On the Fringe

Outline

On the Fringe (2021) explores the blurry line between real science and pseudoscience. Michael D. Gordin explains why it is so hard to define exactly what counts as science, and looks at historical examples of ideas that were once taken seriously but later rejected. The book helps readers think more carefully about scientific claims, expert authority, and how knowledge is tested and accepted.

• The line between real science and pseudoscience is blurry, and it is hard to define exactly what counts as science.
• Some ideas that were once taken seriously were later rejected, and history offers many examples of this.
• Thinking carefully about scientific claims means asking how a claim was tested, not just who is making it.
• Expert authority matters, but readers benefit from understanding how knowledge is tested and then accepted.
• Learning why pseudoscientific beliefs spread helps you evaluate evidence and question doubtful claims more calmly.

Michael D. Gordin is an American historian of science and professor at Princeton University. He studies the history of modern science, including chemistry, physics, and the ways scientists communicate and define their fields.
