When Intentions Go Public Does

"When other people take notice of one's identity-relevant behavioral intentions, one's performance of the intended behaviors is compromised. This effect occurs both when the intentions are experimenter supplied and when they are self-generated, and is observed in both immediate performance and performance measured over a period of 1 week. It does not emerge when people are not committed to the superordinate identity goal. Other people's taking notice of one's identity-relevant intentions apparently engenders a premature sense of completeness regarding the identity goal."
