I see a lot of 3s and 4s, which according to the key means "High Potential to Be Among the Best in the World" and "Currently Among the Best in the World". Maybe I'm just ignorant or jealous, but I have a hard time believing that all those young people could already be called "among the best in the world" in any field, at least not without serious evidence to back that up.
But I think the problem is mostly that the scale from 1 to 4 makes it seem that 2 or 3 is the average, which it's obviously not judging from the description. I think that causes people to greatly inflate the ratings. Also the aim seems to reach 10 which must skew the distribution upwards some more.
Is this type of ranking new or is it just the first time I encounter it? I ask because there is an other story mentioning "10x" in the frontpage right now, I don't know if the two are related however.
