Carl Shulman decided to join SingInst, so they can't be too crazy. :) Seriously, what's your explanation for why he seems to think SingInst is worth supporting but you don't (at least not yet)?

Far be it from me to suggest that Carl Shulman suffers from the frailties, biases and tendency to respond incentives prevalent amongst his fellow humans but didn't Carl Shulman also marry one of SingInst's most prominent researchers during the same time period that you referenced? That's the sort of thing that tends to influence human behavior.
