QUOTE : Do people know which risks lead to many deaths and which risks lead to few?” the legal scholar Cass Sunstein asks. “They do not. In fact, they make huge blunders.” Sunstein draws this observation from the work of Paul Slovic, author of The Perception of Risk. In a study that invited people to compare various causes of death, Slovic found that people tended to believe that accidents cause more deaths than disease and that homicide causes more deaths than suicide, when the opposite is true in both cases. In another study, people significantly overestimated the fatality rates of highly publicized or dramatic dangers like cancer or tornadoes. One could interpret this, as Sunstein does, to mean that most people are just wrong about risk. But risk perception may not be about quantifiable risk so much as it is about immeasurable fear. Our fears are informed by history and economics, by social power and stigma, by myths and nightmares. And as with other strongly held beliefs, our fears are dear to us. When we encounter information that contradicts our beliefs, as Slovic found in one of his studies, we tend to doubt the information, not ourselves.
