How refreshing it would be if everyone was utterly sincere to each other.
It leads to dysfunctional behaviors because people don't want to earnestly told that their face is ugly when they first meet someone and every time after that.
Honesty can be brutal.
This also leads to another issue: when the data is centralized like this, those who oversee it can never be held to the level of accountability they hold others to.
This says more about society than honesty. If we collectively quit valuing physical beauty (you know -- something you're born with and can't control), that kind of statement wouldn't be an issue. Say "I'm bad at basketball" and no one cares. Say "I'm unintelligent" and everyone does.
