In Psychology, Self Enhancement is a common emotional bias. Also called self-enhancing bias. It is different from self improvement which is the act of bettering oneself.

We encounter the word bias, mostly for K-pop, to favor/lean towards to someone or something. In this case – to oneself. People engage in self-enhancement whenever they seek, interpret, or distort evidence about themselves in a way designed to maintain, create, or amplify a positive self-image.

Self-enhancement involves a preference over positive over negative self-views. It is said to be prominent in situations of threat, blows or failure to ones self-esteem.
“The only thing that sustains one through life is the consciousness of the immense inferiority of everybody else, and this is a feeling that I have always cultivated.”
Oscar Wilde
Based on Kwan et al. (2004), there are two concepts in Self enhancement. One conception originated from Festinger’s (1954) social-comparison theory and compares perceptions of the self with perceptions of others. *Social comparison and self insight.
- Self-enhancers are those individuals who perceive themselves more positively than they perceive others.
- Self-enhancers are individuals who perceive themselves more positively than they are perceived by others.

Research on Narcissism and Self Insight suggests that self enhancement is the fundamental characteristic of narcissism. In fact, narcissism has been called the “self-enhancer personality”.
Now we know the correlation of narcissism and self enhancement, with narcissism characterized by an overly inflated ego and self esteem. It is reported that scores on measures of narcissistic personality traits have been creeping steadily upward in recent decades in some cultures (Twenge, Konrath, Foster, Campbell, & Bushman, 2008). Twenge and Campbell (2009) argue that several interlocking factors are at work here, namely increasingly child-centered parenting styles, the cult of celebrity, the role of social media in promoting self-enhancement which sometimes hidden in the name of self-love.

A self-enhancer employs a variety of strategies to enhance their self worth. For example they can downplay skills they lack and criticize others that seem to be better in comparison. They sometimes self-enhance by remembering only their strengths and not their weaknesses. Also called selectivity or selective memory.
Then there’s selective acceptance, it involves taking as fact self-flattering or ego-enhancing information with little regard for its validity. Whatever strategy they use, having a self enhancer as your friend or companion is somehow toxic.
The ultimate driving force here – they are above everyone else, that they have more positive attributes and a more positive future outlook compared to others.
