Of course that is true but our discussions are mostly about religion or alternative medicine, or ghosts and angels and the like. I don't dismiss them outright but I am very scepticle about claims people make about these.
I believe science is based on beliefs. Not only can you do no science if you keep having to check if h, and e still have the same value, but much of science begins with the belief that a certain hypothesis might be the base of a good theory. On the other hand, if someone writes down an alternative to an established theory, many scientists will often dismiss it outright because of their strong beliefs in the existing theory.
