For 99% of human history, the paranoid guy who couldn't sleep because he heard rustling outside the cave was the one who survived the night. The chill guy who couldn't be bothered got eaten by a leopard.
Natural selection rewarded hypervigilance, high cortisol, and an overdeveloped threat radar because in 10,000 BC, a false alarm cost you nothing but a missed nap while a missed threat cost you your life. So the genes that made it through are the ones wired to assume the worst.
You can see the same pattern everywhere. The people who could store fat efficiently survived the lean winters and famines, passed on their genes, and now those same genes in a world of cheap seed oils, endless processed carbs, and 24/7 food delivery make you pre-diabetic by 35. An adaptation that kept your ancestors alive for 200,000 years is now the leading cause of death in the modern world.
Or take intelligence for instance. For most of human history, being smarter meant better resource acquisition, better social status, more mates, more surviving offspring. But in the modern world, the correlation between IQ and fertility has completely flipped. Multiple studies across countries show a consistent negative relationship between cognitive ability and number of children. Higher IQ individuals delay reproduction, pursue more education, overthink the decision to have kids, and end up having fewer or none. The trait that was once the ultimate evolutionary advantage is now selecting itself out of the gene pool.
The takeaway here is that the stress response that kept your ancestors alive through ice ages and tribal warfare now fires because your Uber is 4 minutes late. Evolution built you to survive a world that no longer exists but nobody bothered to tell your amygdala.
Can a history nerd tell me what happens after a general population becomes so enraged and outraged against their ruling class that they start cheering for assassins? What comes next?
