I'm worried by the amount of psychological trickery you have to do in order to make a donation. If you thought that making a large donation to SIAI was the right thing to do, why do you need to trick yourself?

Maybe it's a sign of my very weak understanding of human psychology and introspection (the kind of things I came to Less Wrong to learn), but this still is intuitively raising alarm bells to me.

But still, I'm glad you made a donation, even if you didn't donate with the mindset that I like. You still deserve some glowy feelings ...even if I don't think charity normatively should be about glowy feelings. I'm reminded of "Purchase Fuzzies and Uitlons Separately" here.
