When technological advances paved the way for digital books, films and music, many commentators predicted the demise of their physical equivalents. It hasn’t happened, so far at least. For instance, while there is a huge market in e-books, print books remain dominant. A large part of the reason comes down to psychology – we value things that we own, or anticipate owning, in large part because we see them as an extension of ourselves. And, stated simply, it’s easier to develop meaningful feelings of ownership over a physical entity than a digital one. A new paper in the Journal of Consumer Research presents a series of studies that demonstrate this difference. “Our findings illustrate how psychological ownership engenders a difference in the perceived value of physical and digital goods, yielding new insights into the relationship between consumers and their possessions,” the researchers said.
