I'd disagree with you on this one. I think instincts are often wrong, particularly in difficult, intense situations, and that's where training comes in. Experience is part of training, among other things. Training, acquired in a cool, calm, rational state of mind, is what's going to save you when the crap hits the fan. When you're dealing with life-and-death type stuff, you can't rely on learning by experience and instinct. Some things, you just don't get to repeat until you get it right.

Experience means nothing unless you learn properly from it.
So many people practice lapping on track days without ever analyzing what they're doing wrong. They'll do lap after lap, session after session, track day after track day, and have tons of experience running the same wrong lines, upsetting the suspension, etc.
A similar rider with the same aptitude with much less experience but more training will leap frog the rider above, having the benefit of a third party with more knowledge (and good coaching skills) critique their riding and teach them new skills and techniques.
