I think you may not realize just how intellectually-challenged someone with an IQ of 80 is.
In any case, let's put it this way: given two potential lawyers, equal in all other ways -- people skills, years in practice, etc ... -- whose only difference was one had an IQ of 130, and the other, an IQ of 80 (which is completely unrealistic since they couldn't pass the bar exam... 80 is just a few points above moron level) ... in those circumstances you would be just as happy with the IQ 80 guy as with the IQ 130 guy? Seriously?
