Why is the country so divided? Or why is the other side so evil?

The truth is that people have a strong natural tendency to believe what they want to believe. It is called “confirmation bias.” The brain naturally screens out a lot of input and selects feedback that confirms what we already believe. Then there is the fight or flight instinct. In other words, cavemen that made quick, imperfect decisions became our ancestors.

Hypothetically, confirmation bias could lead to electing a senile old man, a word salad addict or maybe even an off-the-charts egomaniac for president. You just never know.
