I remember watching an anime, around 3 or so years ago, called "psychopass". It was about a dystopian country that was governed by technology.

The system would decide what would be the best position for somebody in the government if they desired to go there. It'd also monitor people and evaluate in real time their psyche. People who were predisposed to psychopathic and/or sociopathic behaviour were flagged and monitored. The police would use guns that tranquilized flagged people and disintegrated people deemed public danger.

This article painted China as a predecessor of the country presented in the anime.

As for the ranking / credit system. I don't believe that such an idea is feasible, as it resembles elo. We know from online games such as League of Legends that elo is not an appropriate metric as it's often governed by multiple variables out of the individual player's control. While in the 'long run' it evens out, it often creates the illusion that a player stuck because of their environment and not themselves, which while may be true in a few cases, in most cases is false.
