Note that our work is not a test of the KonMari method per se but rather an investigation of ideas—on dis/order, waste aversion, and selection/rejection (as these quotes illustrate)—inspired by her writing and the surprising lack of research on downsizing."

    Episode 70: Scientia Tacita

    In this episode, we try to make the concept of tacit knowledge explicit. How much of our scientific knowledge depends on knowledge that we can't communicate directly? How can we replicate studies, if they might rely on tacit knowledge? And why has the concept itself not been made more explicit in the last 45 years? Enjoy.

    Episode 64: Scientia de Scientia - I

    In the first part of this two-part episode, we explore the foundations of metascience—what it is, how it relates to and differs from the history and philosophy of science, and why understanding its philosophical roots matters. We also discuss the “four pillars” of the field and whether formal experience is necessary to contribute meaningfully to metascientific work.
