““Reason is flawed, but how badly? How should success or failure in reasoning be assessed? What are the mechanisms responsible? In spite of their often bitter disagreements, parties to these polemics have failed to question a basic dogma. All have taken for granted that the job of reasoning is to help individuals achieve greater knowledge and make better decisions. If you accept the dogma, then, yes, it is quite puzzling that reason should fall short of being impartial, objective, and logical. It is paradoxical that, quite commonly, reasoning should fail to bring people to agree and, even worse, that it should often exacerbate their differences. But why accept the dogma in the first place?””
