摘要Widely discredited ideas nevertheless persist. Why do we fail to "unlearn"? We study one explanation: beliefs are resistant to retractions (the revoking of earlier information). Our experimental design allows us to identify updating from retractions - unlearning - and to compare it with updating from equivalent new information - learning. Across different kinds of retractions - for instance, those consistent or contradictory with the prior, or those occurring when prior beliefs are either extreme or moderate - subjects do not fully unlearn from retractions and update approximately one-third less from them than from equivalent new information. While we document a number of well-known biases in belief updating in our data, our results are inconsistent with any explanation that does not treat retractions as inherently different. Instead, our analysis suggests that retractions are harder to process, for instance, due to the intimate reliance on conditional reasoning.
