It is suggested that the confidence bias can be explained by a noisy conversion of objective evidence (observation) into subjective estimates (judgment), whereas noise is defined as the mixing of memories during the storing (observing/learning) and retrieval process (remembering/judgment).  The information-theoretic logic behind this explanation is very similar to the mechanism that can also lead to the conservatism bias , and holds that we mix true and false evidence during storage and retrieval of evidence to and from our memories. The confidence bias results because as judges we "look inside our own memory" (evaluate our confidence) and find evidence that is more extreme than when we retrieve evidence for our judgements (which are conservative due to mixing of extreme values during retrieval). This explanation is very simple and straightforward, but nevertheless sufficient mechanism to generate both, overconfidence (in situations where judges are very sure) and underconfidence (in cases when judges openly state to lack the required knowledge).
My own theory, which I do not think of as complete or even adequate.
By stress, I don’t mean anything dramatic or exceptional. Commonplace activities qualify. Experiences such as being bored, arguing with a friend, falling in love, resisting temptation, flouting convention, learning a craft, breaking up with a partner, playing an instrument, giving a speech, reading Faulkner, memorizing a poem—these everyday analog endeavors are invaluable because they force us to confront discomfort. When we face these challenges, we might fail, fight back, become frustrated, succeed, lose our temper, calm down, feel confidence, overeat, undereat, go running, suffer insecurity, and so on. Through these experiences, in an honest attempt to face real challenges, we ultimately develop an anchored, adult identity capable of standing up to our digital demons.
High levels of mastery, low risk taking, and better health are ways to predict higher self-esteem. In terms of personality, emotionally stable, extroverted, and conscientious individuals experience higher self-esteem.  These predictors have shown us that self-esteem has trait-like qualities by remaining stable over time like personality and intelligence.  However, this does not mean it can not be changed.  Hispanic adolescents have a slightly lower self-esteem than their black and white peers, but then slightly higher levels by age 30.   African Americans have a sharper increase in self-esteem in adolescence and young adulthood compared to Whites. However, during old age, they experience a more rapid decline in self-esteem. 
What is important about the verses written by the painter in sentence 1?
They “were original and not conventional.”
