I'd argue that the bias is a natural consequence of two interacting effects, neither of which necessarily represents a "tinted worldview": a skew in quality distribution and a minimum threshold for information value. It's hard for a product or service to exceed its expected value by more than a fraction or small multiple, while it's easy to cause misery well in excess of a dozen or even a hundred times the expected value. I believe that's more a reflection of it being easier to destroy vs create rather than a reflection of psychology. Combine this distribution with a heuristic to only report deviations from expectation in excess of a minimum threshold and the "average review score" will reliably undershoot the actual quality. That's only a problem if you want to interpret the average review score as an absolute measure of quality, though, and I don't think anyone really does. Most of us are more interested in communicating and informing our decision processes than in passing moral judgement, and if our goal is to optimize communication then we should expect negative reviews to dominate the discussion because they're inherently capable of more meaningful excursions from the mean. I agree with your overall point: it would be fantastically useful to be able to contextualize reviews against reviewer psychology. That way I could ignore both shouting from negative-nellys and forced positivity from those who feel compelled to balance the universe :-) |

In reality, however, it seems that positive reviews tend to dominate. Using Google Maps reviews as my barometer, I hardly ever see any place rated less than 4.5 stars. So, I tend to think to myself "4.5-5 stars: might be good. 4 stars: probably okay. Less than 4: maybe steer clear."
Though, in practice I disregard reviews, take a plunge, and then decide on my own. Often I find myself in conflict with the average majority opinion.
