Study reveals the brain controls political beliefs


When it comes to President Donald Trump, do you ever defend your political beliefs even if there is evidence that contradicts them? One study suggests that might be because of a reaction in your brain.

During the whirlwind of the presidential election, you may have lost friends or even a significant other over a political disagreement.

A study at USC's Brain and Creativity Institute revealed that when someone's political beliefs are challenged, the emotional parts of their brain are activated.

The study revealed that because of those emotional reactions, the participants went into defense mode and were less likely to change their minds when they were challenged.
