Do you ever wonder how much you're wrong about?

We all know life is a huge learning experience, but recently a Jelly asked to really think about something I believe in, which I have attempted to do.

It made me think, if I’m wrong about this, what else am I wrong about? Is there a right and wrong in life, or is it all experience and interpretation of individual reality?

If you’re wrong about some of your deeply held beliefs, whatever they are (politics, religion, etc…), could you wrap your mind around that (change) and truly examine the rest of your beliefs analytically in order to live a more authentic life?

If the answer is no, is there any point in self-examination and helping lead each other to the ‘truth’ (or arguing who’s right or who’s wrong) as we so often do on this site?
