In most cases, people who are masters at something tend to be the worst teachers because by becoming the master they have forgotten how to sympathize with complete newbies.

It is possible to teach someone Lisp, or something like it, without teaching them all of it at once... if ever. There are lots of people who use CAD systems like AutoCAD, or Emacs, or the various Lisp based/inspired Expert Systems shells, etc. who wouldn't consider themselves 'Lisp programmers' who learned just what they needed to be productive. If people were exposed to it a bit at a time, rather than the fire hose with minimal direction, I suspect a lot of complaints could be addressed. For example, the reason people think all the parens are bad is because it's become a meme and it's different than what they're used to. If they had started with Lisp and never learned ALGOL-inspired syntax, semicolons would likely look very strange to them.
Of course this process could be done in an advanced language that grows with the user, but most modern languages are not that - even Python expects the user to understand at least the rudiments of structured flow and objects almost immediately. Lisp (Common or Scheme) isn't it, either - lambda calculus is already far too abstracted from the "series of instructions" model which is a critical foundation for computing in the real world. C, my next step after BASIC, has quite a good balance of available abstraction and a tractable mental model; but the amount of boilerplate (the requirement for main() always seemed baroque to me) and hand holding of the computer (total lack of even trivial type inference) is not ideal for a beginner language.
See "Not in our Genes" by Lewontin, Rose, Kamin, for a thorough discussion.
In practice, it is a result based on twin studies, but with very low standards: for one thing not double-blind, definitions were let swing arbitrarily by the interviewers, and so on.
Definitions of intelligence are themselves questionable, techniques to measure it, even more so. The history of IQ has been tainted by plain fraud... And the whole field is too a succulent target for ideological warfare... truth is too easily a collateral casualty. This should not be considered science.
