typicality effect
You categorize objects based on how they 'should' work.
The 'typicality effect' shows that people process category members differently based on how well they fit a prototype.
In categorization tests, participants identify a 'robin' as a bird faster than they identify a 'penguin' as a bird. The brain doesn't just store category labels; it stores a mental average that makes unusual members harder to access.
Your brain prefers the common over the accurate.
