Learning to do this formally in a college philosophy/logic class broke my brain in the best way and drastically altered the kind of person I became from that point on. For context: I came from a religious family which had trained me not to trust my science teachers, but they hadn’t warned me against philosophers.

I think most people base most beliefs on being told that they're true. Full stop. It really comes down to who you are listening to and why; most critical to this is the birth lottery.

But do they know that?

I suspect most people believe themselves quite logical as to how they've arrived at their beliefs.
