I agree that investigating things for yourself, even if the answer is well known, is a good thing. I happened to go to a college (many years ago) where everyone (irrespective of chosen speciality) took the same 2 years of math, physics, chemistry, mechanics, numerical analysis, programming etc. Initially I was a bit annoyed by this wanting to jump into computers/EE. But during a physics lab where I was recreating the early bubble chamber experiments to show that charge was quantized I noticed that despite knowing the outcome, doing it myself changed (if only slightly) how I held that knowledge. The same thing can be said for just learning to recognize actual scientific work (understating peer review etc) as opposed to just popular press nonsense.
Sadly I see little to none of FE media (this site included) endorsing that view and instead basically being propaganda.
