Confirmation Bias
The tendency to look for, notice, and remember information that fits what a person already believes, and to overlook information that does not.
- Ex: A fan who believes a referee is biased against her team counts every call that goes against them and forgets the calls that go their way.
- Ex: A manager who has decided a new hire is careless notices each typo in his emails and does not notice the reports he turns in early.
- Ex: A person who reads a horoscope remembers the one line that matched her week and forgets the four lines that did not.
