Why do some parents refuse to vaccinate their children? Why do some keep guns at home, despite scientific evidence of risk to their family members? And why do people use antibiotics for illnesses they cannot possibly alleviate? When it comes to health, many people insist that science is wrong, that the evidence is incomplete, and that unidentified hazards lurk to harm us. In Denying to the Grave, Gorman and Gorman explore the psychology of health science denial. Using several examples of such denial as test cases, they propose seven key principles that may lead individuals to reject accepted health-related wisdom: the charismatic leader; fear of complexity; confirmation bias and the internet; isolation and marginalization; fear of corporate and government conspiracies; filling the ignorance gap; and the nature of risk prediction. The authors argue that the health sciences are especially vulnerable to our innate resistance to integrate new concepts with pre-existing beliefs. This psychological difficulty of incorporating new information is on the cutting edge of neuroscience research; scientists have identified brain responses to new information. This book explores risk theory and how people make decisions about what is best for them, in an effort to better understand how people think when faced with health decisions. Denying to the Grave points the way to a new understanding of how science should be conveyed to the public in order to save lives with existing knowledge and technology.
