Teaching people how to spot and outsmart a particularly tricky form of misinformation online is at the heart of new UW-Madison research recently funded by the National Science Foundation.
The research, led by educational psychology professor Martina Rau, will focus on visual misinformation — specifically, misinformation presented online in graphs. Rau has studied visual learning for more than a decade. She says visual misinformation in graphs can be particularly powerful because it can make false information seem more believable — and it reaches viewers very quickly.
“When you’re browsing the web, you encounter so many visual representations that aren’t good,” Rau said. “Every time we scroll through media, whether it’s social media or news media, we’re attracted to visuals. We’re more drawn to visual representations than text, and we don’t question those visuals as much.”
Martina RauRau said misleading graphs include three-dimensional pie charts that angle a certain section of the chart toward the viewer, in order to make that section seem bigger. A line graph with an axis that doesn’t start at zero is another culprit. Those graphs can cause viewers to accept falsehoods and make ill-informed decisions about things ranging from politics to medical care and product purchasing.
Rau’s project, which was funded for three years with roughly $850,000 from the National Science Foundation, will include the development of a tool that people can install on their web browsers. The tool will provide a short, two-minute training on how to spot misleading graphs — and point out those graphs as they show up during browsing. The goal is to “inoculate” people against misinformation in graphs, and then provide “boosters” as needed, Rau said.
