Nullius in Verba
Nullius in Verba is a podcast about science—what it is and what it could be. It is hosted by Smriti Mehta from UC Berkeley and Daniël Lakens from Eindhoven University of Technology. We draw inspiration from the book Novum Organum, written in 1620 by Francis Bacon, which laid the foundations of the modern scientific method. Our logo is an homage to the title page of Novum Organum, which depicts a galleon passing between the mythical Pillars of Hercules on either side of the Strait of Gibraltar, which have been smashed by Iberian sailors to open a new world for exploration. Just as this marks the exit from the well-charted waters of the Mediterranean into the Atlantic Ocean, Bacon hoped that empirical investigation will similarly smash the old scientific ideas and lead to a greater understanding of the natural world. The title of the podcast comes from the motto of the Royal Society, set in typeface Kepler by Robert Slimbach. Our theme song is Newton’s Cradle by Grandbrothers.

Episode 25: Reverentia Ad Auctoritatem
Friday Jan 12, 2024
Friday Jan 12, 2024
In the first episode of 2024, we discuss the double-edged sword: reverence to authority. Should scientists respect others on whose shoulders they stand? Or should they be wary of appeal to authority? How should scientists deal with other sources of authority in science, like for example, the government or academic societies? And how can we differentiate true expertise from mere authority? Enjoy.

Friday Dec 01, 2023
Friday Dec 01, 2023
In today’s episode, we discuss the role of mentorship in academia. What are the characteristics of a good mentor-mentee relationship? What are the qualities of good mentors and good mentees? Does mentorship play a role in the development of scientific knowledge? And could mentors and mentees benefit from couples therapy?

Episode 21: Verifica Sed Confide
Friday Nov 17, 2023
Friday Nov 17, 2023
In this episode, we discuss the role of trust in science. Why should we verify but trust other scientists? What are the prerequisites for building trust within the scientific community? Who is ultimately responsible for verifying our claims and practices that bolster those claims? And should we give personality tests to everyone who enters academia?

Episode 20: Recensio Aequalium
Friday Nov 03, 2023
Friday Nov 03, 2023
In today’s episode, we discuss the peer review process---its history, its present, and its future. How does peer review work? How long has it existed in its current form? Should reviews be open and signed? Should reviewers be paid for their hard labor? Should we just abandon the peer review process, or does it have a positive role to play?

Episode 19: Quantifauxcation
Friday Oct 20, 2023
Friday Oct 20, 2023
In this episode, we discuss Quantifauxcation, described by statistician Philip Stark as “situations in which a number is, in effect, made up, and then is given credence merely because it is quantitative.” We give examples of quantifauxcation in psychology, including errors of the third kind. We spend the second half of the podcast discussing how to develop quantitative measures that are meaningful and bridge the divide between qualitative and quantitative observations.
