People in general, are not critical thinkers. We are herd animals who go along to get along. Thinking for yourself is not something most people actually do; however, everyone is sure they do it.
Knowing how to set aside an assumption and ask, “what if this is not true.” Knowing how to actually listen to another point of view with a mind that does not interrupt with your own opinion and prejudice. “Socratic Questioning” helps, if you know how to apply it to the self. Few do.
Listen closely, intently, and reserve an opinion with the willingness to be wrong. They want to convince us, because they have already made up their minds. They are right! It should be obvious to us.
