In today’s episode, we discuss the classic 1959 Rede Lecture by scientist and novelist C. P. Snow. We reflect on whether there is still a divide between the humanities and the sciences, how important it is to be educated in both, whether the humanities and the sciences care just as much about the truth, whether scientists need to know Shakespeare, and what the second law of thermodynamics is about.

In this two-part episode, we examine scientific codes of conduct, using the Netherlands Code of Conduct for Research Integrity as our primary example. We discuss why such codes are necessary, where their guiding principles come from, and how (and whether) they are enforced. We also discuss many of the standards of good research practice derived from said principles.

In this episode, we will reflect on how governments should support science, from the 1945 policy report Science: The Endless Frontier by Vannevar Bush, and then move on to the recent policy document by the Trump Administration 'Science: A New Golden Age'. We reflect on what we like about the policy report and what we like less. Is the linear model from basic research to application indeed outdated? Are metascience units a good idea? And will AI accelerate and radically transform how we do science? Enjoy. Shownotes: Bush, Vannevar. (1945).

In this episode, we will discuss multiverse analysis–what it is, why we use it, and how we should use it. We also discuss many analyst projects, and Daniel's new preprint on multiverse analysis.    Shownotes Auspurg, K. (2025).

After a short break due to busy calendars, we are back to discuss the role automation and artificial intelligence can play in science. Is AI evil, or does it just amplify the problems that were already present in science? Can automated AI driven checks help scientists to improve the way they work? If so, where are these tools helpful, and when?

In this episode, we discuss the problem of miscitation. How often are citations to the scientific literature outright misleading? Do we really need to spell out that people  are supposed to read what they cite? What can we learn from other fields? Or should we just live with the fact that a decent percentage of citations in the literature are wrong? Enjoy.    Careless citations don't just spread scientific myths – they can make them stronger (Nature) Cobb, C. L., Crumly, B., Montero-Zamora, P., Schwartz, S. J., & Martínez Jr, C. R. (2024).

In this episode, we discuss the problems associated with vague concepts in psychological science. We talk about the jingle-jangle fallacy, the trade-off between broad concepts and more precise concepts, if we should generate databases of conceptual definitions, and how the reward structures can get in the way of specifying concepts clearly.   Shownotes Aikins, H.

In this episode, we continue our discussion of scientism. We talk about 6 problems with scientism that have been raised by Susan Haack, if we should feel bad about having some sympathy for scientism, and whether the contributions of all scientifici disciplines deserved the label of 'knowledge'.

In this two-part episode, we delve into the topic of scientism. Is science the best way to generate knowledge? Or are we giving too much deference to science if we believe this? In this first part, we discuss what scientism is, what - if anything - is wrong with scientism, and whether it is bad to be a scien-ti-sim-ist?   References:   Haack, S. (2012).
