The Curse of Knowledge in Reasoning About False Beliefs

Birch (2007) · Psychological Science · Read the paper

The paper shows that adults, like young children, make errors in reasoning about false beliefs when the measure is sensitive enough. Adults' own knowledge of an event's outcome compromised their ability to reason about what another person believed about that event, a curse-of-knowledge bias. The perceived plausibility of the event mediated how large the bias was. The authors discuss what this means for adults' and children's social cognition.
