Many People Give Up Swimming in Lakes and Pools After Watching "Jaws."
Are three-quarters of us mentally ill wusses? Not according to the neurophysiology of fear. Joseph LeDoux [2] who studies fear reactions to real-life threatening events, identifies two distinct areas of the brain that are involved in the fear response: the prefrontal cortex, the area involved in conscious reasoning, and the amygdala, an almond-shaped lower-level area that's important for emotions. When you have an intense fright reaction, the amygdala responds fastest and creates the physiological response we refer to as fight-or-flight. Your cerebral cortex takes more time to react as it consciously evaluates whatever it was that frightened you.
Since the fear system is designed to help us survive life-threatening situations, LeDoux argues that it's important that our memories hold tightly to any intensely frightening experience. This way, we're prepared to protect ourselves if we're ever in that situation again. Research shows that although our conscious memories of traumatizing events are not always correct and are quite malleable over time, implicit fear memories that are stored in the amygdala are highly resistant to change. In fact, LeDoux says they're "indelible." [3]

The Amygdala Holds on Tight to Memories of Whatever Has Traumatized Us.
Keep in mind that our brains evolved a long time ago, long before reality was predominantly virtual. Back then, if you saw a vicious animal, a grotesque distortion of nature, or other people expressing fear, you were probably in mortal danger. [5] Today we see these things all the time on a variety of digital devices. And even though our higher-order reasoning tells us we're safe, our amygdala apparently isn't so sure.
So, no, Peejay, we may be irrational at times [6], but we're not nuts. Even as adults, our emotions can be strongly affected by what we watch, even if it's make-believe. And these emotions often linger.
The takeaway?—If you're feeling unnecessarily stressed out, keep your amygdala in mind as you choose your entertainment.
