Hello readers, my name is Ben and I’m a new member of the Blue-Genes team. I’ve been friends with Nico and Colin during our time at university, but was busy moving during the time the blog was founded. Now I’m here as a contributor, and will be posting again soon!
For scientists working in the field of HIV and AIDS, discussion of denialists can be at best tiring and at worst infuriating. This isn’t because a (‘good’) scientist can’t engage in a meaningful debate about their field with an honest dissident. It is because denialists of established science are not truly interested in objective examination of evidence. This may sound harsh, but it is important to realise that we’re not talking about any issues which have real controversy. The issue that I’m particularly talking about, the fact that HIV is the causative agent of AIDS, has over 25 years of medical science behind it, and is the subject of tens of thousands (1) of peer-reviewed research papers. The evidence is as irrefutable as that demonstrating that the earth orbits the sun, albeit perhaps less accessible to your average layperson.
Many may also dismiss denialist ramblings as the views of paranoid conspiracy theorists that have negligible influence on public perceptions. Unfortunately, undue attention has been given to the HIV and AIDS denialist movement due to the influence of particularly vocal leaders. The man generally regarded as the pole star of HIV denialism is the academic Peter Duesberg, who holds a Professorship with the department of Molecular and Cell biology at the University of California, Berkley. He is known for having performed work on the study of oncogenes, and was elected to the American National Academy of Science. Many people falsely see it as evidence for denialism that this impressive man holds views which would seem anathema compared to how one would expect a highly trained scientific mind to operate. One could indeed rhapsodise as to the reasons for this, but these reasons make not a jot of difference to the fact that his claims that the cause of AIDS is still controversial, and that the ‘Duesberg Hypothesis’ (claims that illegal drug abuse and antiretroviral medications themselves are the causes of AIDS) are demonstrably untrue (2).
HIV and AIDS denialism has had a painful influence on the governmental policies of South Africa. The previous Prime Minister Thabo Mbeki invited Duesberg and other denialists to sit on a 44-member ‘Presidential Advisory Panel’ to address the reliability of HIV test kits. The health minister at the time, Manto Tshabalala-Msimang rejected the use of antiretrovirals favouring an infamous approach based on eating beetroot, lemon, garlic and African sweet potatoes to save lives. It is concluded that hundreds of thousands of deaths (3) could have been avoided if a more rational approach to the issue could have been executed. The shady involvements of vitamin salespeople offering alternative respite has also tragically resulted in further confusion and death, with support from the government at the time.
An important concept to understand when considering a scientific issue is that of trust. Trust, slightly non-intuitively for some, is completely essential when engaging in scientific research or understanding issues said to be demonstrated by science. The scientific method (that is how scientists go about making new discoveries and ensuring they are well controlled, objectively conducted and concluded, and repeatable) is iterative in that it builds upon previously done work. Even to disagree with the interpretation of an experimental result or a potential theory necessitates allocation of trust, due to a previous benchmark of understanding of the field being required from which the dissidence can nucleate (4). The only way in which trust could hypothetically be avoided is to work from first principles – impossible in science unless you have an infinitely funded lab and the useful property of immortality and the patience to repeat well over a century of iterative experimentation.
It may be difficult to accept that trust in science isn’t particularly risky. Public suspicion rises with every less-than-satisfactory experience with one’s doctor or hospital, and most people in the know will confess that peer review is “flawed but the best we’ve got”. This highlights the importance of dissidence in relation to the system. It is important for people to question ideas which do not make sense to them, and to be able to have access to work done that has lead to the scientific community accepting the truth of particular issues. The earth is round. Vitamin C is required to prevent the onset of scurvy. HIV is the causative agent of AIDS. The difference between ‘dissidence’ and ‘denialism’ is that denialists maintain their stance (be it in regard to HIV and AIDS or any of many issues including the holocaust, or 9/11 as further highly emotionally charged examples) in the face of exhaustive and irrefutable evidence. It is not melodramatic to say that vocalisation of these particular falsehoods have been responsible for many deaths.

you are the murderer son…. you have no idea about the nature of the establishment whose ass your nose is buried in for your own egocentricism. The ’scientific consensus’ on this and many other issues had been severely tainted by the societal pressures on the scientisits themselves- which – while we are at it should be qualified and seen first for what they are….mere human beings, capable of collusion, scare tactics, vanity, covering their own mistakes when they feel justified and in the face of severe consequences, herd mentality, superstition, et al
What exactly is this vaccine combating ? since you people generally cannot establish viremia, meet cox postulates, your retro-virus is the only one to become infectious in the face of antibody immunity, you cannot produce good pictures of it just tricked up cellular garbage at the proper gradient, your test for this ‘killer’ differs significantly from country to country and doesn’t account for factors that have been shown to easily influence it, I could go ON AND ON AND ON…..Go be a toadie working for the death star if you want….this vaccine is smoke and mirrors just like the studies conducted to get aids CAUSING drugs like azt shoved up the public arse to the death and detriment of millions while you who are supposed to be ’scientists’ take no risks, take no meaningful positions, do no real research except that of a christian fundamentalist who already knows the earth was created in 7 days…now he’s just fitting the pieces into place that OBVIOUSLY prove it…. I cry for your
gullibility….. it’s just pitiful

If you’re still on the fence: grab your favorite earphones, head down to a Best Buy and ask to plug them into a Zune then an iPod and see which one sounds better to you, and which interface makes you smile more. Then you’ll know which is right for you.
