    Episode 3: Confirmatio Praeiudicia

    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.

    Episode 2: Scepticismus

    Episode 2: Scepticismus

    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?

    Episode 1: Motivus

    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.

    Episode 0: Introductio

    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.
