If one is perfectly rational (omniscience would even be better), yes, otherwise I do not think it is a good idea for a lot of reasons. Just on the top of my head :
It is very hard to be accurate, let alone objective, when analysing “impact on society” or “quality of character”, and the result is dependent on the criteria used.
When there is a big variability within a group (race, genre or whatever), statistics are not very useful and you should end up with a better model by getting to know the person.
Anchoring effect : People are bad at updating evidence when given a first information, there are already enough problems with stereotypes without making it official.
Given a set of parameters, there would be strong incentives to neglect others parameters or to game the system.
Personal responsibility : One qualities depends on a lot things, what are we taking into account? Nature? Nurture? Nothing?
I am somewhat new to LW, so I only know the “eternal september” period.
Even tough the contributions and the comments do not have the same quality as the old content, there are still (in my opinion) some interesting posts and discussions, so I’d prefer not archive LW.
The use of LW as focal point would really interest me since I am a bit lost in the diaspora, the other two points are also good and deserve to be implemented.
