Without thinking too deeply about the incentives and unintended consequences, it seems a better rating system would be "thumbs up" and "thumbs down", with the latter requiring some rationale (the text can be checked with AI to make sure it isn't just gibberish).
it would be even better if they stopped proactively pushing a rating prompt and defaulted to 'no rating' which means 'everything is fine'. provide the thumbs up/down in the app that people can use for the situations where it was noteworthy enough to go out of your way to register a vote.
and it might be better to drop the thumbs-up option as well. the rating ecosystems have evolved to a point where the stars aren't a bipolar rating scale from bad->acceptable->great but rather a unipolar scale from bad->acceptable. there's a good chance that the same would happen with thumbs up/down, so why not just jump to the inveitable endpoint of "ratings are only used to report adverse events"?
Back when Foursquare was more popular, I always felt their ratings were much more accurate than Yelp’s. They use(d?) a ternary neutral/thumbs up/thumbs down.
Not sure of their algorithm to generate a score of 1-10 – it’s possible it used more information than just the ternary rating — but their ratings could vary dramatically from sites like Yelp that used the usual 1-5 stars, and seemed to track much more closely to the actual quality of restaurants.
One of Uber's competitors have a 5 star system where 4 and 5 stars show you a few options below with the title "What did you like?". Those are optional. for 3 and 2 they will show "What was the issue?" and you have to write a shot message describing the issue. And for 1 they show no options but will call you and ask what was so terrible about your ride.
I agree with this, although I wouldn't bother with the rationale. It's either you had an overall good experience or an overall bad experience. I'd add a third option called "favorite" or "star" which you could you only give out to 10 drivers/restaurants/places at a time to highlight really exceptional experiences.
