Until schoolkids repeatedly mash the frowny face button for lulz.

We need version numbers for game-theoretic universes, e.g. the effects of companies which launch into a market whose assumptions and practices will soon be overturned by said company.

The second-order feedback loops are adversarial (kids, competitors, city-states, policy) and subject to data analysis, but the public is more likely to receive marketing narratives than peer-reviewed scholarship.

I always press the frowny button in grocery shops, not necesarily because there were long lines or because the shelves weren't stocked adequatly, but if I press the frowny button I assume the place will get even better.

I disagree with those buttons because you can't really find the cause of a problem in a giant macihnery with just a single output. So the feedback is probably close to useless.

The buttons are generally used to punish the clerks on duty. All you are doing is griefing minimum-wage employees.
