Article speaking about the study
The study itself
Prejudice is the fact of having an opinion without a rationnal reason or without experience and in some case to act on that opinion. To do that, you need to be able to project yourself and stray from the path of rationnality following our cognitive biases (confirmation bias, survivor bias etc.).
Animals can't think deeply and therefore can't project beyond themselves and their ""opinions"" are always based on their experience or biology. Those are therefore rationnal reasons.
So no, they can't have prejudice.
Not really. When you really take a deep look at the experience, you understand that race is not a real factor (since the rats will act the same way with strangers from their own strains). It has more to do with experience in relationship to the social environement.
This study actually supports my argument of racism being a social construction.
