But the fact is that negotiating power is part and parcel of all human relationships. We recognize it most easily when it’s expressed outright, through authority, coercion, bullying, aggression, and castigation. The powerful one metes out punishments and rewards depending on one’s degree of compliance with his or her wishes. But there is also the power of the weak. Deference, passivity, withholding, ingratiation, and the moral one-upmanship of the victim are their own manifestations of might. Power and power imbalances are inescapable.
