The science of stepping outside comfort zones. In 1908, psychologists Robert Yerkes and John Dodson published a study on mice and electrical stimulation that revealed a counterintuitive pattern: moderate stress improved performance, but too little or too much impaired it. The resulting inverted U-shaped curve became one of psychology's most cited models for understanding why some degree of discomfort actually sharpens focus and decision-making.The next major shift came in 1979, when Daniel Kahneman and Amos Tversky published "Prospect Theory: An Analysis of Decision under Risk" in. Econometrica. Their research demonstrated that humans are not rational calculators of expected value. Instead, people feel the sting of a loss roughlytwice as intenselyas the pleasure of an equivalent gain, a bias they called loss aversion. Kahneman received the Nobel Prize in Economics in 2002 for this work
