Do children have “Bayesian intuitions”, so the ability to correctly determine posterior probabilities without knowing Bayes theorem?
Central hypothesis: Bayesian thinking does not depend primarily on abstract mathematics, but rather on the alignment between cognitive abilities and the way the problem is framed.
Children are capable of Bayesian thinking Even second graders can solve: ~22–32% of the problems correctly using icon arrays Fourth graders: ~50–60% correct
Surprising result: Dyscalculia ~50% correct using icon arrays → similar performance to typical…
