QUOTE OF THE DAY....From Robin Hanson, on the source of human disputation:
We disagree because we explain our own conclusions via detailed context (e.g., arguments, analysis, and evidence), and others' conclusions via coarse stable traits (e.g., demographics, interests, biases). While we know abstractly that we also have stable relevant traits, and they have detailed context, we simply assume we have taken that into account, when we have in fact done no such thing.
There's more to disagreement than this, of course, but still. There's probably more truth to this than most of us would like to admit.
