Duncan J. Watts, a New York Times columnist, wrote an essay about the choices we make and why we make them. This essay have an especial interest for all of us who share our work, photographs or other kind of art, on the web in places like flickr, weblogs or personal sites.
The common-sense view, however, makes a big assumption: that when people make decisions about what they like, they do so independently of one another. But people almost never make decisions independently — in part because the world abounds with so many choices that we have little hope of ever finding what we want on our own; in part because we are never really sure what we want anyway; and in part because what we often want is not so much to experience the “best” of everything as it is to experience the same things as other people and thereby also experience the benefits of sharing.
There’s nothing wrong with these tendencies. Ultimately, we’re all social beings, and without one another to rely on, life would be not only intolerable but meaningless. Yet our mutual dependence has unexpected consequences, one of which is that if people do not make decisions independently — if even in part they like things because other people like them — then predicting hits is not only difficult but actually impossible, no matter how much you know about individual tastes.
It is a good article, worth reading and can be found on the Nytimes. Read it and give it some thought.
