Decision Fatigue

Interesting article I read (NYTimes: Do You Suffer From Decision Fatigue) about how the more decisions we make throughout the day the less logical and more emotional those decisions become. Also the more we resist temptation the more we deplete our willpower so perhaps going to a strip club after a day of shopping is not a good idea. What's interesting about this article is that, research shows that consuming sugar tends to restore our decision making and willpower but only temporarily. The author makes the point that because poor people have to make more decisions due to financial constraints, they make more poor decisions because of decision fatigue and low willpower but they also consume more unnecessary sugar as a result. I put together the following graphs to help me better understand this article, maybe you'll find them interesting:






Below are the main points of the article:
  • These experiments demonstrated that there is a finite store of mental energy for exerting self-control. When people fended off the temptation to scarf down M&M’s or freshly baked chocolate-chip cookies, they were then less able to resist other temptations.
  • The experiments confirmed the 19th-century notion of willpower being like a muscle that was fatigued with use, a force that could be conserved by avoiding temptation.
  • The word “decide” shares an etymological root with “homicide,” the Latin word “caedere,” meaning “to cut down” or “to kill,” and that loss looms especially large when decision fatigue sets in.
  • Once you’re mentally depleted, you become reluctant to make trade-offs, which involve a particularly advanced and taxing form of decision making.
  • Decision fatigue leaves you vulnerable to marketers who know how to time their sales.
  • Whether the customers paid a little extra for fancy wheel rims or a lot extra for a more powerful engine depended on when the choice was offered and how much willpower was left in the customer.
  • Similar results were found in the experiment with custom-made suits: once decision fatigue set in, people tended to settle for the recommended option. When they were confronted early on with the toughest decisions — the ones with the most options, like the 100 fabrics for the suit — they became fatigued more quickly and also reported enjoying the shopping experience less.
  • And this isn’t the only reason that sweet snacks are featured prominently at the cash register, just when shoppers are depleted after all their decisions in the aisles. With their willpower reduced, they’re more likely to yield to any kind of temptation, but they’re especially vulnerable to candy and soda and anything else offering a quick hit of sugar
  • The glucose would at least mitigate the ego depletion and sometimes completely reverse it. The restored willpower improved people’s self-control as well as the quality of their decisions: they resisted irrational bias when making choices, and when asked to make financial decisions, they were more likely to choose the better long-term strategy instead of going for a quick payoff.
  • Administering glucose completely reversed the brain changes wrought by depletion. Apparently ego depletion causes activity to rise in some parts of the brain and to decline in others. Your brain does not stop working when glucose is low. It stops doing some things and starts doing others. It responds more strongly to immediate rewards and pays less attention to long-term prospects.
  • The discoveries about glucose help explain why dieting is a uniquely difficult test of self-control — and why even people with phenomenally strong willpower in the rest of their lives can have such a hard time losing weight. : 1. In order not to eat, a dieter needs willpower. 2. In order to have willpower, a dieter needs to eat.
  • The mere expectation of having to exert self-control makes people hunger for sweets.
  • When faced with a new desire that produced some I-want-to-but-I-really-shouldn’t sort of inner conflict, they gave in more readily if they had already fended off earlier temptations, particularly if the new temptation came soon after a previously reported one.
  • His studies show that people with the best self-control are the ones who structure their lives so as to conserve willpower. They don’t schedule endless back-to-back meetings. They avoid temptations like all-you-can-eat buffets, and they establish habits that eliminate the mental effort of making choices. Instead of deciding every morning whether or not to force themselves to exercise, they set up regular appointments to work out with a friend. Instead of counting on willpower to remain robust all day, they conserve it so that it’s available for emergencies and important decisions.
  • “The best decision makers,” Baumeister says, “are the ones who know when not to trust themselves.”
