Common Mistakes uses the four synonyms of the word mistake (fallacy, error, accident, and blunder) to present a sample of widely held "truths" that have later proven to be misconceptions. The mistakes are illustrated with documentary before and after photographs, diagrams, and video footage, and prefaced with a clip from a childrens educational film on how to prevent accidents. Intercut between each mistake a silhouetted figure gives a brief monologue on the manner in which these broad social errors affected their individual lives. This contrast suggests both a compliancy and victimization of the individual in relation to issues such as racism, environmental pollution, and imperialism.
