In a small study (n=80) undergraduate students were fitted with a wireless electroencephalography (EEG) headset. They were then asked to read political news headlines as they would appear on a Facebook feed to determine their credibility. They overwhelmingly chose headlines that aligned with their political beliefs as true.
“We all believe that we are better than the average person at detecting fake news, but that’s simply not possible,” said lead author Patricia Moravec, assistant professor of information, risk and operations management. “The environment of social media and our own biases make us all much worse than we think.”
