Self-serving bias is when people see things in a way that makes them look good. This bias is shaped by who we are and the people around us. Research shows that about 80% of people show this bias, especially when their self-esteem is involved.

Personality Traits:

• People who feel good about themselves are more likely to show self-serving bias.
• Those who are narcissistic (very focused on themselves) tend to show this bias even more.

Social Influences:

• Different situations can increase this bias, like being in a competitive setting.
• When working in groups, people often believe that their successes come from their efforts (58% of the time). But when there are failures, they usually blame things outside of their control (72% of the time).

In summary, both our personal traits and the social situations we are in play a big part in how we show self-serving bias.
