This is interesting to me though. Didn’t most people (at least in developed countries) take tests in school? Get grades? I would think if you did below average on those you kind of…should know that you’re in the bottom half?
I get that it’s possible to make changes after schooling, and grades are only somewhat reliable (in that they also rely on effort) but still.
See I don’t buy into this. To me, this is getting into seriously conspiracy theory stuff. I don’t think that there is some grand plan to keep people stupid so that they don’t cause trouble.
I think the system just fails at educating students well due to a variety of factors.
