Economists end up solving this problem by denying it (a mechanism that Stafford Beer looked at in detail, concluding that ignorance is a kind of information processing system of last resort). Where analysis fails, ideology steps in, and the solution the economists decided on was to fantasise an equivalent system for producers — a profit-maximising firm with an understanding of its market, a style production process and a manageable set of decisions. It ended up going disastrously wrong, but the original intellectual sin may have been the failure to respect the integrity of the black box.

Often, a core skill of middle management is the ability to manipulate the financial reports to compensate for a set of numbers that aren’t giving the right answer. Everyone who has put together a business plan knows that if you can’t fudge the key assumptions to justify the decision your boss wants to make, you don’t know enough about the business.

And this story repeats itself through the history of management science; almost every classic of the literature seems to have described a way of adapting systems to a more complicated world, and then to have become obsolete itself. If you look past the slogans and think about what things like ‘management by objectives’, ‘focus on core competences’ and so on actually mean, they are all different ways of advising executives to restructure their businesses so that they don’t generate complexity faster than it can be managed.

We’ve already seen how accounting systems can act as an information-reducing filter. It follows from this that the greater the emphasis placed on accounting-based targets set by the CEO, the greater the filtering effect.

Corporations are decision-making systems, not ‘intelligences’. They have homeostatic forces which aim to maintain their equilibrium, and higher-order decision-making systems which mean they are able to reorganise themselves in order to respond to shocks beyond the scope of anything anticipated when they were designed. To attribute motivation to them is to make assumptions about the internal workings of the black box — the original intellectual sin of cybernetic analysis.
