A taxonomy of these public responses is apparent: relief (as predicted by the authors of the article) that they did nothing to give themselves cancer, skepticism about the author’s motives, doubt about the accuracy of the science, a belief that the science must be wrong because cancer cannot be random, and anguish about their cancer being deprived of meaning. The last 2 responses often appear together.
