are there other areas in my life where I'm also under influance of other false beliefs?
I think that is just part of life. Our life span is so limited that what we believe is the result of the knowledge available. People used to believe for thousands of years that the Sun revolved around the Earth. Millions died believing that. Then more information became available and we found out different.
I think we are all under undue influence in some way or another until we find out we are. Then we're not!
