CHURCHVILLE, VA—I can’t help but praise Michael Specter’s new book: Denialism: How Irrational Thinking Hinders Scientific Progress, Harms the Planet, and Threatens Our Lives. Specter warns that we live in a world where the leaders of African nations prefer to let their citizens starve to death rather than import genetically-modified food grains. Childhood vaccines have proven to be the most effective public health measure in history, yet people march on Washington to protest their use. Fifty years ago pharmaceutical companies were regarded as vital supports for our good health and lengthening life spans; now they are seen as callous corporate enemies of health and the environment.
