Loud noises no problem. Heights 😵💫
Humans are born with just two innate fears: loud noises and falling. These hardwired responses help us survive in early life. The fear of falling was famously shown in the 1960 “visual cliff” experiment, where babies hesitated to crawl over a glass surface that looked like a drop. The fear of loud sounds shows up even earlier, triggering the startle reflex in newborns.
All other fears—like spiders, darkness, or public speaking—are learned through experience, culture, and observation. The “Little Albert” experiment showed how easily fear can be conditioned when a harmless object is paired with something frightening. Over time, our environment and upbringing shape the fears we carry.
