Educated people are the way they are due to a particular personality that they have. They are curious and self driven. Many educated people have no formal education. You cannot teach a personality.

That's not to say other personalities are less worthwhile... It's just that we have emphasized one kind of personality as the ultimate one and then are surprised that -- after maxing out opportunities for those already suited towards that personality -- a saturation point is reached and future effort has marginal gains.

What's wonderful about comprehensive universities is that there's a program that can excite the interest of almost every personality.

And even if that wasn't the case, education in general actually speaks to a variety of personalities: The self-motivated learner, the self-improver, the intellectual explorer, the goal-oriented achiever, the rules-based structure seeker.
