title: Psycho-logic: a 'conceptual toolbox' and 'mind sharpener' for health psychologists: a response to commentaries.
abstract: This is a reply to K. Glanz, J. Maddock, J. O. Prochaska, D. Seedhouse, and H. Stam on the target article entitled: 'A pragmatic basis for judging models and theories in health psychology: the axiomatic method'. I defend the claim that one should only test hypotheses that are empirical and avoid testing hypotheses that are necessarily true because of conceptual relations and logic. I argue that the axiomatic system Psycho-Logic (PL) should be added to the other methods which form the health psychologist's methodological 'toolbox'.
