“Look to your left, look to your right: One of you won’t be here next year.” This intimidating line was immortalized as a greeting for incoming students at Harvard Law School in the classic movie, The Paper Chase. The explicit (and intended) message is that hard work is needed to be successful here. The implicit (and perhaps unintended) message is that your success occurs when others fail. In a competition, others must lose if you are to win, and so it’s natural to withhold information that might help others, or to fail to provide help when help may be needed. Clearly, this message inhibits teamwork. It’s hard to collaborate if you view (consciously or not) your colleague as the competition. Self-preservation is a powerful force.
