That would be an amazing class. Even dropping the "offensiveness" billing and just advertising it as a class that would expose you to as many new and unconventional ideas as possible would be pretty neat.

While we're asking for the impossible, I'd kind of like to scrap the entire current primary/secondary school curriculum and replace it entirely with rationality. You'd learn math on the way to being able to use Bayes' Theorem. You'd learn English while writing counter-attitudinal essays. You'd learn history because your assignment is to point out what cognitive biases led Napoleon to make the mistake of invading Russia, and how you would have done better in his shoes. And then you'll play a game of Diplomacy (or Civilization IV, or whatever) to prove it. All exams are calibration tests.

People will complain that it might not give people the same breadth of knowledge. But our current curriculum is entirely about signaling breadth of knowledge. I learned about Sargon of Akkad in sixth grade and I have >90% confidence I'm the only person in the class who remembers his name, and that entirely because I'm the sort of person who would read about people like Sargon anyway outside of class. Once the primary/secondary school system is producing a generation of scholars of Mesopotamian history - or even people who can still speak Spanish five years after their high school Spanish class is over - then they can complain about breadth of knowledge.

But if you optimized the entire school experience for learning how to evaluate information and make good choices, maybe some of that would stick.
