ABSTRACT

As pervasive as decision making under uncertainty is to human behavior, contemporary scholarship on the subject reflects a deeply rooted and long standing schism between two schools of thought on decision-making styles, whose presence was acknowledged as early as 1938 by Barnard when he wrote about the divergence between what he called

logical

and

nonlogical processes

that underlie decision making (Barnard, 1938, p. 36):

By

logical processes

I mean conscious thinking which could be expressed in words or other symbols, that is, reasoning. By

nonlogical

processes I mean those not capable of being expressed in words or as reasoning, which are only made known by a judgment, decision, or action [emphasis added].
