Genetically
Modified Food Opponents Know Less than they Think, Research Finds

January 11, 2019 -- The people who hold the most extreme views opposing genetically modified (GM) foods think they know most about GM food science, but actually know the least, according to new research.
The paper, published Monday in Nature Human Behaviour, was a collaboration between researchers at the Leeds School of Business at CU Boulder, Washington University inSt. Louis , the
University of Toronto
and the University
of Pennsylvania
Marketing and psychology researchers asked more than 2,000U.S.
Despite a scientific consensus that GM foods are safe for human consumption and have the potential to provide significant benefits, many people oppose their use. More than 90 percent of study respondents reported some level of opposition to GM foods.
The paper’s key finding is that the more strongly people report being opposed to GM foods, the more knowledgeable they think they are on the topic, but the lower they score on an actual knowledge test.
Psychology of extremism
“This result is perverse, but is consistent with previous research on the psychology of extremism,” said Phil Fernbach, the study’s lead author and professor of marketing at the Leeds School of Business. “Extreme views often stem from people feeling they understand complex topics better than they do.”
A potential consequence of the phenomenon, according to the paper’s authors, is that the people who know the least about important scientific issues may be likely to stay that way, because they may not seek out—or be open to—new knowledge.
“Our findings suggest that changing peoples’ minds first requires them to appreciate what they don’t know,” said study co-author Nicholas Light, a Leeds School of Business PhD candidate. “Without this first step, educational interventions might not work very well to bring people in line with the scientific consensus.”
Beyond genetically modified foods
The paper’s authors also explored other issues, like gene therapy and climate change denial. They found the same results for gene therapy.
However, the pattern did not emerge for climate change denial. The researchers hypothesize that the climate change debate has become so politically polarized that people’s attitudes depend more on which group they affiliate with than how much they know about the issue.
Fernbach and Light plan to follow this paper with more research on how their findings play into other issues like vaccinations, nuclear power and homeopathic medicine.
