I agree with the general sentiment of this sort of objection, but where it goes off the rails is the generalization to all sorts of modeling. If you think the model and it's assumptions are wrong why not go build a better model? That's the whole point of the scientific method after all.

- yorak 8y agoFrom how I see it the conflict is not technical but ideological. Or, in technical terms, what is the objective?: for Forrester and Collins this seemed to be increasing the economical growth of the city and managing KPI (crime, poverty etc.). Baker on the other hand considers also human dignity and our responsibility of keeping a fellow human fed, under a roof, and safe and does not ignore the externalities of the decisions.
