Theory has a clear dichotomy of meaning. 1. 95% of English speakers: I have a theory. Translation -- I just pulled this out of thin air or my posterior. I was just in a thread where a poster did this, and I get it. 2. 5% of English speakers: Theory of Evolution. Translation -- An extensively tested, refined, and widely accepted scientific hypothesis. ...Too bad it is not the LAW of Evolution. I avoid the word theory when posting in the science forums. Does anyone have a word that causes them issues when not dealing with nerds?
