We have previously established that the HIV epidemic is being used as a lever by which to promote universal circumcision.[1] Men who promote male circumcision are driven by emotional factors related to circumcision. According to Goldman:
"One reason that flawed studies are published is that science is affected by cultural values. A principal method of preserving cultural values is to disguise them as truths that are based on scientific research. This 'research' can then be used to support questionable and harmful cultural values such as circumcision. This explains the claimed medical 'benefits' of circumcision."

"Defending circumcision requires minimizing or dismissing the harm and producing overstated medical claims about protection from future harm. The ongoing denial requires the acceptance of false beliefs and misunderstandings of facts. These psychological factors affect professionals, members of religious groups and parents involved in the practice. Cultural conformity is a major force perpetuating non-religious circumcision, and to a greater degree, religious circumcision. The avoidance of guilt and the reluctance to acknowledge the mistake and all that that implies help to explain the tenacity with which the practice is defended."[2]

There is a long history of circumcision advocates producing evidence to support their goal. For example, Abraham Wolbarst, who had written defending ritual circumcision,[3] later published "research" which "proved" that circumcision prevented penile cancer.[4] Unfortunately for Dr. Wolbarst, cases of cancer in circumcised men kept appearing[5,6] and the falseness of his claims were revealed to the world.

When we review the medical literature regarding the use of circumcision to prevent HIV infection, we frequently find that the author(s) previously have made statements or written articles in favor of circumcision to prevent various diseases, including AIDS. Consequently, we regard such "research" with deep suspicion, since we feel that such studies are undertaken to "prove" previously held beliefs. Researcher bias may be overwhelming and, under such circumstances, the studies can have only one outcome - that male circumcision has a strong protective effect against HIV infection. Such studies simply cannot be believed.

HIV infection is common among children in Africa.[7] These infections are not sexually transmitted, so any paradigm, which exclusively relies on the sexual transmission of HIV infection, is flawed.

The excellent and detailed statistical analysis by Williams et al.[8], therefore, is based on flawed science, so cannot be taken seriously.
