Carl Bergstrom is a theoretical and evolutionary biologist and a professor at the University of Washington in Seattle, Washington. Bergstrom is a critic of low-quality or misleading scientific research. He is the co-author of a book on misinformation called Calling Bullshit: The Art of Skepticism in a Data-Driven World and teaches a class by the same name at the University of Washington. He and I talk about the importance of understanding what is being perpetrated around us and how to avoid falling into traps created by skilled bullshitters.
