The very act of making decisions depletes our ability to make them well. So how do we navigate a world of endless choice?
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.
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. One shortcut is to become reckless: to act impulsively... The other shortcut is the ultimate energy saver: do nothing. Instead of agonizing over decisions, avoid any choice.
