Compare market studies of decision making among consumers. One study indicates that both the "optimizer" and the "satisficer" tend to spend too much time making up their minds over choices that don't matter: Tierney, John. “The Price of Dithering.” New York Times 24 Mar 2008. <http://tierneylab.blogs.nytimes.com/2008/03/24/the-price-of-dithering/?pagemode=print>.
Compare neuroscience studies on How the brain makes decisions: "the trade-offs that have evolved in humans could not be more different from those that engineers made in designing conventional computers, however. Engineers chose accuracy. Brains, ... minimize energy consumption at all costs.... brains adapted to operate barely above the noise threshold.... the brain manages noise by using large numbers of neurons whenever it can.. It makes important decisions (such as "is that a lion or a tabby cat?") by having sizable goups fo neurons compete with each other -- a shouting match between the lion neurons and the tabby cat neurons in which the accidental silence (or spontaneous outburst) of a few nerve cells is overwhelmed by thousands of others. The winners silence the losers...." p. 61 Fox, Douglas. “Thinking machine: the future of computing may depend on embracing the chaos that defines the human brain.” Discover Oct 2009: 59-64, 75. <http://discovermagazine.com/2009/oct>.
