The domain specificity and generality of mental contamination: Accuracy and projection in judgments of mental content.

In this study we examined individual differences across two tasks requiring people to judge the mental contents of the minds of other people - an opinion prediction task and a knowledge prediction task. The tendency to overproject one's own mental contents in both of these tasks has been interpreted as an instance of mental contamination by Wilson and Brekke (1994). Results demonstrate no domain generality in the process of projecting one's own internal states onto predictions about the internal states of others.
