In recent years researchers have begun to build a science of interest, investigating what interest is, how interest develops, what makes things interesting, and how we can cultivate interest in ourselves and others. They are finding that interest can help us think more clearly, understand more deeply, and remember more accurately. Interest has the power to transform struggling performers, and to lift high achievers to a new plane.
So what is interest? Interest is a psychological state of engagement, experienced in the moment, and also a predisposition to engage repeatedly with particular ideas, events, or objects over time. Why do we have it? Paul Silvia of the University of North Carolina speculates that interest acts as an “approach urge” that pushes back against the “avoid urges” that would keep us in the realm of the safe and familiar. Interest pulls us toward the new, the edgy, the exotic. As Silvia puts it, interest “diversifies experience.” But interest also focuses experience. In a world too full of information, interests usefully narrow our choices: they lead us to pay attention to this and not to that
