  The next aspect of social nature of cognition is the phenomenon that members of a thought collective mutually reinforce themselves in the conviction that their thought style is true. Members of religious communities under group pressure do not consider their faith as one of many, but as the definite truth; they do not consider the principles of conduct which their faith imposes on them as the principles of one of many ways of living, but as those grasping of the essence of morality etc. Also scientists are convinced that their thought style is at least partially true today, and with time, when they work together, it will get closer and closer to being true. Yet, one may say, the conviction as to the truth of a thought style can break down under the pressure of facts that contradict it, and also as a result of confrontation with those who think differently. The remarks given above quite clearly show that this is not the case. Nonetheless let us summarize Fleck’s views on those matters.
