A region of the brain linked with risk-taking has been identified by scientists, who say it could explain why some people are more likely to smoke and drink.
A team of neurologists from the University of Zurich found major functional and anatomical distinctions among those who are likely to smoke, use alcohol or drugs, speed, or have many sexual partners when compared to more cautious people.
For the study the Swiss team examined 25,000 people and found a direct relationship between differences in brain anatomy and propensity to take risks.
Distinct characteristics were found in regions of the brain responsible for controlling happy hormones like dopamine, memory storage and in managing self-control.
When genetic data meets marketing
Researchers from The Wharton School of the University of Pennsylvania published a new paper in the Journal of Marketing that assesses the implications of the growth of private genetic testing for the field of marketing and evaluates ethical challenges that arise. The researchers review past research in the field of behavioral genetics and use these findings to incorporate genetic influences into existing consumer behavior theory. They then survey potential uses of genetic data for marketing strategy and research, and raise concerns regarding significant ethical challenges that arise from unique features of genetic data.
The study, forthcoming in the Journal of Marketing, is titled Genetic Data: Potential Uses and Misuses in Marketing and is authored by Remi Daviet, Gideon Nave, and Jerry Wind.
