People like to support their team. It’s called tribalism.It’s a way of thinking or behaving in which people are excessively loyal to their tribe, but in terms of human behavior.
And your tribe could be a lot of things. it could be the company you work for, your school family, local sports team, or your political party. When people see themselves as part of a tribe they will often go out of their way to defend the beliefs of their tribe regardless of whether or not they’re right or wrong. This could be due to our human desire for acceptance from within our group and something that social psychologists call naive realism.
Naive realism is the human tendency to believe that we see the world around us objectively and anyone who disagrees with us is either uninformed irrational or biased. This means that if we think that a person or even a media outlet is part of the other tribe, that we are far less likely to seriously consider anything that they have to say. It is something that we are all guilty of.
