Crupi V. and Tentori K., Noisy probability judgment, the conjunction fallacy, and rationality: Comment on Costello and Watts (2014), Psychological Review, 123 (2016): 97-102.
Abstract. According to Costello and Watts (2014), probability theory can account for key findings in human judgment research provided that random noise is embedded in the model. We concur with a number of Costello and Watts’s remarks, but challenge the empirical adequacy of their model in one of their key illustrations (the conjunction fallacy) on the basis of recent experimental findings. We also discuss how our argument bears on heuristic and rational thinking.
