Stanovich & West (S&W) are wrong to think that all “reject-the-norm” theorists simply wish to reduce the normative/descriptive gap. They have misunderstood Issac Levi's reasons for rejecting Tversky and Kahneman's normative assumptions in the “base-rate” experiments. In their discussion of the taxicab experiment, (S&W) erroneously claim that subjects' responses indicate whether they have reasoned in accordance with Bayesian principles or not.
