It is actually worse.
it is known that areas which got access to a formal education (schools), would get quickly much better average IQ score than before.
If just visiting school increases your IQ (some measurements suggest 14 points), then it is clearly not a fundamentale quality.
So even without specifically learning for the test, you can learn for the test.
I don’t see anyone making the claim that it is bad and for all, we know it is op’s swing.
Why are you acting like someone said it is bad? Honestly, it feels like it is projection over your own shame over your preferences. But obviously I don’t know and I don’t claim that it is the case. Just saying, it makes that impression to me.
