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.

In our third episode, we discuss confirmation bias, which affects not only how scientists generate and test their own hypotheses, but also how they evaluate the scientific evidence presented by others. We discuss guardrails against confirmation bias that are already in place, and others that could potentially improve scientific practice if adopted.

In our second episode, we discuss the role of skepticism in science, a topic that relates closely to the title of our podcast. Given that the scientific enterprise is essentially an exercise in organized skepticism, how can we maintain a healthy amount of skepticism while also ensuring that scientists don't slip into cynicism or nihilism?

In our first episode, we discuss a quote from the preface to The Instauratio Magna (of which Novum Organum is a part), in which Bacon claims that scientists should be motivated to do science for the betterment of mankind, and not for personal motives like fame, fortune, or even fun.
Here is the tweet (by Heidi Seibold) on academia not being aligned with good scientific practices.

In this introductory episode, Daniël and Smriti share which podcasts they like, why they are starting their own, and how their connection to each other is also tied to podcasting. They also talk about the theme of the podcast, which is inspired by Francis Bacon’s delineation of the scientific method 400 years ago.
