What makes it so difficult for people to change their mind about something?

I get it — ego, pride, etc.— but why is it a default setting? Why is asking questions in an attempt to seek objective truth so taboo?

I guess we can blame the education system, but man, it’s crazy to see such a large cohort of people who think they are thinking for themselves, yet are unwilling to change their stance on anything.

I question my convictions probably too much, but in an effort to maintain truth. It’s not easy, but it’s necessary to continue to live in reality.
