The Matter of Facts

Skepticism, Persuasion, and Evidence in Science

By Gareth Leng and Rhodri Ivor Leng

How biases, the desire for a good narrative, reliance on citation metrics, and other problems undermine confidence in modern science.





How biases, the desire for a good narrative, reliance on citation metrics, and other problems undermine confidence in modern science.

Modern science is built on experimental evidence, yet scientists are often very selective in deciding what evidence to use and tend to disagree about how to interpret it. In The Matter of Facts, Gareth and Rhodri Leng explore how scientists produce and use evidence. They do so to contextualize an array of problems confronting modern science that have raised concerns about its reliability: the widespread use of inappropriate statistical tests, a shortage of replication studies, and a bias in both publishing and citing “positive” results. Before these problems can be addressed meaningfully, the authors argue, we must understand what makes science work and what leads it astray.

The myth of science is that scientists constantly challenge their own thinking. But in reality, all scientists are in the business of persuading other scientists of the importance of their own ideas, and they do so by combining reason with rhetoric. Often, they look for evidence that will support their ideas, not for evidence that might contradict them; often, they present evidence in a way that makes it appear to be supportive; and often, they ignore inconvenient evidence.

In a series of essays focusing on controversies, disputes, and discoveries, the authors vividly portray science as a human activity, driven by passion as well as by reason. By analyzing the fluidity of scientific concepts and the dynamic and unpredictable development of scientific fields, the authors paint a picture of modern science and the pressures it faces.

  • “Science, one of humanity's greatest achievements, is laden with philosophical, sociological, and psychological complexities that we mostly ignore. By bringing these complexities out into the open and showing us how to embrace them,The Matter of Facts stands to make us better at both doing science and learning from it.”
