By David Gordon, associate editor Disinformation efforts go back at least seven centuries, and social media and other new approaches to news dissemination may be increasing their effects, according to a UW-Eau Claire faculty member with more than two decades of experience in evaluating information. Kate Hinnant, head of instruction and communication at UW-EC’s McIntyre Library, spoke to some 20 people Tuesday evening to lead off a two-part series on “Information Self-Defense.” The programs are intended to help people distinguish between reliable information and “fake news,” in the context of both political campaigns and news media reporting. The series will conclude next Tuesday (Feb. 11) with another presentation by Hinnant at the L.E. Phillips Memorial Public Library. For more information, click on the headline.
