““The insult effect: Studies have shown that if you and another person are debating the merits of a particular idea and the other person suddenly insults you, you will instantly retreat further into your own position, and your conviction that the other person is wrong will intensify. (...) of course, your interlocutor's manners have nothing to do with how right or wrong he is. (...) This suggests an annoying but immovable fact of life; sometimes, disagreeable people are right. (p.151)””
