| summary | In choice blindness experiments people typically answer a series of questions and are then asked to justify these answers. However, some of these answers have been manipulated so that the answers that participants are asked to justify are in fact the opposite of their actual answers. Most people do not detect these inversions and happily justify the answer that they believe to be theirs. I will briefly review some of this literature to show that it offers the best demonstration to date of the myside bias, the tendency to find arguments for one's side rather than against it (also know, somewhat improperly, as the confirmation bias). I will then present the results of new experiments conducted with Emmanuel Trouche and Petter Johansson that used the same paradigm to demonstrate two other biases: asymmetric argument evaluation -- people are much more lenient towards their own arguments than towards others' arguments -- and egocentric discounting -- people have a fundamental bias to favor their own opinion when it clashes with someone else's. |
