--- - |2 Belief revision can occur at multiple levels of abstraction, including lower‐level and higher‐order beliefs. It remains unclear, however, how conflicting evidence interacts with prior beliefs to encourage higher‐order belief revision. This study explores how 4‐ and 5‐year‐olds (N = 96) respond to evidence that directly conflicts with their causal higher‐order beliefs. When shown a single event that directly violated a strongly supported prior belief, preschoolers largely maintained their initial higher‐order belief. However, when the prior belief was more weakly supported and the counterevidence was stronger, children changed their minds. These findings indicate that young children can revise their higher‐order beliefs and, furthermore, do so depending on the strength of both the evidence and their prior beliefs. - Child Development, EarlyView.
