Serotonin booster leads to increased functional brain connectivity

Telling us HN are doing "bad" won't help until you tell us what the bad is.

There was one episode where Huberman had a guy on talking about how young men should drink milk to maximize free testosterone and thus maximize “health” outcomes like height. There is a fairly substantial amount of research suggesting this isn’t actually a great idea more generally speaking because maximizing body size doesn’t have inherent benefits and could even have long term disadvantages for health outcomes. Further, drinking a lot of milk appears to be correlated with increased likelihood of developing cancer. And worse still, there are other foods which deliver the benefits of milk without the same disadvantages. Yet this odd little bit was accepted freely and without any criticality. Finally, maximizing height is kind of a culturally motivated desire in my mind. If you’re happy and healthy, who cares if you didn’t milk your growth spurts to the utmost degree? Is being 5’10” a shameful thing? Or even 5’6”? It struck me as so bizarre to hear someone in health still bent on growing kids larger. We’re not cattle. If we eat enough, we’ll grow enough. Let it be.

Attia has been slowly shifting over, but he’s been very pro animal-based foods in a field of research where the greater body of work indicates that these foods should be more limited or emphasized quite a bit less than he has. Or maybe this has changed quite recently. I know in the last few years he has begun to mention more often that eating plants appears to be critical to health and performance, but when I’ve listened in, he still heavily encourages eating more meat than seems necessary. It seems weird given he has a book about longevity now (I’m only half way through so maybe he’ll surprise me still) yet he doesn’t seem to be on the cutting edge of this research in regards to diet.

They’re very smart (smarter than I am by a wide margin) and probably very current in their research but I suppose it seems like they ignore certain areas of research. They seem a little “old fashioned” at times when it comes to diet in particular.

I’m not saying people should never eat meat. It’s about moderation. Attia also emphasizes consuming protein in ways that a lot of research doesn’t support, but I’m not in the field so what the hell. I don’t know who’s more correct.

The Dunning-Kruger effect.

> The Dunning–Kruger effect is a cognitive bias whereby people with low ability, expertise, or experience regarding a type of task or area of knowledge tend to overestimate their ability or knowledge.

This isn't always hypocrisy: There's a self-consistent idea here that you're missing: we recognize that psychology (and by extension psychiatry) is extremely hard. Human brains may be the most complex systems in the entire universe. I didn't get the feeling GP was claiming to be an expert, but rather he was claiming "there are no experts in psychology yet". I don't think that's as strong a claim as you seem to think. In fact I think most Ph.D.-level psychology researchers agree with just how tremendously difficult the subject is, and how little progress anyone is able to make.

It's consistent and defensible to believe both that it's absolutely critical for humanity to study its own brains, and also that we haven't done a good job at it yet. It's consistent and defensible to believe both that psychology researchers are smart, dedicated people doing admirable, important work, and also that they have really not made anywhere near the kind of progress to justify the level of confidence that pop-sci magazines, non-fiction writers, and podcasters exude. You don't need to be an expert in psychology to believe these things, either. You simply need to understand how deeply, fundamentally difficult the subject is.
