June 3, 2015 - First impressions are important. So much so that even armed with new information, many people won’t change their minds about genetically modified foods and global warming, a new University of Florida study led by Brandon McFadden shows. Study participants were asked to assess the extent to which they believe human involvement caused global warming. They were given choices ranging from “much less involved” to “much more involved.” The study showed that before they received the information, 64 percent believed human actions are causing global warming; 18 percent were not sure and 18 percent did not believe human actions are to blame. After receiving scientific information about global warming, about 50 percent of participants believed even more strongly that human actions lead to global warming, while 44 percent were not swayed by the information, the study showed. "Possibly, the best indicator for whether a person will adopt scientific information is simply what a person believes before receiving the information," McFadden said.
