I have taught courses in critical thinking under the guise of “logic” as well as under the guise of “introduction to philosophy.” One of the best textbooks on critical thinking was (and perhaps still is) Critical Thinking: Evaluating Claims and Arguments in Everyday Life, by Brooke Noel Moore and Richard Parker. I have the 2d edition. Searching the Internet, I found that there currently is an 12th edition [cost, about $190]. But more interesting is that someone in China has placed the 9th edition on the Internet as a pdf file. So, before the copy disappears for some reason or other, download it while you can.
In this post, I am recommending that you read Chapter 4: Credibility and Chapter 5: Persuasion Through Rhetoric. These two chapters could be called “Bullshitting (especially in the News and Advertising Media) by language, pictures, and movies.”
