The Role of Analytic Thinking in Resisting Misinformation and Propaganda on Social Media
A formal research report on why some people fall for misinformation and how to fight it. Drawing on studies in psychology and data science, it shows that the willingness to slow down and question first impressions protects people from false claims, then compares two kinds of solutions: education that builds critical thinking, and machine learning tools such as SMART 2.0 and propaganda-recognition models that track misinformation as it spreads.
It closes with recommendations, including keeping humans in the loop on AI moderation and measuring programs with data before scaling them up.
