The Internet and other media can provide both a deep and accurate understanding of science and distort it. It's all about the evidence base. For example, when we take a medicine, we are confident that it is effective. When using cosmetics, we are sure that they are safe. But evidence is not always irrefutable; it can be random, groundless and unreliable. Joe Schwartz is a chemical scientist who talks in his book about the mechanisms of instilling pseudoscientific ideas. He tries to explain the pros and cons of various advances in chemistry, describes methods for testing the safety of a particular invention, be it genetic engineering or pesticides. Let's not let ourselves be deceived!
