Cecilia Tomori, "Scientists: don’t feed the doubt machine", Nature 11/2/2021:
Throughout the pandemic, I’ve been saddened at how science has been hijacked. Arguments around herd immunity exemplify this: proponents claimed that acquiring immunity by infection was fine for most people and also that communities were well on their way to achieving herd immunity. The messages downplayed dangers for those with high risks of exposure or severe illness. Technical arguments over infection rates silently cemented the assumption that disabled or immunocompromised people did not merit collective protective action; nor did the workers whose jobs required dangerous public contact.
Although many scientific champions did provide appropriate context, I watched several respected colleagues step into debates on when, or if, society would reach herd immunity without realizing that the discussion was not simply a scientific debate. Their too-narrow focus unintentionally helped to promote controversy and doubt, and that ultimately impeded an effective public-health response. The same happened around mask use, vaccination and school policies. This helped to shift public opinion on which public-health measures were ‘acceptable’: the fewer the better.
The field of agnotology (the study of deliberate spreading of confusion) shows how ignorance and doubt can be purposefully manufactured. Famous scholars include David Michaels, Marion Nestle and Naomi Oreskes. In September, Katharine Hayhoe, chief scientist at the Nature Conservancy, a non-profit organization based in Arlington, Virginia, quoted environmentalist Bill McKibben on Twitter in regard to climate change: “We spent a long time thinking we were engaged in an argument about data and reason …. But now we realize it’s a fight over money and power.” Hayhoe elaborated: “‘Objections’ were always, entirely, professionally, and verrrry cleverly couched in scientific terms. They [industry] focused their lasers on the science and like cats we followed their pointer and their lead.” Some elements of manufactured doubt in this pandemic might seem fuzzier, especially when vested interests are not always clear. Nonetheless, the same lessons apply.
