Boothroyd, Jucker et al. (2020).
Summary: This paper used three different approaches to provide convincing evidence that television is changing preferences. A cross-sectional study of 300 individuals in 7 villages showed that watching TV predicted a preference for thinner and curvier women. This was also true when looking at within-individual change in preferences from year to year amongst a small community who were tested multiple times. Finally, an experimental study showed that viewing high or low weight models on a laptop actively changed villagers’ preferences, as is also seen in the laboratory in the UK.
