Optimism Bias

You overestimate the likelihood of positive outcomes.

There can be benefits to a positive attitude, but it’s unwise to allow such an attitude to adversely affect our ability to make rational judgments (they’re not mutually exclusive). Wishful thinking can be a tragic irony insofar as it can create more negative outcomes, such as in the case of problem gambling.

If you make rational, realistic judgments you’ll have a lot more tofeel positive about.
