Strangely enough, humans have an automatic negative brain response to other races. In a way, your attitude towards people is embedded in your subconscious.

How did we find out that the brain is racist?

Step 1. Participants were shown photos of faces for 100 ms (so fast that they didn't even realize they saw something).

Step 2. Then they were asked to guess the race of the person in the photo, and more than 50% of people were correct.

Interestingly, the higher the activity in the amygdala (which is activated in the brain's decision-making process about skin color), the higher the tendency towards racism in the participant, according to preliminary testing.

Does the brain not like strangers?

The bad news is, no, it doesn't like strangers. If you try to develop a reflex for fear when you see a portrait of yourself and a stranger, the reaction is developed faster to the image of "stranger". You could say we are a little biased, subconsciously attributing bad things to strangers and good things to ourselves. Even neutral faces of strangers are evaluated as more negative than the faces of members of our own group.

The good news is that if the face on the screen is shown to the participants for long enough for conscious perception, the frontal cortex is activated, which inhibits the ancient reflexes of the amygdala and cerebellum.

Therefore, you are still free to not be a racist, despite the brain's reactions. There is no need to condemn it, it evolved as best it could :)

If you believe that a person can control their worldview despite biology, share this with your friends or discuss it under this post :)
