Self-serving Bias

We may not be fair or objective in some of our judgments.  This may be especially true with respect to judging ourselves.  We may be motivated to have a positive self-concept and high self-esteem.  As a result, we may be biased in how we perceived ourselves.

1.  Believing that you are more intelligent than you actually are.

2.  Believing that a positive outcome (e.g., writing a best-selling book) is completely due to your talents when it may be partly explained by chance factors or the efforts of others.

4.  Believing that you can become a famous singer when most people have doubted your singing ability.
