Rapid prototyping works well in engineering, because you can test for faults quickly.

But transferring engineering practices into politics - which is not really new, "social engineering" has emerged again and again since the Enlightement Era - is usually a disaster.

In social contexts, people often cannot agree on what even constitutes a "fault" and how to measure outcomes. Individuals will adjust their behavior (unlike, say, a valve in a rocket engine, which can't consciously decide to sabotage the flight) and the systems tend to have long feedback loops.
