RE: New Milestones: 4k Account Tokens and 80 rep.

I see your point, not so sure about the bell curve here though. There is an assumption that the median average experience is equal to arithmetic average experience, which doesn't seem to be rooted in reality. The quality of service is constantly upgraded, hance prevalance of 5 star reviews, if everything is ok, there is no need to lower the score. There is a gratitude.

Owners and service providers and incentivised to provide nice experience. And on the other side of spectrum there are people.whose expectations were not met. And this is a situation when some people decide to leave a review, and only then. Does it make these groups of people full of shit? Even if they might be the same people sometimes?

The game theory here seems to be much more complex than influence of emotions on the system. Sure, some people are terrible at giving feedback, and sometimes, we all have this bad day, when one small detail can make a difference. It seems to be more than simple algorithm.
