There is a clear reason why - there was, and is no consensus on electron flow. Thus the Electron theory - not the Electron Law, that is commonly used today. Years ago, there were two basic, and opposing schools of thought as it relates to current flow. The Electron theory supposes that current flows from positive to negative. There was another commonly used theory that stated the current flows from negative to postive - the Hall Theory. Eventually, a standard was adopted - that of the Electron Theory and making negative ground the standard. It is NOT proven. Conventional theory, also known as HOLE THEORY, states that current flows from POSITIVE to NEGATIVE. Protons or the lack of electrons (the holes) move towards the negative. (Current flow direction in Hole Theory is the opposite of that in Electron Theory.)
