Politics aside, empathy is not about being nice or agreeing with the other side. It’s about understanding them. Empathy helps us learn the position the enemy is in, why their actions make sense (to them), and what might move them. As negotiators we use empathy because it works. Empathy is why the three fugitives came out after six hours of my late-night DJ voice. It’s what helped me succeed at what Sun Tzu called “the supreme art of war”: to subdue the enemy without fighting.
