The Eternal Triangle Effect
"Communication, whether verbal or nonverbal, is often analyzed as the flow of information between sender and recipient. This causal model, drawn from classical physics, is all too often thought to be the whole story. But we have learned from quantum mechanics that, at least in physics, the entire past history of a system is needed to interpret the present, and that even with such knowledge we cannot guarantee the absence of novelty. In this paper we present a specific example of this general feature of quantum mechanics which has, we believe, a profound analogy to a well-known behavioral situation. We offer this analogy, not as a model, but rather in the hope that it will stimulate a different type of thinking about nonverbal communication and related phenomena."
