Where in the world do people need education on critical thought? How do you even educate for that? I've always thought of critical thought as a natural instinct with close ties to curiosity and survival.

In college I've had a discipline¹ in critical thinking (I studied Software Engineering in Portugal). We analyzed arguments in texts presented by the teacher and written by each other. It was mostly learning by doing, and seeing others doing.
¹Is this the right word? I'm struggling to find the right translation.
Sure, and I could program too, but the course was still useful. Critical thinking is a skill, and I think there's value in training it in a methodical way and with some guidance.
