Summary

In the book String Theory and the Scientific Method,Richard Dawid describes a few of the many non-empirical arguments that motivate theoretical physicists’ confidence in a theory, taking string theory as case study. I argue that excessive reliance on non-empirical evidence compromises the reliability of science, and that precisely the case of string theory well illustrates this danger: Being Bayesian on positive hints, and Popperian when things go wrong, is not rational, but rather is blindness.
