  • Podcast awesome… Eric Weinstein, unbearable

    I love this podcast and generally like the guest that Dr. Eagleman interviews. The conversations are informative and typically well balanced between more dense jargon and everyday language. However the February 2026 episode with Eric Weinstein was so hard to listen to because Weinstein seems so pretentious, condescending, and out of touch with what it means to be a “good person”. His perspective on Jim Watson suggests that he looks up to Watson even though Watson is a terrible human. Weinstein s... more

  • Painfully annoying bg music

    Just listened to the Sam Harris interview and found it almost impossible to listen to due to the horrendous music playing in the background. Why, oh why, would anyone feel the need to ruin a perfectly good podcast by playing bad music over the guest’s voice?

Talking Points

Recent interactions between the hosts and their guests.

Ep148 "How can we improve political dialog?" with Saul Perlmutter
Q: How can we teach the public to think more scientifically about uncertain problems?
By adopting the scientific mindset—probabilistic thinking, openness to being wrong, and iterative updates—rather than dogmatic certainty, and by creating educational and institutional structures that encourage deliberation and critique.
Ep148 "How can we improve political dialog?" with Saul Perlmutter
Q: What did the moment of dark energy and accelerating expansion feel like intellectually for Saul?
Saul describes the long, patient process of data sharpening over months, recalibrating, and gradually accepting that the expansion was accelerating, a shift that required humility, persistence, and a willingness to update beliefs.
Ep145 Why do we compulsively click on ragebait? with Angele Christin
Q: Tell us about rage bait and how it differs from traditional clickbait?
Angele describes rage bait as a broader, negative-arousal tactic that provokes anger or disgust beyond simple sensational headlines, including extreme examples like provocative cooking videos, and explains how creators use it to maximize engagement and revenue.
Ep145 Why do we compulsively click on ragebait? with Angele Christin
Q: How do the algorithms that we're surrounded with shape our lives?
Angele explains the shift from human signals to algorithmic signals, the rise of real-time dashboards in newsrooms, and how engagement metrics redefine what journalists and influencers consider valuable work.
Ep144 "How do things last?" Part 2: Millennia with Alexander Rose
Q: What role does storytelling play in the survival of institutions, and can you give an example of how narratives support longevity?
Storytelling anchors an institution's identity and purpose across generations, guiding decisions and legitimizing succession. An example is the Keeper of the Fabric in English cathedrals who preserves architectural history as a living narrative, ensuring changes are understood within a coherent story of the institution.
