How does social learning affect stable false beliefs?
Rheza Budiono1 (), Catherine Hartley1, Todd Gureckis1; 1New York University
Learning traps are false beliefs that entrench themselves by discouraging the exploration required to correct them. In previous lab experiments, these learning traps have proven remarkably difficult to prevent. Here, we investigate whether learning traps remain stable in contexts in which both individual and social learning are possible. In two of our three experiments, we found that learners trapped by a false belief were significantly more likely to escape a learning trap when they were able to observe another decision-maker's choices (without observing their outcomes). However, social learning was not a panacea. Social learning was constrained by the challenge of inferring others' beliefs, and trapped learners struggled to learn from partners with sub-optimal decision rules, even when their partner's choices were informative. Collectively, these results suggest that while social learning can help overcome the limits of individual learning, learning from others comes with its own challenges and limitations.
