Professor Thomas's question suggests (to me at least) another one... 
 
What would be the usefulness (pros and cons) of having another 
organizing concept (besides theory, paradigm or research program) for a 
body of knowledge sharing some (which?) characteristics? 
 
Obviously, theory seems too narrow and paradigm too wide but... one more? 
 
Diversification makes sense only if correlations are substantially 
different from one.
