sour grapes on those complaining about that metric but it seems like such a poor proxy for what matters, namely, making awesome stuff happen. Not denying a correlation, just that I think we can do much better. Even income in dollars might be a better proxy despite the obvious problems with that.
