Agreed.

Most people are not self reflective reflective enough to notice. Need to trust the studies.

Far more plausible than the AI ideas.

I find it far more likely these are smart people running without oversight for years pre-COVID, relying on being smart at 2am change windows. Now half or a full std. dev. lower on the IQ scale, hubris means fewer guard rails before change, and far lower ability to recover during change window.
