To agree with someone means to hold the same belief as them. But when you’re listening to someone (intellectuals, pundits, reviewers, etc.), how much of what they’re saying do you actually agree with, and how much are you intaking as new belief and not even thinking about whether you agree or not?
This can usually happen when you’ve determined in the past that you agree with a person on some things, and then you’ve made a mental leap towards seeing them as a general source of truth. But it’s a dangerous game. The fact that a person has some right beliefs about one thing doesn’t mean they will have quality beliefs about another.
It’s unwise to consider people as sources of truth. It’s best to 1) make yourself conscious of who you’re seeing as that and 2) get rid of that idea from your mind. Stop mindlessly consuming content from your perceived authoritative sources, assuming that you don’t need to be skeptical of what they’re saying. Don’t let your guard down. Question what you’re hearing.
