Scott: Come On, Obviously The Purpose Of A System Is Not What It Does

astralcodexten.com

This made me reflect that I hadn't actually thought critically about the phrase (at least, commensurate to how often it's used). For fun, if you think the purpose of a system is what it does, write what you think that means, before reading Scott's critique, then write if you've updated your opinion. For example: I think it's a useful way of re-framing obviously dysfunctional systems, so as to analyze their dysfunction, but Scott is persuasive that it's not a good means of understanding systems, in general, so people should be more cautious about adopting this framing and using the phrase, rhetorically.

For fun, if you think the purpose of a system is what it does, write what you think that means

Systems are a product of human will and action. No system continues if it is not fed and maintained by active human effort. "Systems" do not ever do things on their own; the people who control and operate them are responsible for all outcomes.

If you observe a novel system and wish to understand it, look at the outputs it produces. Those outputs are what the people feeding and maintaining the system consider sufficiently acceptable to continue feeding and maintaining it. Thus, they are a reasonable approximation of the purpose of the system, and certainly offer a far better understanding of that system than theoretical claims that diverge significantly from observed outputs. If people have been feeding and maintaining a system with Output Z, all the while claiming the purpose of the system is output A, their claims probably do not contain useful information and should be discounted. It doesn't really matter if they're lying or simply incompetent; they probably do not have useful information to offer.

The longer the system has been fed and maintained, the better this heuristic works.

I'm reading the article. I'm not impressed so far, but perhaps it gets better.

[EDIT] - That was an uncharacteristically-short post, and it did not get better.

I think it’s useful as a heuristic. It the system in question is always getting a supposedly wrong result, it’s perfectly reasonable to say “that wrong result is the point.” If you have a system that is supposed to produce widgets, but instead the people who run it produce nothing but paperwork on the impacts the widgets will have, then the point is tge paperwork and not the widget. The point of most iPad games is not to be fun, the point is to show ads and frustrate the player into spending money.
