This editorial musing has been stimulated by two very thought-provoking articles. The first, by Larry Dossey (2011) discusses the confident but ignorant responses of scientists who trashed research showing that university students could make predictions about the future, such as which of two computer windows would be programmed by an automated system to display an erotic picture. The second, by Chris Mooney (Web reference), considers fascinating data showing that the more educated Republicans were, the more likely they were to reject scientific evidence for global warming. Following a discussion of these articles, I consider several important conclusions from these observations about how people form and hold onto their opinions. This is a vital issue in a world that is threatened by humanitys suicidal and homicidal behaviors, and seems unable to alter its course towards and killing every living being on our planet.
