Every so often, we come across an event where, as we watch the people involved, we conclude, "They have no idea what they're doing."
Sometimes we think that when we watch our favorite sports team get beaten badly by an opponent. Or perhaps as we watch a political candidate mishandle a question in a debate or an aggressive interview. Or maybe if we've ever had to sit through a performance in which one or more of the performers was clearly unprepared. We shake our heads, in bemusement, pity, or disgust, and we say to ourselves, "They have no idea what they're doing."
