Are scientific experts always reliable?

Modern science has developed very powerful technologies that may cause irreversible and global damage. Genetic Engineering is one such technology.

It is most important that those who are trusted to judge the feasibility and safety of these technologies are uninvolved in them. That is, they must not have any kind of personal interest in them and must not be influenced by, or dependent on, the industry applying the technology.

Unfortunately, there are reasons to believe that this has not been the case in the evaluation of biotechnology. The judgement and recommendations by leading experts in this field indicates an obvious bias in favour of the application of gene technology. For example, the experts of FAO have demonstrated serious neglect of unfavourable observations indicating and a conspicious partiality in their judgement of the value and safety of genetic engineering of food as revealed in the article "Fatal Flaws in Food Safety Assessment: Critique of the Joint FAO/WHO Biotechnology and Food Safety Report".

The article below reports a study that found a significant biasing influence from the pharmacological industry on the conclusions of scientists. Obviously, there are reasons to believe that this is not an unique event. This problem is also discussed in the article "The Fallibility of Scientific Authorities". Therefore, for evaluation of new technologies we have suggested a procedure to secure an impartial assessment.

The conclusion of the article below is:

"In other words, if you want to understand "objectivity" in the science and medicine of environment-and-health these days, the same advice applies as it does in politics: follow the money. Increased corporate funding of science and medicine has the potential to corrupt almost anyone. "

FOLLOW THE MONEY (excerpt)

As government has been "downsized" in recent years, corporations have found opportunities to fund scientific research and education that the government used to fund. Will this give corporations the chance to influence scientific and medical opinions? Put another way, are scientific and medical experts able to take corporate money without subtly altering their scientific and medical views?

A recent article in the NEW ENGLAND JOURNAL OF MEDICINE1 (NEJM) --the first research of its kind --shows pretty clearly that scientific and medical experts who take corporate money hold opinions that differ significantly from experts who don't take corporate money.[1]

Researchers in Toronto, Canada examined a medical controversy to see which scientists held what sorts of views. The controversy they studied was the use of calcium-channel blockers, which are used to treat high blood pressure and heart disease. In 1995 the National Heart, Lung and Blood Institute warned doctors that one such channel-blocker increased the risk of heart attack deaths.[2] Other channel-blockers fell under suspicion of being dangerous.

The Toronto researchers examined 70 articles on channel-blockers, classified the authors into three categories (supporters, neutral, and critical), then mailed surveys to the authors, asking about their financial ties to drug corporations. The 70 articles had a total of 86 authors, and 71 of those returned the surveys. The surveys were intended to answer 3 questions:

1) Whether supporters of calcium-channel blockers were more likely than other authors to have financial ties to manufacturers of calcium-channel blockers. The answer was yes. Ninety-six percent of the supportive authors had financial relationships with manufacturers, as compared with 60 percent of the neutral authors, and 37 percent of the critical authors.

2) Were critics of calcium channel-blockers more likely than other authors to have financial ties to manufacturers of competing products (beta-blockers, angiotensin-converting-enzyme inhibitors, diuretics, and nitrates). The answer was no. In fact, supportive and neutral authors were more likely than critical authors to have financial ties to manufacturers of competing products (88% and 53% respectively, vs. 37%).

3) Were supporters of calcium-channel blockers more likely than other authors to have financial ties with ANY pharmaceutical manufacturers? The answer was yes. One hundred percent of the supportive authors, compared with 67% of the neutral authors, and 43% of the critical authors, had financial ties to at least one pharmaceutical manufacturer.

Financial ties are defined as any of these five: funds for travel expenses; honorariums for speeches; support for educational programs; research grants; and employment or consulting compensation.

The researchers noted that their study relied on self-reported data and therefore probably underestimated the actual ties between scientists and corporate funders.

The authors noted that in only 2 of the 70 articles did authors divulge their connections to corporations. They concluded, "The medical profession has failed to develop and enforce strict guidelines for disclosing conflicts of interest." And, "Full disclosure of relationships between physicians and pharmaceutical manufacturers is necessary to affirm the integrity of the medical profession and maintain public confidence.

(Here is a long piece of text about an incidient indicating that "unfortunately, even the columns of the most prestigious medical journal in the U.S. --THE NEW ENGLAND JOURNAL OF MEDICINE (NEJM) --have been infiltrated by corporate shills posing as objective medical experts." You will find the whole story at URL: gopher://ftp.std.com:70/11/periodicals/rachel , where you look up article #581)

The article finishes with these remarks:

"In any case Safe himself told BOSTON GLOBE reporter Larry Tye, "I felt a little twinge" about the potential for a conflict of interest when writing the editorial, "but it was not much of a twinge," he said. However, "I can see why people would bring it up," he said. Safe defended himself saying, "There's hardly any life scientist in the country who hasn't had funding from the industry" --the old "Everybody's doing it" defense.

Unfortunately, just about everybody IS doing it. In modern times, it pays to be alert when you are receiving opinions from "unbiased" scientific and medical investigators. As George Annas, professor of health law at the Boston University School of Public Health points out, "Almost all experts in the field at some point have taken grant money or an honorarium from someone."

In other words, if you want to understand "objectivity" in the science and medicine of environment-and-health these days, the same advice applies as it does in politics: follow the money. Increased corporate funding of science and medicine has the potential to corrupt almost anyone.
