While this blog post and reading about his opinions may be interesting, ultimately it's an opinion piece and I strongly dislike when people write opinion pieces and make it sound like they did a study in the title!
For all we know, he may be completely wrong! Maybe he is the outlier and people generally, in fact do perform more "focused work" than two hours a day...
Maybe he isn't overly enthusiastic about his work place, maybe he is in a remote work environment where he isn't inspired to work more efficiently through his peers. Maybe there is a little of everything and he's just trying to warrant this one hour focused work days through "insights".
The reason I'm questioning this is because I have procastrination issues at work and take several short mental breaks, but even I, once I get going and in "the zone" (often later in the work day), I can often do focused work at least twice as long as him. He really gives nothing to go by as for his bold title, which I ask why it's not at least the more undeniably accurate: "I don't work as much as you think".
The OP does mention "being in the zone" as a possibility. He just says that it's rare, inherently not applicable to many kinds of work, and requires optimal conditions that generally don't apply. It's very much the exception, not the rule.
