  • A Monday Fave

    David does a superb job of explaining scientific information in an exciting and easily understood manner. I enjoy his guests and David's ability to communicate easily with his audience.

    Recently, in episode 160 regarding do we have a 'self,' David tried valiently to wrangle Sam Harris to discuss it rationally, but Sam continued to go off on gobbeldygook tangents, spouting his usualy lines. Don't get me wrong. I subscribe to both Making Sense and Waking up. But one of these days, I wish Sam Har... more

  • Do not like EP164

    Your earlier episode described how people feel differently with in or out groups. I think that’s the skill developed for survival. This episode basically calls that as racist, it went too far.

  • Liked old episodes better

    I preferred the earlier narrated format—it was concise and engaging. I’d love to hear more episodes in that style. The newer interview-style episodes feel longer and less interesting.

Talking Points

Recent interactions between the hosts and their guests.

Ep167 "What Happens With Stone Age Brains + Godlike Tools?" with Steven Kotler
Q: What practical advice does Steven offer to young listeners about leveraging AI while preserving humanity?
Write and think first before relying on AI, use AI for feedback and testing, but always initiate thinking yourself to keep the associative cortex engaged and preserve creativity.
Ep167 "What Happens With Stone Age Brains + Godlike Tools?" with Steven Kotler
Q: What is flow and why is it important in this new era?
Flow is a state of deep engagement where focus sharpens attention, reduces stress hormones, and boosts productivity, learning, and creativity; it serves as an antidote to chronic overstimulation and threat-detection that accompanies rapid change.
Ep167 "What Happens With Stone Age Brains + Godlike Tools?" with Steven Kotler
Q: What does Steven see as the biggest mental shift needed as tools become more powerful?
A move from feeling that technology is something that happens to us to actively shaping and participating in its development; this involves maintaining agency, focusing on meaning-driven goals, and using curiosity to manage information overload without surrendering creative control.
Ep165 "What's a Doom Loop & How Do You Escape It?" with Jonathan Downar
Q: What future directions look most promising for interventional psychiatry?
The field is moving toward targeted circuit-based interventions, combinatorial approaches that boost plasticity (like d-cycloserine) with TMS, accelerated treatment courses, and psychedelic-assisted strategies, all aimed at durable, rapid relief and broader applicability across disorders.
Ep165 "What's a Doom Loop & How Do You Escape It?" with Jonathan Downar
Q: How do interventions like TMS or deep brain stimulation help break these loops?
Interventions can recalibrate the balance between excitatory and inhibitory activity within key brain networks, effectively interrupting the loop, restoring plasticity, and allowing the brain to exit the stuck state and re-enter a more flexible pattern of activity.
