It is generally assumed that telling friends and family about your current goals is beneficial. A great deal of research has shown that when people explicitly state their intentions, they are more likely to follow through. This might be for a number of reasons including the need for self-consistency and the benefits of social support.
However, a recent investigation showed that publicizing your goals may actually lead to a lower likelihood of working toward them. In 4 studies, Peter Gollwitzer and colleagues (2009) asked people to report how important certain goals were to them. These responses were then turned into the experimenter who read them over (making them socially known) or set it aside without looking at them (making them private). Following this, the students completed tasks that were related to their goals. In all studies, they found that while both groups were made up of people strongly committed to their goals, it was people who kept their goals private that were more likely to actually engage in behaviors that were consistent with their intentions.
This finding, while somewhat surprising, is actually consistent with work done by classic theorists such as Kurt Lewin. Namely, the act of stating one’s intentions publicly is symbolic and creates a premature feeling of success, leading people to feel as if they’re already on their way to achieving their goals. In turn, this false sense of accomplishment makes people less likely to engage in the necessary behaviors for achieving those goals. And with this, I’m off to work on some of my own goals, none of which I can or should tell you about.
