Nattväktarstatens effektivitet matematiskt modellerad

ScienceDaily skriver om en studie vid Universitat de Barcelona som kommit fram till att försök att reglera leder till minskad effektivitet:

In order to test their hypothesis that heavy handedness can lead to loss of control, the researchers used optical tweezers to grab hold of floating microscopic beads. They then dragged the particles back and forth in the fluid as they ramped up the intensity of the lasers that formed the tweezers. As they expected, increasing laser power provided an ever tighter grip on captured particles, but only up to a point. Eventually, ramping up the laser led to a poorer control of the particles, which jostled around more and more as the laser intensity increased.

Författarna sammanfattar:

The experiment was consistent with a simple mathematical model that the researchers suggest could be helpful in optimizing all sorts of systems, from high-resolution microscopes to managed ecosystems such as national parks. It could even help mathematically explain why overly strict social policies may lead to chaos and revolution, and how iron-fisted fiscal policies can potentially drive economic systems to ruin.
