There's an interesting bit in "surely you're joking, mr Feynmann" where he is amazed how primary school kids are learning physics. Only, as it turns out, nearly noone in the entire country has any actual understanding of physics, because from elementary school upwards all they do is memorize the material.
They could remember the exact type signature of standard library functions.
They could define a Monad instance from memory at the speed they could type.
But you couldn't ask them a single question outside of what was presented at lectures.
They couldn't solve a single assignment. They were stuck on rote learning.
I'd blame their educational system, because it was quite consistent (sample size = 3).
The classical example: Teacher says X, the whole class repeats in choir X.
