No way... that's the most retarded thing I've heard for a while now, and I did read about international news.

Introspection is basically THE core mechanism for learning. That's HOW one learns on any topic. It's not a "wishy washy hippie feeling" (being provocative here) but rather introspection is (and to be fair I verified with https://plato.stanford.edu/entries/introspection/ just to make sure I wasn't talking out of my own ass) precisely looking at your inner workings. How you function IN ORDER to do better. You notice flaws, inefficient behaviors, things you enjoy, etc THEN you act on it.

Having no introspection is like doing math without verifying. It's like coding without compiling, linting or even executing without looking at the output.

So dumb it hurts.
