Besides Murray and Herrnstein's "Bell Curve" you need to read "the g factor" by Arthur Jensen. By a pretty simple 15-20 minute test on a child [or an adult] one could find that person's IQ at a minimal cost. Thus one DOES NOT NEED school [or any prior] records, what one needs is the legal permission to test. And the IQ follows a person in life much more tenaciously than any Dangan you could design or imagine - in theory, one could buy [or manufacture] forged Dangan documents, but to buy a better intellect is much more problematic, for it is a biometric parameter.
As for "cognitive stratification" [Murray and Herrnstein's term - what you call "castes"] - it is a fact of life, direct corollary of separation of labor. Instead of being objected to, it needs to be embraced, put to use, and promoted wherever possible.

No one is as blind as someone who sees something that is not there. There is no correlation between caste systems and prosperity. Caste systems lead to corruption. The lower classes will always bring down the upper crust through vice.This country needs to part ways with its caste heavy education system.Before we had the present public school system , we had community schools. Children who were exceptionally smart finished school quicker and went to college. The bell curve only proved that people with a certain level of intelligence would become wealthy however the bell curve book failed to account for how corruption destroys opportunities.A society which places a heavy emphasis on caste is by nature corrupt and poor.Which is why so many high IQ people are desperately fighting to get into this country. If caste systems were peachy most of those people would stay in the third world. This country is a success because everyone (not just those people with 145+ IQ's) believes they will be successful.

Who cares?
