The Biology of Human Interactions,a Strong Inference

Refresher

The nervous system allows us to perceive the environment while the brain integrates the incoming signals to determine an appropriate response.

Input to brain is filtered. What are you paying attention to?

Active seeking of infoversusSubconscious scanning for threats

Are humans better at detecting threats?

Coalition Membership

I like orange. Hook em’. I like to wear overalls.

Go Horns.I like to wear chaps.

I like Maroon.

Gig em’.

Go Aggies.

When alternate coalition membership information is introduced, race is ignored.

Despite a lifetime's experience of race as a predictor of social alliance, less than 4 min of exposure to an alternate social world was enough to deflate the tendency to categorize by race. These results suggest that racism may be a volatile and eradicable construct that persists only so long as it is actively maintained through being linked to parallel systems of social alliance.Can race be erased?
