Learn how to question and investigate claims about history. Study not only the logic of historical reasoning and argument, but also a lot of the practical tips and tricks real historians employ to test and check claims. Learn the particular skills of skeptical and critical thinking about history. Primary topics: Best practices among historians; historical methods as modes of reasoning (both criteria-based and Bayesian); examples of flawed reasoning and bad arguments in peer reviewed history journals and monographs (and how to spot them as a layperson); and what to do to critically examine a claim using both immediate heuristics and procedures for more labor-intensive inquiry.
