The Science of the Scream: Why We Love Being Scared
Every October, millions of people wait in long lines to walk through dark, labyrinthine haunted houses where masked actors leap from shadows. Others willingly strap themselves into roller coasters that drop hundreds of feet at highway speeds, or spend their evenings streaming terrifying movies with their hands clamped over their eyes. At first glance, this behavior seems completely irrational. Fear is an unpleasant emotion designed to alert us to danger and keep us alive. Why, then, would anyone intentionally seek out terror for entertainment?
The answer lies deep inside the human brain and our ancient evolutionary biology. When you encounter a sudden shockâsuch as a loud bang or a creepy figure jumping into viewâa small, almond-shaped cluster of neurons called the amygdala triggers an alarm. Before your conscious mind even has time to comprehend what happened, the amygdala sends an emergency signal to the hypothalamus, which activates the sympathetic nervous system. This instantaneous reaction is known as the fight-or-flight response.
