自己評価:自己強化と自己検証

Self-enhancement is a desire to maintain, increase, or protect one's positive self-views, especially when facing threats to self-esteem. People employ strategies like affirmations—declarations that uphold valued aspects of oneself—to counteract negative feedback. For example, someone criticized for their personality might affirm their writing accomplishments in an unrelated domain to preserve self-worth.

The better-than-average effect describes how most people, particularly Westerners, believe they are above average across various personality traits and abilities. When evaluating themselves, people recall extreme positive examples of their behavior while judging others based on average or negative instances, creating an inflated self-image that supports self-enhancement motivations.

Self-verification theory proposes that individuals strive for stable, subjectively accurate beliefs about themselves to maintain coherence and predictability. Unlike self-enhancement, which seeks to improve self-image, self-verification motivates people to seek confirmation of their existing self-views, whether positive or negative, through interactions with others.

People display identity cues—outward expressions like clothing, accessories, and social choices—that align with their self-perceptions. Someone with a negative self-view might wear dark clothes, collect melancholy items, or associate with unenthusiastic partners. These cues signal their internal identity to others and increase the likelihood that social interactions confirm their existing self-beliefs.

Self-affirmation theory suggests that people can maintain self-worth by affirming themselves in domains unrelated to the threat they face. When experiencing criticism in one area, affirming accomplishments in another domain preserves overall self-esteem. This strategy allows individuals to protect their positive self-views without directly confronting the source of threat.

People balance both motivations depending on circumstances and emotional context. In emotional situations, individuals may prioritize being seen as slightly better versions of themselves through self-enhancement. However, they also seek stable self-verification to maintain coherence. The sense of self reflected self appraisal and social comparison helps explain how these competing motivations shape behavior and self-presentation choices.

According to self-verification theory, individuals seek confirmation of their existing self-views regardless of valence. Someone with a negative self-view may spend more time thinking about criticism and prefer interacting with others who ruminate similarly because these interactions validate their self-perception. This preference provides psychological consistency and predictability, even if the self-view is unfavorable.
