She quoted Barrett as saying that "a lot of things don't need to be tested [because] they simply don't make any sense". Writing in The Lancet, Mona Okasha wrote that Quackwatch provides an "entertaining read", but described it as only appropriate for limited use as it fails to provide a balanced view of alternative cancer treatments. Jane Cuzzell viewed Quackwatch similarly, arguing that it was entertaining but that the "resource value of this site depends on what the visitor is seeking" and had concerns about the appearance of bias in the selection of the material. However, while Lillian Brazin also found it to be biased, she described Quackwatch as credible, and noted both the credentials of the contributors and the thoroughness of the content. In a 2002 book, Ned Vankevitch, associate professor of communications at Trinity Western University, places Barrett in a historical tradition of anti-quackery, embracing such figures as Morris Fishbein and Abraham Flexner, which has been part of American medical culture since the early-twentieth century. Although acknowledging that Quackwatch's "exposé of dangerous and fraudulent health products represents an important social and ethical response to deception and exploitation", Vankevitch criticizes Barrett for attempting to limit "medical diversity", employing "denigrating terminology", categorizing all complementary and alternative medicine as a species of medical hucksterism, failing to condemn shortcomings within conventional biomedicine, and for promoting an exclusionary model of medical scientism and health that serves hegemonic interests and does not fully address patient needs. Waltraud Ernst, professor of the history of medicine at Oxford Brookes University, commenting on Vankevitch's observations in 2002, agrees that attempts to police the "medical cyber-market with a view to preventing fraudulent and potentially harmful practices may well be justified". She commends "Barrett's concern for unsubstantiated promotion and hype," and says that "Barrett's concern for fraudulent and potentially dangerous medical practices is important," but she sees Barrett's use of "an antiquarian term such as 'quack'" as part of a "dichotomising discourse that aims to discredit the "'old-fashioned', 'traditional', 'folksy' and heterodox by contrasting it with the 'modern', 'scientific' and orthodox."
