I am looking for a single word to describe something that is "believed to be true by the majority, but most likely not true". How could I say this?

If you can go with two words, common misconception is often used to describe that. Wikipedia even has a dedicated page for common misconceptions, which it defines as "erroneous beliefs that are currently widely held".
