The paint color in our master bathroom has been a source of debate since we bought our house. While I am certain that the color is firmly in the purple part of the spectrum, my husband insists that the paint is blue. Period.

Visiting friends have often been asked to weigh in on this debate, and the outcome is fascinatingly similar every time. When asking couples to cast their votes, men instantly declare the color to be blue. Women, on the other hand, typically pause before suggesting something like “periwinkle” or “lavender blue.”

This phenomenon has been played out between men and women time and time again—from selecting clothing to disagreeing at the paint store about whether one hue of blue looks more purple than another. Although you may be tempted to write off this difference as a consequence of cultural conditioning, the true root is physiological.

Humans are Wired for Prejudice, but That Doesn’t Have to be the End of the Story

Humans are highly social creatures. Our brains have evolved to allow us to survive and thrive in complex social environments. Accordingly, the behaviors and emotions that help us navigate our social sphere are entrenched in networks of neurons within our brains.

Social motivations, such as the desire to be a member of a group or to compete with others, are among the most basic human drives. In fact, our brains are able to assess “in-group” (us) and “out-group” (them) membership within a fraction of a second. This ability, once necessary for our survival, has largely become a detriment to society.

Understanding the neural network controlling these impulses, and those that temper them, may shed light on how to resolve social injustices that plague our world.
