More importantly, it is difficult to study minds because we are mental beings. We have our own minds to maintain and protect, and may not wish to discover facts that force us to change, or make us question our own being in the world, or conflict with our sense of right and wrong. We have not discussed belief systems known as religions to any extent in this book. However, particularly threatening are facts that run counter to ourreligious beliefs, especially if those beliefs are strongly held. Further, scientists have hopes, standards, and ethical beliefs, and they—like anybody—are not eager to find that their beliefs are invalid.

Barry Schlenker’s self-identity theory (1982) asserts that self-presentation is an attempt to control information about your identity before real or imagined audiences—including yourself. People try to provide explanations of their own conduct; they try to construct an identity that is satisfying to themselves and that explains their behavior in a favorable light. One of the criteria of a good explanation is believability; that is, explanations must fit with existing knowledge. Schlenker argues that people are not motivated to attain cognitive consistency as an end in itself; rather, they need to provide a believable and self -beneficial account of their conduct, and consistency is a by-product of that. The need to provide explanations for your conduct results in the construction of an internally consistent view of reality.
