With Uber I considered a 4 to be "nothing wrong", and reserve 5 for "amazing service above and beyond".

However it seems that drivers who have an average of say "4.2", despite being perfectly fine and giving above and beyond service 1 in 5 times, gets kicked off. This means that 5 is acceptable and there's no way to mark above acceptable.

I'm odd, I don't expect every trip I get to be above average. That's clearly not possible.

I'm the same way. My instinctive reading of a 5 star system maps it onto a bell curve. So if I received exactly the service I expected, with zero complaints, that's obviously a 3 out of 5. 5 stars means two standard deviations above my expectations. It feels to me like a company that gets nothing but 4 and 5 star reviews should be taking issue with their marketing department for setting expectations way too low.

But in an Uber, giving less than a perfect score can get someone fired. So it's 5 stars unless the driver literally spits on me, and then it might be 5 stars and a complaint. Anything lower than a 5 star rating feels unethical, like stiffing a waiter on a tip.

What I can't figure out is how this is of any use to Uber. They have created a "metric" where a large chunk of their customers regard answering honestly as a social faux pas, at best, so what do they think they're measuring?

People know this and the"real" Uber rating scale is a ten point scale between 4 and 5. Same with Amazon product reviews. Anything under 4 doesn't get a look.

I think a simple thumbs up/thumbs down would be just as effective.

That 4.2 thing really disturbed me. Most people driving for Uber aren't doing it because they want to over their alternative to nothing. I couldn't, in good conscience, give out a rating that puts someone's livelihood at risk.

I only gave out one 3 star, but that was because the driver was very bad, though not taxi-driver bad, which is what I would consider 1-star.
