TALK: Understanding and reducing the spread of misinformation online
There has been a great deal of concern about the negative impacts of online misinformation on democracy and society. In this talk, I provide an overview of my research on understanding why people share misinformation and how to combat spread of low-quality content online. I first focus on the why question and describe a hybrid lab-field study in which Twitter users (N=1,901) complete a cognitive survey. I show that people who rely on intuitive gut responses over analytical thinking share lower quality content. I then build on this observation with a Twitter field experiment (N= 5,379) that uses a subtle intervention to nudge people to think about accuracy. I show the intervention significantly improve the quality of the news sources they shared subsequently. Finally, I will talk about a follow-up study where we directly correct Twitter users (N=2000) who shared misinformation by replying to their false tweets by including a link to the fact-checking website. We show that unlike the subtle accuracy nudge, the direct public correction results in users sharing lower quality content. Our experimental design translates directly into an intervention that social media companies could deploy to fight misinformation online.
