Convention at a Glance: An Album of Research Vignettes
When false information is released, often a retraction or correction will be issue to fix the mistake. Even then, many people will still believe the false information, and despite an organization’s best efforts, the false information will continue to spread.
Psychological scientists have learned that interventions such as highlighting errors in the text do not prevent people from absorbing misinformation. The only strategy that works is asking people to closely scrutinize the text. Yet even while people are searching for errors, they need some prior information to reject the misinformation. Researchers demonstrated this effect by placing implausible or true facts in either a real-world story or a fantasy story. People picked up less false information from the fantasy story, but also picked up just as much correct information as they did from the real-world story.
Another question was whether attitudes would influence misinformation. In one Australian study, investigators presented volunteers with a story of a robbery committed by an Aboriginal. Volunteers who showed high prejudice toward Aboriginals were more likely to refer to the fact that the thief was Aboriginal than low-prejudice volunteers. But both groups were equally likely to accept retraction that the thief wasn’t Aboriginal. A similar result occurred when the story featured an Aboriginal as the hero.
Attitudes may not influence misinformation, but another line of research shows that self-affirmation can make people more likely to accept corrections and reduces misperceptions. Graphs are also more effective than text at reducing misperceptions among individuals who have strong beliefs about the existence of global warming.
Still, text has some power to correct misinformation. Many people have strong opinions about global warming. Changing people’s minds attitudes about global warming may seem daunting, but one study showed that all it takes is a 400-word blurb about the mechanism of global warming. After reading the blurb, people were more likely to agree that climate change was occurring.
Overall, none of the strategies employed by these psychological scientists were 100 percent effective at reducing misinformation, but these approaches could help reduce the spread of misinformation and help promote truth.
