Dunbar’s number is a suggested cognitive limit to the number of people with whom one can maintain stable social relationships — relationships in which an individual knows who each person is and how each person relates to every other person … By using the average human brain size and extrapolating from the results of primates, [Dunbar] proposed that humans can comfortably maintain 150 stable relationships.

Let’s stipulate that the “leader” of a “Dunbar Group” can effectively manage ALL of the group’s affairs. In our hypothetical community, “Dunbarville” (note that we’re doing a very Hobbesian “thought experiment” here), our leader – let’s call him Steve – can grasp the essentials of every issue facing the town. He doesn’t need to be an expert without portfolio. He doesn’t have to know all the ins-and-outs of, say, farming to be the effective leader of Dunbarville. However, he has to know that farming is a thing, the basics of how it’s done, understand the importance of well-maintained farms to the community, etc. Steve can delegate the management of Dunbarville’s kolkhoz to an experienced expert farmer, but Steve knows enough to be able to intervene effectively if the farm expert gets too big for his overalls.
Now consider what happens if Steve is any good at his job. Because Dunbarville’s kolkhoz is so well-managed, it can support a much larger population than 150. What does Steve do? Well, he knows that a population greater than 150 will be beyond his capacity to handle 100% effectively … but he also knows that forcing population restrictions on Dunbarville is the fastest way to get himself exiled, after which they’re going to have a baby boom anyway, so Steve does the best he can. In a few years he’s operating at 90% efficiency, then 70%, then 55%, because the community is simply growing too large for any one man to handle.
Now he has to delegate, and the delegation has to be permanent. Steve simply can’t keep up with everything that’s going on in the kolkhoz. So he delegates “kolkhoz management” to Gary. Gary’s not a bad guy – in fact, he’s the dude who managed the kolkhoz so well in the first place. But that task is, itself, now too big for even Gary to handle, so Gary hires some assistants. Worse, Gary knows he’s getting on in years, so to make sure the kolkhoz will keep working at peak, baby-boom-causing efficiency even after he’s gone, he sets up the Gary School of Farm Management …
And so forth, you get the point, we don’t have to run through the whole thing. That’s what I mean by “irreducible complexity” (IC). Once you clear the Dunbar Number, certain tasks have to be independently managed by cadres of experts who are only nominally answerable to the central authority. That’s where bureaucrats come in, and that’s where bureaucrats are good. Steve can’t manage ALL of Dunbarville’s affairs anymore, since it’s now a bustling community of 1,500, but he can manage the 150 bureaucrats who report to him. And since those bureaucrats are supervising only 150 people themselves …
Bureaucrats are, in effect, the re-imposition of a Dunbar Number on an increasingly complex society. When I say that the Roman Empire, for example, was under-bureaucratized, that’s what I mean. Maybe the Emperor had the good sense to limit his high officials to 150, but they had to manage 400 lower officials each, and each of those 400 were responsible for 20,000 peasants, or whatever the numbers actually were. That’s “irreducible complexity,” org-charts version. Unless you’ve got a perfectly balanced ratio of managers to managed, things are going to get very fuzzy at the edges, very fast … and that’s of course assuming complete competence on everyone’s part.
