The confusion of [in-group] vs. [out-group]

To understand many of our social reactions, it's helpful to look at our evolutionary heritage.

Biologically, we're hardwired to favor our "in-group" or "tribe."

For millennia, survival depended on group cohesion over rival tribes.

Our brains developed mechanisms to quickly identify who is "one of us" and who is not.

This bias, known as in-group bias, is based on the idea that those who share similarities with us (family, appearance, customs) are more likely to share our genes, and it's therefore beneficial to our own genetic survival to favor them.

We feel a natural affinity and greater trust toward members of our group, while we show suspicion and potential hostility toward the "others," those in the outgroup.

The Complexity of Modern Identities

In the animal world, identifying with the group is relatively simple.

However, in complex modern human society, this identification becomes incredibly confusing.

We are no longer defined by a single tribe.

We simultaneously belong to multiple "groups": our family, our city, our favorite sports team, our political party, our hobbies, our profession.

This creates a maze of identities that often conflict.

What happens when a close relative supports the rival football team? Our brains receive conflicting signals: "he's one of us" (family) and "he's one of the others" (rival).

This confusion is a constant feature of our social lives, and our brains, with their old wiring, struggle to process this overload of intersecting identities.

The Belonging Bias Manipulation

This innate confusion is fertile ground for manipulation.

Politicians, advertisers, and leaders of all stripes are adept at exploiting our belonging bias to gain our loyalty.

They do this by emphasizing a shared identity ("we are the w
