Using the Tools of Quantitative Social Science to Study Fake News

11/14/2017

Using new data collection technologies, QSS steering committee members Brenda Nyhan and Yusaku Horiuchi, with Dartmouth undergraduate students from Nyhan’s “Experiments in Politics” course, have been able to contribute to social science research on the prevalence and effect of fake news and fact checking. A recent Dartmouth News story, “Dartmouth Scholar Is at the Center of the Fake News Debate” highlights Professor Nyhan and his work.

QSS students and faculty investigte the believability of fake news

10/24/2017

Three papers co-authored by QSS students and steering committee members investigate individuals' likelihood to be skeptical of false news. In thier paper "Media Source, Selective Exposure, and Susceptibility to False Information," Dartmouth students Katherine Clayton, Jase Davis, and Kristen Hinckley, with Professor Yusaku Horiuchi, investigate whether citizens' are more likely to believe false information based on the source of the news piece. In "Counting the Pinocchios: The Effect of Summary Fact-Checking Data on Perceived Accuracy and Favorability of Politicians," students Alexander Agadjanian, Nikita Bakhru, Victoria Chi, Devyn Greenberg, Byrne Hollander, Alexander Hurt, Joseph Kind, Ray Lu, Annie Ma, Daniel Pham, Michael Qian, Mackinley Tan, Clara Wang, Alexander  Wasdahl, and Alexandra Woodruff, with Professor Brendan Nyhan, study the effects of summary fact-checking (assessing the accuracy of politicians over time) on the favorability rating of those politicians. And in "Real Solutions for Fake News? Measuring the Effectiveness of General Warnings and Fact-Check Banners in Reducing Belief in False Stories on Social Media," Professor Nyhan worked with students Spencer Blair, Jonathan A. Busam, Katherine Clayton, Samuel Forstner, John Glance, Guy Green, Anna Kawata, Akhila Kovvuri, Jonathan Martin, Evan Morgan, Morgan Sandhu, Rachel Sang, Rachel Scholz-Bright, Austin T. Welch, Andrew G. Wolff, and Amanda Zhou explore the effectiveness of various strategies that could be used by social media platforms to counter fake news. Professors Nyan and Horiuchi also discussed these findings in an Upshot article, "Why the Fact-Checking at Facebook Needs to Be Checked" and a Monkey Cage article "Homegrown ‘fake news’ is a bigger problem than Russian propaganda. Here’s a way to make falsehoods more costly for politicians."

QSS Faculty publish findings on attitudes to refugees in Science Advances

09/06/2017

DJ Flynn, a postdoctoral fellow in the Program in Quantitative Social Science, and Yusaku Horiuchi, an affiliated faculty member in the program who teaches a popular data visualization course, have published a new article in Science Advances.  This article, which is co-authored with Jeremy Fewerda of the Department of Government, is an analysis of attitudes in the United States toward refugee resettlement. Ferwerda, Flynn, and Horiuchi show that Americans are less supportive of refugee resettlement locally than they are elsewhere in the United States.  This highlights how refugee resettlement is a collective action problem facing the country.  Ferwerda, Flynn, and Horiuchi also show that threatening media frames reduce support for refugee resettlement. In addition to the article in Science Advances, this research has also been covered in CITYLAB, (Even Liberals Can be Refugee NIMBYs) and in The Dartmouth News (Study Shows Support for Refugees Drops Off Closer to Home).
