I always love when people insist that schools should teach "Critical thinking"
Because they do. What did you learn in English class? What did you learn the days you were brought to the library in middle school to learn about how libraries worked?
If you took AP language and comp, you were given a very thorough education on how to construct a persuasive essay and therefore a pretty good education in how to evaluate a persuasive claim.
I learned this in bumbfuck nowhere that couldn't afford to heat the school.
It's like all the dumbasses who say "School should teach important skills like how to balance a checkbook or how to do your taxes" as if you don't learn addition, subtraction, and basic english literacy as part of your elementary school education.
You did learn those things, you are just expected to be able to read simple instructions and complete very simple tasks. You aren't supposed to need hand holding for filling out your check book and filling in 14 rows with data from another sheet for fucks sake.
The same people who whine about how school didn't teach them anything important sat next to me in precalc and learned how to calculate loans and interest and yet still sign up for absurd stupid car loans. They literally did not pay attention.
In reality, people don't learn those critical thinking skills because they ignore school. Their parents taught them that education is liberal brainwashing and that it shouldn't be trusted. Their experience is that school is useless because that's what parents and media told them so they didn't pay attention and now as adults they blame the schools and more media insists that it is the schools fault.
