Optimism Bias - iluzia ca totul va fi bine


TedEd: Are we born to be optimistic, rather than realistic? Tali Sharot shares new research that suggests our brains are wired to look on the bright side -- and how that can be both dangerous and beneficial.




Wiki:

The optimism bias (also known as unrealistic or comparative optimism) is a bias that causes a person to believe that they are less at risk of experiencing a negative event compared to others. There are four factors that cause a person to be optimistically biased: their desired end state, their cognitive mechanisms, the information they have about themselves versus others, and overall mood.[1] The optimistic bias is seen in a number of situations. For example: people believing that they are less at risk of being a crime victim,[2] smokers believing that they are less likely to contract lung cancer or disease than other smokers, first-time bungee jumpers believing that they are less at risk of an injury than other jumpers,[3] or traders who think they are less exposed to losses in the markets.[4]
