I had trouble initially understanding the level 2 vs 4 distinction. It read as if level 2 was a willingness to lie about object-reality to bring about specific consequences, while level 4 involved similarly lying about object-reality to bring about specific, selfish consequences.
This didn’t seem like the most meaningful distinction, so I wondered what I was missing. These comments seem to describe level 4 as also being concerned with lying about social-reality, which feels elegant? However, we should be thinking of level 4 as being concerned with both object- and social-level reality?
In either case, this piece felt easier to digest to a total newbie than your initial links, so thanks for that!
Anecdotally, since reading Guzey’s post a month ago, I cut down my sleep from ~7.25 hours (5 nights 7.5 hours + 1 night 6 hours) to around 6.33-6.5 hours (1 night 7.5 + 2-3 nights 6). I found that doing just 6 hours 4+ days in a row led to noticeable tiredness, although I never tried just pushing through and seeing if I can get used to it.
Regardless, with the current sleep load, I feel pretty good, and I plan to continue it. However, I have noticed some rare working memory slip-ups, maybe one per day or every other day, that I don’t think were as common before I dropped the sleep, although this isn’t severe enough to make me want to stop.
