Genes may influence social media use, says study

A new study conducted by researchers from King`s College London has said that genes may strongly influence how people use social media sites such as Facebook, chat rooms and online gaming.
The researchers estimated the relative contribution of genes and environment on individual differences in engagement with a range of online media, including games for entertainment and education, as well as time spent on chat rooms, instant messaging platforms and Facebook. Heritability was substantial for time spent on all types of media including entertainment (37 per cent) and educational (34 per cent) media, online gaming (39 per cent) and social networking (24 per cent). Heritability describes the degree to which differences between children - in this case their use of online media - can be attributed to inherited genetic factors, rather than the effects of their environment.
Say the researchers, Unique environmental factors accounted for nearly two-thirds of the differences between people in online media use. These could include varying access to media sources within a family, such as one sibling having a personal mobile phone and the other not, or parents monitoring use of social networks more heavily for one sibling compared to the other. These findings challenge the belief that people are passively exposed to media and instead support a view that people tailor their online media use based on their own unique genetic predispositions. Our findings contradict popular media effects theories, which typically view the media as an external entity that has some effect - either good or bad - on `helpless` consumers. Finding that DNA differences substantially influence how individuals interact with the media puts the consumer in the driver`s seat, selecting and modifying their media exposure according to their needs. The key component of this gene-environment correlation is choice, such that individuals are not simply passive recipients of their environment but instead actively select their experiences and these selections are correlated with their genetic propensities.
