Has the Genetic Contribution to the Propensity to Gambling Increased?

Dr. Wendy Slutske examined data from national twin studies conducted in 1962 and 2002 to assess whether environmental changes, including the expansion of legalized gambling, had influenced the genetic and environmental factors contributing to individuals’ propensity to gamble. Despite significant changes in the gambling landscape over four decades, the study found no significant difference in the relative importance of genetic and environmental factors.
