Counterwill is an instinctive, automatic resistance to any sense of being forced. It is triggered whenever a person feels controlled or pressured to do someone else’s bidding. It makes its most dramatic appearance in the second year of life—yes, the so-called terrible two’s. (If two-year-olds could make up such labels, they would perhaps describe their parents as going through the “terrible thirties.”) Counterwill reappears with a vengeance during adolescence but it can be activated at any age—many adults experience it.
