Summary:
“Media reports about behavioural genetics unintentionally induce unfounded beliefs, therefore going against the educational purpose of scientific reporting,” writes a researcher following his study of 1,500 Americans. Public misunderstanding is not the only thing to blame for this misinterpretation. “Generally, science reporters’ first goal is to inform the public about scientific developments. However, this practice is not disinterested; some news is purposely written in a manner intended to catch the public’s attention with startling results in order to increase or to maintain market shares," the researcher explained.

“Media reports about behavioural genetics unintentionally induce unfounded beliefs, therefore going against the educational purpose of scientific reporting,” writes the University of Montreal’s Alexandre Morin-Chassé, following his study of 1,500 Americans. “Among other things, we wanted to know if the public understood (or misunderstood) popular science articles about a new research field, genopolitics, and whether this popularization indeed helped people have an informed opinion on human genetics,” Morin-Chassé explained.
The study participants first had to read a news article about research on the influence of a gene on one of the following three traits: breast cancer, political ideology (liberal or conservative), or the tendency to go into debt. After reading the article assigned to them, they were then asked to estimate the influence of genetics on various biological (e.g., hair colour, height) or behavioural (e.g., violence, alcoholism) traits on a scale from 0% genetic to 100% genetic. They were told that there were no right or wrong answers. The purpose of the study was simply to examine the interpretation of facts.
