From John Tierney in NY Times: Deci­sion fatigue helps explain why ordi­narily sensible people get angry at colleagues and fami­lies, splurge on clothes, buy junk food at the super­market and can’t resist the dealer’s offer to rust­proof their new car. No matter how rational and high-minded you try to be, you can’t make deci­sion after deci­sion without paying a biolog­ical price. It’s different from ordi­nary phys­ical fatigue — you’re not consciously aware of being tired — but you’re low on mental energy. The more choices you make throughout the day, the harder each one becomes for your brain, and even­tu­ally it looks for short­cuts, usually in either of two very different ways. · Go to Do you suffer from deci­sion fatigue? →
