They aren't arguing entirely from anecdotes, they are using them to illustrate the point mostly. They are writing for a broad audience of non-scientists, which they've used as an excuse to exclude references from passages like the above, perhaps justifiably.
Ah, but we would need to know the parameters and conclusions of these studies to know if the author was utulizing the data and findings correctly or if he is using it in a biased manner.
Assuming, he references the generality of the studies appropriately (abandon the quest to minimize sleep unreasonably). Then the discussion should cater towards the differences between unreasonable sleep deprivation expectations brought on unwillingly and its toll on the mind vs. sleep deprivation willingly done due to a personal will to finish a project or continue a streak of creativity, etc.
If you want to know, raise some funding and do a meta-study. This was just an article to provoke thought among business-types (being in the Harvard Business Review) - If you want to find The Truth then you can, the universe is right there in front of you to measure.
(I'm only half joking - if you put a proposal for a meta-study about this research up on Kickstarter, I will back it.)
