I did not read the article (what did you expect, we are on HN ;) Anyway, my experience has been a little bit different. I would summarize it as "good life, good sleep, good learning". And yes, order matters. The fact is that recently I was completely in my midlife crisis and was at probably 50% of my mental stamina (memory loss, lack of interest, poor focus, and insomnia ). I was ok with the fact that I was getting o…

I strongly believe it's a positive feedback loop: "good life, good sleep, good learning, good career, good friends, good family, good home, good legacy, good politics"

It comes off the inspiration from my First Big Personal Project: https://adequate.life

Wait, so I am not the only one who almost never read articles, but spend 30 minutes on reading their comments?

I usually start with the comments to see if it's worth reading, often it isn't, but the comments were interesting all the same.

That said, I have not tested it empirically myself so I think that is cause for moderating my claim -- I place a high value on empirically-tested knowledge. Take my claim as partially withdrawn.

> Here's the basis of that claim [1].

Based on a skim of the paper, this experiment seems to only plan out how individuals study material on the same day, not distributed over a period of time that lasts multiple days.

In order to test how much of the material was retained in long-term memory, they tested the subjects on the material again after one week.

Spaced Repetition software (anki, mnemosyne, and supermemo) will distribute the learning across multiple days regardless of the algorithm they use. I don't believe the paper cited is using the same testing method that SRS systems use.

Piotr Wozniak (the creator of Supermemo) has collaborated on a couple of papers regarding this topic. I have not found many researchers who are studying it and creating algorithms in quite the same way.

There are a few papers cited in a blog post / self-published supermemo wiki here [1] that discuss a proposed two-component model of memory that explain in greater detail why learning on increasing intervals of time (days, not in the structure of repetitions on the same day) can lead to a higher stability of memory.

I think that's one of the things I find most appealing about his writings in general. Most people don't go to global optima solutions because there are various constraints while Woz just does not bother. These suggestions cannot be taken to their conclusions in many cases but I think they are still good inspiration to try.

It'd be a lot better if the article wasn't filled with ad nauseam scaremongering about how poor sleep causes every form of human suffering if not outright death. Many of his suggestions are simply not actionable to many people in the strongest sense of the term. Letting children sleep longer is simply not legal in (I assume) most jurisdictions. He mentions off-hand that co-sleeping is not recommended by most pediatri…

Which claims run contrary to established science? Are the claims you mention that are established agreed upon unanimously, or are there multiple models comprised of competing evidence?

OP author is usually biased in one way or another (just like any of us). Reading comments you're pretty much guaranteed to view the problem from multiple angles. When I feel adventurous I read the article first trying to anticipate what the comments will be. When I feel lazy I skim the comments first, then read the article with the grain of salt ready (or not at all).
