All of us have intuitively done something close to this thousands of times. You’ll start a criticism of a friend by saying, “I don’t want this to sound harsh . . .” hoping that whatever comes next will be softened. Or you’ll say, “I don’t want to seem like an asshole . . .” hoping your counterpart will tell you a few sentences later that you’re not that bad. The small but critical mistake this commits is denying the negative. That actually gives it credence.
