Episode 84: Codices de Moribus Scientificis - II
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.

Episode 82: Scientia: Nova Aetas Aurea
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 Is the linear model from basic research to application indeed outdated?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).

Episode 80: Intelligentia Artificialis
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? Enjoy.

Episode 77: Miscitatio
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).
