Given that this includes rat and mouse studies, it seems like this theory is more around the idea that criticality is a characteristic of how brains work in general, not that human brains hit criticality as a peculiarity of our particularly high intelligence
So that article does not support the "overclocked" thesis, rather that this critical state is needed for optimal performance.
I do agree with the original sentiment, that we are not exactly well adapted to our environment. Or our environment to us, cause this is the main point I think that is missing from this discourse about adhd or other modern frequent mental conditions: too high expectations. Cause of our inherent human narcissism we think we are more attentive and logical than we actually are, so naturally those with lower attention become noticeable first. Or whatever other metric we are measuring leading to whatever condition (depression, autism, ...). At least that mechanism seems underreported in the public. Anyone familiar with how this is viewed on in academia?
