Have you ever been wrong before?
All of us are wrong about countless beliefs we hold. We see/hear so many things that we can't judge the truth of and many of these remain in our minds consciously or under the surface.
Especially now with so such low quality info on the internet, we get suckered more than ever, especially into believing that which we find emotionally satisfying.
We also misremember ideas and event. Sometimes I've been near certain that X happened, only to find out later that this was a false memory.
Especially when it comes to your political or religious ideas, what have you been wrong about? How did you find out?
I used to think that I was highly rational, and that secular humanism was the 'common sense' result of getting rid of silly biases like religion, rather than being based on numerous culturally contingent axioms grounded in myth.
I found out by reading historical, philosophical and scientific texts and becoming more and being more sceptical of those who proclaimed their own rationality when I started to realise a lot of the standard anti-religious tropes are completely (or at least significantly) fictitious. I then thought of how I had accepted these as self-evident fact and would have defended them as "the truth" and seen any attempts to argue otherwise as "apologetics" and dismissed them out of hand.
Much of these illusions are maintained by a self-reinforcing thought bubble of like minded people, and because "we are all rational, sceptical evidence focused people" how could we all be so wrong?
Over time, the doubt started to creep in and I became more open minded.
Once the emotional block was removed, the science is pretty clear we have only limited capability to be rational, and the history/philosophy pretty clearly showed that my beliefs were indeed a culturally contingent ideology rather than "the common sense result of discarding myths".
Do you expect you're wrong about anything you believe now? Or will discover you're wrong again the future?
Of course. It's not uncommon for me to find out I'm wrong about something, I wouldn't be learning if that were not the case.
I change my mind quite a lot.
I also no doubt have ideological blind spots like I did when i was a Secular Humanist that inhibit attitude change. Some of these will come out in the wash sooner or later too.
