Yet the last two decades have seen the development of a sweeping conflicts of interest movement aimed squarely at curtailing academic/industry biomedical research collaborations and restrict- ing membership on government scientific advisory boards to researchers associated with industry. Conflicts of interest activists assert that ties between researchers and industry are harm- ing patients and consumers, undermining public trust in research, food safety and envi- ronmental regulation and boosting the costs of medicine and other products. As evi- dence, they repeatedly point to the same handful of research “scandals” and have pro- duced a number of studies correlating industry sponsorship with favorable results in clin- ical research. In addition, the anti-industry activist groups are trying to exclude academic researchers who have any ties whatsoever to industry from government scientific adviso- ry boards. However, even the activists’ own flawed studies can’t demonstrate that indus- try “influence” is distorting the decisions made by those boards. The campaign to purge any experts with industry ties—no matter how slender—from advisory panels is chilling scientific debate and depriving regulators and the public of valuable insights. These conflicts of interest activists focus almost entirely on the alleged baleful effects of financial conflicts of interest while ignoring how other conflicts can bias scientific research and advice to government agencies. People are influenced by all sorts of inter- ests besides money. Why should having once consulted with Pfizer or DuPont disqualify a scientist from serving on a government advisory board or writing a review article in a scientific journal, while being a lifelong member of Greenpeace does not? And if owning $10,000 in Dow stock represents a potential conflict of interest, surely $10,000 in fund- ing from the Union of Concerned Scientists does too. Contrary to the claims of conflicts of interest activists, the overwhelming majority of patients and research subjects are not being harmed, public trust in scientists and scien- tific research remains extremely high, and new drugs not only save lives but money. CenterWatch, which tracks 59,000 clinical trials in the United States, found that indus- try-sponsored drug trials are in fact safer than those at academic institutions funded by government. Polls regularly show that physicians and scientists are two of the most trust- ed professions. In fact, a recent poll found that three-quarters of cancer patients would have no qualms about enrolling in a study of a treatment sponsored by a company in which a researcher owns stock or from which he/she receives royalties. And finally, econometric research shows that newer drugs, rather than increasing overall medical costs (and thus arguably being foisted in a fraudulent fashion on a cash-strapped public), reduce other medical expenses by a factor of five.1 4 The current obsession with conflicts of interest is not harmless. The activists have pro- voked the development of unnecessary and complex academic regulations and restric- tions that are interfering with the speedy translation of scientific discoveries into effec- tive treatments and new products and technologies. Instead of improving public health or making our environment safer and cleaner, the activities of conflict of interest activists are harming them. Researchers are abandoning universities and some are even leaving the country for locales in which academic-industry collaboration is encouraged rather than denigrated and penalized. Government agencies are being denied access to sound scientific advice, which distorts regulatory priorities, risks lives and raises costs. When abuses have been uncovered, private entities including journals, universities and scientific professional societies have adequately addressed them. Such private solutions include the advent of permanent online peer-review of scientific studies and the require- ment by scientific journals that all clinical trials be registered. These private efforts are undercutting the campaign by activists to have Congress enact onerous conflicts of inter- est regulations. The plain fact of the matter is that there is very little evidence that alleged conflicts of interests are significantly distorting scientific research, harming consumers and
