Self-affirmation

The theory of self-affirmation is a psychological theory that was first proposed by Claude Steele (1988) with the premise that people are motivated to maintain the integrity of the self. The ultimate goal of the self is to protect an image of its self-integrity, morality and adequacy. On the whole, integrity is defined as the sense that one is a good and appropriate person and the term "appropriate" refers to behavior that is fitting or suitable given the cultural norms and the salient demands on people within their culture. This theory explains why people respond in such a way to restore self-worth when their image of self-integrity is threatened. In this theory, people would respond to the threat using the indirect psychological adaptation of affirming alternative self resources unrelated to the provoking threat. As a result, these "self-affirmations" enable people to deal with threatening events and information without resorting to defensive biases, by fulfilling the need to protect self-integrity in the face of threat. In fact, this self-affirmation allows people to respond to the threatening information in a more open and even-handed manner.
