This is the worst part. Being fully aware that people are biased and that you are not a special exception to that isn't helpful. You're still just as likely to let bias influence your actions, and you'll probably try to justify yourself as having good reasons for your biased actions.
“A system cannot understand itself without help from outside the system, because prior experiences will bias objectivity, preventing critical analysis of the organization.” — Edward Deming
So, yes and no. That's why self awareness, perhaps via proper meditation, although I thought it was some hippy shit at first, is actually valuable.
I really don't think everybody is equally biased. Some people at least try to use reason and science to guide their beliefs, why other will systematically deny all evidences. Also people who are aware of biases are more likely to recognize their errors when called out with logical arguments.
Sure, but they also do so for specific reasons, like that considering evidence failed them in the past in some significant way. Possibly they just didn't do it right, but it's just incorrect to think people are the way they are for no logical reason.
(I think that’s what you meant?)
Maybe some people are better at avoiding bias than others, but from my experience people will be better in some areas while still prone to it in other areas.
