Thats a ridiculous statement and non logical at all. There are so
many barriers to gaining a pilots license ( as you would know) that it

private ones) must be skewed towards higher education , intelligence,
income and determination than the population as a whole ( ie your
average person).

That's wishful thinking. While there is surely some bias in favor of higher
intelligence, it's overly optimistic to assume that this bias is significant,
even in airline pilots.

Anyone can learn to fly an aircraft by rote.
