Independent thinking, when overcome by Affinity Bias, is bad.
I’m not sure I get your point..
If you are saying that one can be an independent thinker and still be wrong - I agree.
On par, I still think independent thinking achieves far, far better results than trusting the “experts” - if for no other reason - because life is a competition, and people will pose as experts in order to take advantage of trusting souls.
