He found his British classmates totally ignorant about the outside world and generally uninterested in broadening their intellectual horizons.
Yes,antiintellectualism is rampant all over western world.It is egarded as elitism and no concern for problems of others.Highly unpopular.
Anyway,since IQ of Poles is lightly superior than english IQ,maybe the differences are more in educational system,maybe polish system is more stiff and more relying on data memorization as it is the case in many countries.
For example greek students who fail to enter greek university due to highly competitive exams,study in UK and do very well.There are about 50000 greek students in UK,maybe the biggest foreign student population.
When some of them get back and enter greek university,they get extremely low grades again,have problem passing even easy exams,while in UK they finish on time.
For example to enter greek medical university,you have to memorize word by word 450 pages of biology,300 pages physics,200 pages chemistry and be able to solve problems in physics and chemistry of university level.The stuff which is taught in Greece in high school is taught in England in first-second year of university.English do not expect pupils to know stuff like that.
So in Greece almost every pupil pays for private lessons for 2-3 years in order to pass the competitive exams where only 10% pass to the university faculty they want.In contrast entrance to english universities is much easier.
I think in Poland there are competitive exams too for entrance to university.I do not know if private lessons are so much extended.
