Thanks to websites and social media platforms, conspiracy theories are able to reach a wider audience today than ever before. Such theories both fascinate and alarm critical thinkers because they challenge media consumers of all ages to hone their media literacy skills. This volume introduces the basic critical thinking concepts needed in order to evaluate the credibility of conspiracy theories, such as those surrounding the September 11 terrorist attacks and allegations of "crisis actors" after mass shootings, as well as the skills needed to debunk such theories. Case studies and examples walk the reader step-by-step through the methods readers can use to process and evaluate information related to conspiracy theories, helping to separate fact from fiction.
