A short warning that an argument may contain a logical fallacy helps people evaluate information more critically.
This is shown by research by Tilburg University and Université Paris Cité among 4,000 participants, published in Nature Climate Change. The study examined what influences people when evaluating arguments about climate change. Participants were shown different arguments; some were logically constructed, while others contained an error in reasoning.
The researchers found that people were mainly influenced by what they already believed about climate change. Lead researcher and social psychologist Bence Bagó (Tilburg University) said, "An argument that aligns with what someone already thinks was more often seen as strong. Yet people also looked at the quality of the argument.
This was especially the case when we gave people a small nudge to pay better attention to this." Participants were shown a short warning before some of the arguments: "Warning: this argument may contain a logical fallacy." They could then receive more information about possible logical fallacies. This small cue helped people better distinguish between strong and weak lines of reasoning. This was the case regardless of their political preference or what they already thought about climate change.
The researchers also tested the warnings on topics such as genetically modified crops, nanotechnology and artificial intelligence. There, too, the warning helped people evaluate arguments better. "People do not only look at what is being said, but also at whether it fits with what they already think.
A simple warning can help people pause for a moment and consider whether an argument actually makes sense. This could, for example, be useful on social media, where people encounter many different opinions and pieces of information about climate change," Bagó said. The researchers also looked at what happens when arguments are part of a political discussion.
