| Abstract: | A great deal of scholarly work has explored the motivations behind media consumption and other various communication traits. However, little research has investigated the sources of these motivations and virtually no research considers their potential genetic underpinnings. Drawing on the field of behavior genetics, we use a classical twin design study to examine the genetic and environmental influences on nine communication behaviors. Our findings indicate a substantial portion of the total variance in media habits can be attributed to genes, as much as one‐third of the variance in some instances. Mass communication scholars would benefit by paying closer attention to heritability when thinking about the causes as well as the consequences of media traits in contemporary society. |
