the bias that we are better, smarter, and kinder than others
it makes your balls bigger!!
you have to reframe you it should be "what is the role of learning in perception?" Perception is heavily shaped by the self serving bias. The self serving bias is the fact that people will tend toward seeing that which best fits their internalized choice of belief. Such that unless a person is made aware of the self serving bias and works to counteract it, their perception of reality is more illusion then shared reality. Without focus on the reduction of the self serving bias in learning people tend to have perceptions of the information that will be bent to fit in their already self established bias reality of the understanding rather then form a new and clearer understanding untainted by their personalized bias of perception.
self-serving bias
I am a hard worker and that is why I was promoted. It has nothing to do with the fact that my father owns the business.
You can use a third party. Pick a group or a person that has not ties or interest in the results so that no bias gets into the mix.
Self-serving bias
This is known as the self-serving bias. It is a cognitive bias where individuals tend to attribute their successes to internal factors, such as their own abilities or efforts, while attributing failures to external factors, such as bad luck or situational factors. This bias helps protect self-esteem by maintaining a positive self-image.
