Daniel Wolpert’s TED talk explores the exponential nature of tit for tat (or eye for an eye). We underestimate the force we generate when striking others. So when we think we retaliate in kind, the other experiences it as an escalation. They return with greater force and so it goes on. He’s talking about physical force but it applies to insults too, I reckon.
Which explains a heck of a lot about human conflict.
