Yale experts offer thoughts on ‘Science Under Siege’

As thousands of scientists around the world prepared for the April 22 March for Science, a trio of top Yale professors shared their views in a Poynter Fellowship symposium on truth, trust, and science in the modern age.

Carl Zimmer, science writer and author of The New York Times column “Matter,” and Alison Snyder, science editor of Axios, moderated the discussion, “Truth in the Internet Age: Science Under Siege.” The event was held April 20 at Sheffield-Sterling-Strathcona Hall.

“We have a polluted scientific communication environment,” said panelist Dan Kahan, the Elizabeth K. Dollard Professor of Law and professor of psychology, during his portion of the discussion.

Kahan noted that for certain science topics, such as climate change, scientific information has become entangled with group identity, politics, and contempt for opposing viewpoints. Forcing people to choose between science and their group identity is the wrong approach to presenting scientific information, he said.

Instead, he offered, “find some basis for using what science knows that is completely independent from denying your group identity.”

Meg Urry, the Israel Munson Professor of Physics and Astronomy, said scientists and journalists must do a better job of communicating “the living, breathing thing that science is,” and tell the stories of how basic science has powered our economy and our technology for generations.

“The trouble is, the people making decisions don’t always make those connections,” Urry said.

There is also a generational divide among scientists about the role of communications, she added. Younger scientists tend to see communications as a vital part of their work, while older scientists sometimes see it as an afterthought, she said.

David Hafler, the William S. and Lois Stiles Edgerly Professor of Neurology and professor of immunobiology, and chair of the Department of Neurology, said one of his jobs as a physician is to be an educator.

Part of that education, Hafler said, is to explain more effectively that science is about models that are refined and improved. Science, he said, is about probability rather than certainty.

“We’re doing things now (in medicine) that were unimaginable six months ago,” Hafler said. “That’s the narrative we need to tell.”

The panelists warned there is a risk that scientists being more vocal about issues may inadvertently widen political divisions in the country, but noted there are opportunities for positive change, as well.

“If it remains a conversation about what science is and what it does for the world, and stays away from political finger-pointing, it could be an educational moment,” Urry said.

In the era of "post truth" and fake news, what are the implications for science and the communication of science?   When is a fact a fact? What is the relationship between truth and the pursuit of scientific knowledge? Two days before the March for Science, these and other questions related to science and the communication of science were explored and debated in a forum featuring interviews with three esteemed members of the Yale faculty: Dan Kahan, the Elizabeth K. Dollard Professor of Law and professor of psychology; Meg Urry, the Israel Munson Professor of Physics and Astronomy; and David Hafler, the William S. and Lois Stiles Edgerly Professor of Neurology and professor of immunbiology and chair of the Department of Neurology
