Please join the CJMD on Wednesday April 24 at 3:30 pm in CMU 126 for an in-person talk by Assistant Professor Yunkang Yang of Texas A&M. He will present the first large-scale study of image-based political misinformation on Facebook.

Abstract:
In the talk, I will present the first large-scale study of image-based political misinformation on Facebook. Our team collected 13,723,654 posts from 14,532 pages and 11,454 public groups from August through October 2020, posts that together account for nearly all engagement of U.S. public political content on Facebook. We used perceptual hashing to identify duplicate images and computer vision to identify political figures. We found that twenty-three percent of sampled political images (N = 1,000) contained misinformation, as did 20% of sampled images (N = 1,000) containing political figures. This finding challenges many previous studies that suggest the problem of misinformation is small or negligible. Our research shows that new computer-assisted methods can scale to millions of images, and help address perennial and long-unanswered calls for more systematic study of visual political communication.
