When Lack of Evidence Is Evidence of Lack



In their recent article “A Gentle Ethical Defence of Homeopathy,” Levy, Gadd, Kerridge, and Komesaroff use the claim that “lack of evidence is not equivalent to evidence of lack” as a component of their ethical defence of homeopathy. In response, this article argues that they cannot use this claim to shore up their ethical arguments. This is because it is false.
