It seems crazy to think that our very irrationality might be part of what binds our species together and allows a lot of interdependence. Cognitive psychology is a fascinating subject and I have read many good books that explore the irrational response in human beings. The best sceptics, those who usually have a professional understanding of psychology, tend to be a lot more forgiving about those who believe. This seems to come from a strong sense of self-awareness. As logical and rational as we like to think of ourselves, we hard-wired to think irrationally.
