I wouldn't press the button, though I had to think a bit longer about the "erase from memory" part.
It reminds me of what Eliezer often says about Friendly AI: "If you offered Gandhi a pill that would make gandhi a murderer, gandhi would refuse to take it."
I would also refuse to do it even if my memory could be erased. Somehow, I don't feel it's really relevant, because when I'm considering wether to do it or not, I'm not even thinking about any guilt I might feel, I'm mostly repulsed by torture in general and imagining myself in the place of the person to be tortured.
I don't think I would have any particular problem with murder for an adequate reason, and I wouldn't take a "murder pill". A stupid illustration - though I don't remember seeing this phrase before and I've been following OB from the first post.
What do you believe that most people on this site don't?
I'm especially looking for things that you wouldn't even mention if someone wasn't explicitly asking for them. Stuff you're not even comfortable writing under your own name. Making a one-shot account here is very easy, go ahead and do that if you don't want to tarnish your image.
I think a big problem with a "community" dedicated to being less wrong is that it will make people more concerned about APPEARING less wrong. The biggest part of my intellectual journey so far has been the acquisition of new and startling knowledge, and that knowledge doesn't seem likely to turn up here in the conditions that currently exist.
So please, tell me the crazy things you're otherwise afraid to say. I want to know them, because they might be true.
