Abstract

Barbey & Sloman (B&S) conclude that natural frequency theorists have raised a fundamental question: What are the conditions that compel individuals to reason extensionally? We argue that word problems asking for a numerical judgment used by these theorists cannot answer this question. We present evidence that nonverbal tasks can elicit correct intuitions of posterior probability even in preschoolers.
