Refraction of the Day #23 Appeal To Ignorance

Appeal to Ignorance (Argumentum Ad Ignoratum): Asserting that something is the case because we don’t know that it is not the case. Refutation:  Lack of knowledge does NOT prove anything. It just demonstrates a need for new information. Example:   Betty, I don’t know of anyone who has died from marijuana use, therefore it is not fatal. Sidenote: While there are no confirmed cases of marijuana overdose death, there are cases involving marijuana use in which the used resulted in deaths.
