Hey Guzey, thanks for hopping in. I like your blog.

Walker's book is sloppy. The graph you mention last is egregious. No disagreements here. Honestly I agree with you at least partly on all of your points.

So why did I miss your points? I was trying to give better evidence/info relevant to the topic of each point. My hope was people would read it and continue to respect sleep as an open and very interesting biological question. Maybe it came off as ignoring the points. I understand that. But honestly I don't care about Walker that much - I care about sleep. Its really weird, and we don't understand it.

Out of curiosity, what is your current stance on sleep?

EDIT: after re-reading this comment, I realized it might seem a bit disingenuous, because I did criticize your arguments as bad faith. Clearly I care a little about your take-down of Walker.

I said this because you found claims in Walker's book, found errors in his evidence, and then denied the general claims in your bold-font headings. It seemed like you were dismissing the putative importance of sleep along with dismissing Walker the author. I felt this was uncharitable to the topic, so I gave you the "bad faith" charge.

Got it. I apologize if my tone was too harsh. I do stand by all of the bold-font headings, but yes, primarily the post is directed at Walker.

My current stance on sleep is that we don't know much about it and we don't know much about how much exactly we need to sleep. I'm collecting some notes on sleep (very preliminary so far) here: https://guzey.com/sleep/

Oh its alright, I didn't feel attacked.

If you're curious, here's another GWAS open-access paper on sleep: https://doi.org/10.1038/s41467-019-08917-4. Its self reporting, but its tricky to do EEG or some other technique on half a million people. Also this associated portal is cool: http://sleepdisordergenetics.org/home/portalHome
