Crows are intelligent birds and learn quickly – even from each other.In Sweden, they are used to collect cigarette butts and bring them to a machine that automatically rewards them with peanuts.

The issue is the crows are going to learn about this, and start just fishing rubbish out of bins, because it’s the easiest way to get their reward.

There was once a Parisian dog who kept trying to push children into the Seine, because he had learned that if he ha saved a drowning child he gets tons of rewards.

This phenomenon is called Perverse Incentive , also known as the Cobra Effect.

Fucking Cobra Kai

Is the firebug phenomenon part of this?
