ABSTRACT
It is a popular notion that if psychology is to be considered a science, then it most certainly is not an exact science. The propositions of psychology are considered to be inexact because no psychologist on earth would venture a statement such as this: “All stable extraverts will, when asked, volunteer to participate in psychological experiments.” 1 The propositions of the natural sciences are considered to be exact because all physicists would be prepared to attest (with some few cautionary qualifications) that, “fire burns” or, more pretentiously, that “e = mc 2.” In short, it is felt that the order in the universe, which nearly everyone (though for different reasons) is sure must be there, has been more obviously demonstrated by the natural rather than the social scientists.
