Two Kinds of People

It's called binary bias, a basic human tendency to seek clarity and closure by simplifying a complex continuum into two categories. 

When the amount of information is overwhelming and complex, our mind - with the mission of interpreting and making sense of those incoming data - tends to impose categorical distinctions and then makes decisions based on that.

Some examples:

• There are two types of men, married and divorced.
• There are two types of people, those who read and those who don't.
• There are two kinds of people, those who wear masks, and those who don't.

We sometimes take sides based on our binary bias and act on that. Beware!
