The Truth Bias vs. Misinformation: Exposure, Effects and Interventions
Jeff Hancock
Co-sponsored by the Goldman School of Public Policy
What can we learn about misinformation from decades of research on the psychology of deception detection?
In this talk I’ll lay out the state of the art in deception research and then apply some of these findings to what we know about misinformation and how it operates. I’ll describe new studies that map out the exposure of Americans to misinformation in the 2020 Presidential election and how particular groups of people were targeted and how misinformation had an effect on false beliefs about the election, all in line with predictions from deception research. I’ll also raise a core concern I have that all of our public discourse around misinformation may be undermining our default truth bias in credible news, and I propose several solutions for overcoming this “boy who cried wolf” problem, including digital media literacy interventions targeted at those that need them most.
