Definition:

Optimism bias is the tendency to overestimate the likelihood of positive outcomes and underestimate the likelihood of negative outcomes. It is a form of self-deception that can lead to unrealistic expectations and poor decision-making.

Examples:

One example of optimism bias is when people overestimate their chances of success in a job interview. They may think they have a better chance of getting the job than they actually do. Another example is when people underestimate the risks of a new venture. They may think the venture will be more successful than it actually is.

Effects:

The effects of optimism bias can be both positive and negative. On the positive side, it can lead to increased motivation and improved performance. On the negative side, it can lead to unrealistic expectations and poor decision-making. It can also lead to a false sense of security, which can lead to risky behavior. In the long run, this can have serious consequences for individuals and society.

Overall, optimism bias can be a double-edged sword. It can lead to increased motivation and improved performance, but it can also lead to unrealistic expectations and poor decision-making. It is important to be aware of this bias and to take steps to mitigate its effects.
