Comments on Richard Jeffrey

Abstract

In this commentary, after first summarizing the three major theses of Jeffrey's paper ‘Probability and Falsification: Critique of the Popper Program’, and sketching out what I take to be his central argument, I criticize Jeffrey on two grounds. The first is that he has failed to explain why his version of Bayesianism provides us with better theories upon which to make decisions; the second is that he has offered a theory about decision-making that by-passes the important question: How can we make more rational decisions?
