Suppression of environmental health scientists: real-world examples as a basis for action

Pressures on epidemiologists, toxicologists, and on public health scientists to suppress their work are known to occur worldwide. In this article, we share six stories from environmental health scientists about the pressures they faced in their jobs after bringing public health problems to light. The method used to document each of the stories was to invite scientists who attended meetings of the International Society for Environmental Epidemiology to tell their own stories of having experienced research suppression. We then extracted the salient features of each experience into a coherent story, providing references as corroboration where possible. The specific purpose in going public with the six stories presented in this article is to open a conversation to better equip colleagues to stand up to pressures to suppress their work. By publicly sharing the pressures experienced by these scientists in attempts to suppress their scientific work, including intimidation, harassment, threats and/or bullying, other scientists may be better able to withstand such pressures. In the absence of a larger collection of stories, we are unable to identify common approaches taken against suppression. It appears that a focus on scientific excellence and tenacity are two major factors likely to have contributed to the ability to withstand pressure. We encourage others to tell their stories. Bringing examples of these instances to attention will make them familiar enough to be less intimidating should others experience anything similar. Additional documented experiences will expand the base of stories and thus help colleagues to withstand the pressures wielded by special interests. Shining a light on these pressures will remove barriers, not only to advancing the science, but also to protecting the public interest
