Similarity Bias
A “similarity bias” results when individuals are more likely to imitate cultural models that are perceived as being similar to the individual, based on specific traits (such, for instance, age, gender, geographical location and so on…).
Similarity bias is even enhanced by our other bias, which we call snap judgement, whereby we unconsciously make up our mind on someone during the first milliseconds after we meet.
Similarity bias happens when we select people that are more similar to us, as opposed to people who appear more different. Evolution has fostered this trait, as a key manner to survive ever since the difficult times when we would live in the savannah, trying to escape from animals and all sorts of dangers.
