With so much information and misinformation available online, it can be hard to tell the difference. I just learned about a wonderful resource that can teach you how to do just that. It's a course called "Calling Bullshit" which was created in 2017 by a professor in the biology department and a professor in the information school at the University of Washington. Since teaching it in-person, they've made the syllabus, all the readings and case studies and tools, and even edited videos of all the lectures, available for free at this website: https://www.callingbullshit.org/index.html.
