"Ludwig von Mises who observed (contra Keynesianism) that you can't really apply "Hard Science" (Physics, Chemistry, etc.) equations to "Soft Science" (Sociology, Economics, etc.) questions -- because the Soft Sciences are based upon the actions of self-motivated, free-willed, independent actors -- not mathematically-quantifiable magnetic charges."
Actually, you can, but it has to be done along the lines of statistical thermodynamics - predicting the tendencies [like "entropy increases"], and not the individual outcomes. Here is a true story and illustration of this method:
My former workplace once conducted an executive search for a "sweep" [SVP- senior vice-president]. For about half a year the large office had stood empty, and nobody knew who, or when, would come to occupy it. Once, few months before they found their sweep, I had predicted to my co-workers the future nameplate for that office door. I assumed the exaggerated wild facial expression of a prophet from bad movies, and with defocused gaze and outstretched hands, prophesied as follows: "I see it... I see it... "GREEDY A-HOLE!"
Well, several months later they did find their sweep. And wouldn't you know - my prediction turned out to be so correct that a year later they had to squeeze him out - he was too much even for them!

Good point. I'd agree with that.

And good story. :-)
