Learned vs. Taught

Were the Nine Dangerous Things taught in school? Or were they simply learned in school?

I don't recall any of my teachers telling me not to think for myself. Apparently the idea that school is a matter of mindless obedience is one of those ideas that is passed from student to student. (Those students who actually try applying this don't succeed … which reinforces their opinion that the system is rigged.)

To take the most obvious example, item 2 (“Learning ends when you leave the classroom.”) is incompatible with the existence of homework.
