Abstract
We show that participants’ mean naïve probability estimates are consistent with each other, based on what would be predicted by Bayes theorem. Further, providing base-rates has a small but significant effect on conditional probability estimates, bringing estimates more in line with Bayesian posterior estimates based on these base-rates.
