Neuro Economics and Decision Making

James Heskett of Harvard Business School looks at neuro economics and decision making. An excerpt:

Among the propositions advanced from this work thus far, for example, are that risk and return are assessed in different parts of the brain, thereby questioning theories regarding expected utility on which a great deal of decision theory has been based up to now. Thus, according to this research, different qualities of, say, investment decisions are made when perceptions of risk or greed (return) prevail in terms of heightened brain activity. Another line of work involves the study of the best locus in the brain, conscious or subconscious, for making various decisions. For example, it is thought that more complex decisions involving hard-to-quantify factors are best made in the subconscious after some amount of preparation. That is, study the problem, sleep on it, and decide without further analysis. It's the type of decision making described by Malcolm Gladwell in his book, Blink. According to this line of thinking, questions involving more quantifiable, straightforward considerations are best answered in the conscious portion of the brain, presumably after considerable conscious thought. Work in neuro marketing at Ludwig-Maximilians University in Munich now claims that strong brands create more excitement in decision-influencing areas of the brain than weak brands, even for mundane products. Does this influence purchase decisions? Stay tuned.
