Wolves and Doves - Lorenz (1952)
Some species (wolves) have weapons that make them hunters. They have instinctive inhibitions that prevent them from using their weapons on each other.
Non-hunting species (doves) don't have natural weapons, so they have not developed the same inhibitions - doves will just fly away from conflict.
Lorenz applied this to humans, he believed we are doves as we don't have natural weapons. Therefore we lack inhibition
Unfortunately, humans have developed weapons without developing instinctive inhibitions against using them
