Here’s a special preview of the Cautionary Tales podcast from Pushkin Industries. On Cautionary Tales, bestselling author Tim Harford shares stories of human error, natural disasters, and tragic catastrophes from history that contain valuable lessons for today. In this preview, you’ll hear about two young girls who faked an image of fairies so compelling that expert photographers could not explain it and esteemed figures like Sir Arthur Conan Doyle were left believing in the existence of tiny nymphs.
