Facile, shallow, and only supported by only a modest amount of evidence—but as a confirmed night-owl I want to believe it, so it must be true. <grin>
Joking aside, though, I’m happy to see more articles about chronotypes and personality in the media lately—the long social dominance of early-bird values seems to be waning. Perhaps I’ll one day get to work in an office free from social jet-lag.
I’ve read about this fairly seriously, starting with William Dement’s The Promise of Sleep a decade ago. The best resource, though, is a somewhat more academic book (still quite approachable) by Till Roenneberg, called Internal Time. Recommended.
