Case Study: The ‘Iffy Quotient’

University of Michigan Center for Social Media Responsibility Uses NewsGuard Data in Its Iffy Quotient. The CSMR’s “Iffy Quotient” tool tracks the proportion of unreliable websites shared on Facebook and Twitter. The team uses NewsGuard’s ratings as a benchmark for distinguishing between reliable and unreliable sites. 

Case Study: Analyzing Content Recommendation Algorithms

Researchers at Dartmouth, Indiana, and South Florida use NewsGuard’s Index to develop improved content recommendation algorithms. A project led by Brendan Nyhan from Dartmouth College, Giovanni Luca Ciampaglia from the University of South Florida, and Filippo Menczer and Alessandro Flammini from Indiana University used the Index to study how to improve the diversity of information circulating on social media.
