ence, then it will be worthwhile to identify good problems, and even more worthwhile to discover the attributes that make them good problems. This discovery process is necessarily empirical, so we examine several challenge problems, beginning with Turing’s famous test, and more than a dozen attributes that challenge problems might have. We are led to a contrast between research strategies—the s...

In a hypothesis comparison task involving quantifiable evidence, we investigated whether judgments of relative probability were affected by gradual evidence accumulation and by making a series of revised ratings, rather than a single final one. Each trial of our task required participants to rate the probability that a focal hypothesis, rather than its alternative, was correct. We manipulated (...
