"When all or most of a set of uncertain and imprecise pieces of evidence point in the same direction, we have the sort of situation where ignorance turns into hunch, hunch into belief, and, ultimately, belief into knowledge."

Arnold C. Harberger Some Evidence on the International Price Mechanism.  Journal of Political Economy, Vol. 65, No. 6 (Dec., 1957), pp. 506-521
