I call it “Not Enough Tigers.” We humans have a dynamic response range of “sitting around the campfire with friends and eating great food” to “OMFG! TIGERS!” Unfortunately, most of our daily lives have compressed the dynamic range of experience into a gamut of watching Netflix to “someone said something I don’t like.”
Most people lack true existential threats in their day-to-day lives, and we humans come unglued without a proper dynamic range of experiences. I think this is why people who do dangerous things, such as urban bicyclists, rock climbers, SAR, and open ocean sailors, tend to be so laid back.
It also doesn’t help that those with power have had millennia to dial in propaganda to keep the hoi polloi divided against each other.
