I'd be interested in people's opinions of how dire the real world consequences have to be before it's worthwhile debating dishonestly
I, for one, have the impression me that the more dire the consequences, the more important honesty in arguments becomes. So, I don't really get your dilemma.
What if you are Jewish and are trying to stop a Hitler from coming to power and the best means would be to spread a deliberate lie about him. Are you saying that the worse the outcome would be, the less likely you would be to lie?
Scott, known on LessWrong as Yvain, recently wrote a post complaining about an inaccurate rape statistic.
Arthur Chu, who is notable for winning money on Jeopardy recently, argued against Scott's stance that we should be honest in arguments in a comment thread on Jeff Kaufman's Facebook profile, which can be read here.
Scott just responded here, with a number of points relevant to the topic of rationalist communities.
I am interested in what LW thinks of this.
Obviously, at some point being polite in our arguments is silly. I'd be interested in people's opinions of how dire the real world consequences have to be before it's worthwhile debating dishonestly.
