I’m naturally a night owl. I rarely go to bed before 2 AM and then sleep until 10 AM or so in the morning. As a result, I’ve been sleep deprived for most of my life prior to retiring at age 38, with the exception of the 3 years I spent in college where I rarely attended class.
The working world favors early risers, but savvy night owls can game the system to their advantage.

What does better cognition mean in this?
{{ Participants had completed various cognitive tests including memory, reaction time, and fluid intelligenceTrusted Source. }}

What time of day did they take those tests?
I’m guessing during clinic hours, 9AM to 5PM. I doubt they had someone banging on a door at 2AM looking to administer a cognitive test.
Ever once and a while a Door Dash driver rings my doorbell at 2AM, likely because my home is one of the few with the lights on at that hour. I counsel them, that it’s not my order, and that I’ll never be wealthy enough to afford Door Dash’s outrageous delivery fees.
My dog regularly pulls abandoned food delivery orders out of the shurbery on her morning walks.

It looks like the tests were taken whenever the participant wanted via computer. FWIW, the average age was 71.

That’s good. If they had 24-hour access to the test, I suspect that the participants were only doing so when they were most interested in taking the test and at peak cognitive ability.

Brain connectivity in the regions of the brain that can predict better performance and lower sleepiness were significantly higher in larks at all times, “suggesting that the resting state brain connectivity of night owls is impaired throughout the whole day.” [end quote]
It would be interesting to see whether either of these studies could be independently replicated.
