Why did you leave out the end of their quote about the metrics they use to judge their perception upon? "--as judged by things I build and people I interact with." I mean, I agree that sleep deprivation seems to induce temporary cognitive performance problems, but you're reinforcing a point that the parent seems to already understand -- that self perception is useless without objective performance metrics. Parent gave their opinion, reinforced by anecdotal evidence that they believe is an objective measure of their performance. Perhaps what should really be mentioned is that perhaps the metrics by which they are judging their cognitive performance are not as broad a test of those characteristics as one might believe.
