Summary

An argument that what makes science distinctive is its emphasis on evidence and scientists' willingness to change theories on the basis of new evidence.

Attacks on science have become commonplace. Claims that climate change isn't settled science, that evolution is “only a theory,” and that scientists are conspiring to keep the truth about vaccines from the public are staples of some politicians' rhetorical repertoire. Defenders of science often point to its discoveries (penicillin! relativity!) without explaining exactly why scientific claims are superior. In this book, Lee McIntyre argues that what distinguishes science from its rivals is what he calls “the scientific attitude”—caring about evidence and being willing to change theories on the basis of new evidence. The history of science is littered with theories that were scientific but turned out to be wrong; the scientific attitude reveals why even a failed theory can help us to understand what is special about science. 

McIntyre offers examples that illustrate both scientific success (a reduction in childbed fever in the nineteenth century) and failure (the flawed “discovery” of cold fusion in the twentieth century). He describes the transformation of medicine from a practice based largely on hunches into a science based on evidence; considers scientific fraud; examines the positions of ideology-driven denialists, pseudoscientists, and “skeptics” who reject scientific findings; and argues that social science, no less than natural science, should embrace the scientific attitude. McIntyre argues that the scientific attitude—the grounding of science in evidence—offers a uniquely powerful tool in the defense of science.

Welcome to PFC's monthly lecture night series!

Each month (with the exception of August and December) we feature a presentation/lecture on a variety of topics. Our primary focus is on science, but we also have talks on skepticism and humanism and beyond. We try to structure the meetings to begin with a presentation that leaves time for great discussions and Q&A sessions afterward. We try to post the topic and speaker bio as soon as that information is known -- please check back soon. If you have speaker suggestions and/or ideas that are in keeping with our mission, please feel free to email your suggestions to info@pghfreethought.org.

See you there!

P.S. We usually head to Ali Baba's on nearby Craig Street at 5:30 p.m. for a pre-lecture or pre-movie dinner. Please leave a comment below if you are coming to dinner so we can include you in the reservation. Thanks!
