In their postscript, M. R. Dougherty, A. M. Franco-Watkins, and R. Thomas (see record 2008-00265-011) asserted that models of fast and frugal heuristics have been vaguely specified. We strongly reject this claim. The computational models of search, stopping, and decision rules allow for precise predictions. In fact, many researchers have tested under which conditions people follow which heuristic, compared the predictions of heuristics to those of rational models, and studied the ecological rationality of different heuristics through statistical analysis and computer simulation. Dougherty et al also argued that the recognition heuristic might be vague because "to derive predictions based on the recognition heuristic, one needs to instantiate it at the level of a recognition memory model, as has been done by Pleskac (2007) and Schooler and Hertwig (2005)" (p. 213). We would like to mention that this work is in fact from our research group: Schooler and Hertwig's (2005) article is from our lab at the Max Planck Institute, and Pleskac worked in Hertwig's lab while he wrote his recognition article. We wish that Dougherty et al had instead dealt at greater length with the fundamental questions that arise in their postscript. (PsycINFO Database Record (c) 2008 APA, all rights reserved)
