Genetic Variability and Collective Social Norms: The Case of Binge Drinking

This paper explores how collective social norms can have individual-level genetic foundation. Our study is the first we know to report a plausible link between genetically founded individual preferences in a fraction of a population and social norms governing behavior of all individuals.

As our motivating example, we focus on patterns of Excessive Drinking in Social Situations (EDSS) across Europe that are possibly triggered by genetically caused variations in personality. The genetic trait is shyness, which correlates with eye color.

We present empirical results indicating that alcohol consumption in social situations correlate with eye color and a model which suggests that conditions exist in which EDSS can emerge as a strategy in a larger fraction of the population than is genetically redisposed to EDSS.

In addition, our model shows that alcohol taxes may be counter-productive in controlling the emergence of EDSS as a social norm.
