While it is good to be skeptical, the book really goes in depth and makes a compelling case. I also believe sleep is one of those areas that it is better to err on the side of getting the recommended amount. “If sleep does not serve an absolutely vital function, then it is the biggest mistake the evolutionary process has ever made.” - Dr. Allan Rechtschaffen.

They are all observational studies, usually with small cohorts. Same problem with nutrtitional science and psychology. History tells us again and again these results are biased, unduly influenced by the investigators and often overturned (eg Thinking Fast and Slow).

I knew big sleep was behind this

There is being skeptical and then there is baseless, conspiratorial cynicism -- the kind that usually makes you hurt yourself.

And there's shaming people for having a different opinion than the majority.

Opinions do not gain credence just because you hold them and they do not gain credence or viability just because they're contrarian. No one is shaming it by the fact that it's a minority opinion, it's just a baseless silly opinion to have.

Don't be disingenuous.

> it's just a baseless silly opinion to have.

Sounds like shaming to me.

No it doesn't, and it's still wouldn't be shaming for the reason you outlined. Your entire statement is pointless if you have to crawl all the way back to a single verb to make it relevant.

You sound mad.

Well hopefully that hasn't affected you too much.

Your comment is ridiculously over the top. Not sure why you are getting so emotional about a nicely packaged bunch of observational studies.

Who's being emotional here again?

I know I'm a little late to the discussion, but I think your comment might be more well-received if you were to provide evidence to support your claim about the author's financial incentivization. After reading your comment, I looked briefly at the linked article and found the author's wikipedia page. It seems as though his primary product doesn't involve sleep. Are you saying he's financially incentivized via ad revenue from his blog posts on sleep?

In any case, I guess what I'm saying is you seem to have researched the topic and your spending an extra minute or two giving a few more details will probably save a bunch of other folks ten times that, in aggregate.
