unwillingness to re-evaluate
Original Dramatica Definition
Preconception is a pre-conception that prevents one from entertaining information contrary to a held conclusion. When one shuts his mind to additional data, there is no way to realize that the conclusion might be in error. Contradictory observation no longer becomes part of experience so experience ceases to grow. Obviously, this can lead to all kinds of actions and attitudes that work to the detriment of oneself and others. On the other hand, Preconception can steel one against temporary exceptions that tempt one to veer from the true path. Question -- Is it bad to have Preconceptions against evil?
