In his book THINKING, FAST AND SLOW Daniel Kahneman describes two schools of psychology within the study of decision making. Clinical psychologists advocate the use of methods like heuristics (rules of thumb) and intuition for making decisions.
Statistical psychologists, on the other hand, advocate the use of methods like simple algorithms or formulas for making decisions. Clinical psychologists believe their methods are better than the methods used by statistical psychologists and vice versa. The passion that each school of psychology has for its methods led me to examine my work as an FP&A practitioner.
