> The thing he lacks is the ability to summarize.
That's a feature, not a bug.
Discussing these topics for hours and hours is the primary draw of this type of info-tainment. The basics of healthy living and even 80-90% optimal diet/exercise could be summarized in a 1-hour podcast. The average Huberman listener would likely benefit more from improving sleep, exercise, diet, and other basics (which he does cover, but it only goes so far) than spending 4 hours learning about the latest round of supplements and associated research.
But summaries don't get people excited, nor do they prime people to feel the placebo amplification effect (or just raw placebo effect) of the latest supplement they just spent 4 hours hearing about.
"Try taking ____ supplement. It has shown to improve ____ in mice." is boring and doesn't inspire a lot of confidence.
Four hours of excited discussion about molecules and scientific lingo feels like real science. It's hard to argue with someone so invested in a topic that they spend hours and hours talking about it. This supplement must work and I must use it if I want to get ahead. That's the goal of these long podcasts.
