Information gain and decision-theoretic approaches to data selection: Response to Klauer (1999)

K. C. Klauer (1999) argued that a Bayesian decision-theoretic rational anal ysis of Wason's selection task is preferable to an information gain account (M. Oaksford & N. Chater, 1994) because it has a better normative justific ation and may provide a better fit with the empirical data. The authors arg ue that Klauer's proposal and their proposal are equally well justified fro m a normative perspective and that, where the predictions of the 2 approach es diverge, the existing empirical evidence is consistent with the informat ion gain approach. However, more empirical research is required to decide b etween these 2 accounts.
