An awful lot of people think that the various academic degrees they have obtained are somehow proof of intelligence.
But to have been brainwashed at some prestigious university is an indication of priorities, not brainpower.
You can usually get a pretty strong sense of someone's wattage simply from chatting with him for five minutes. How much common sense does he have? How quick is he? How witty? Is he receptive to cues? How resistant to new evidence is he? How well reasoned are his arguments? How willing is he to stray from commonly accepted wisdom? To what extent can he think for himself?
The only thing a PhD's confirms is that someone has been content to devote a big portion of his life to academia.
Just as truly tough people don't care about whether or not they're tough (they just are), truly smart people tend not to care about degrees.
It's oversheltered mama's boys -- like me -- who place the greatest premium on being tough. And that's for good reason: because we're not.
Likewise, it's those of average intelligence who place the greatest premium on academic degrees.
Bobby Fischer -- generally acknowledged to be one of the two greatest chess players of all time -- was a high school dropout. But his brain was a Cray XK7 Supercomputer compared to the abacus most PhD's have to work with.
The presence -- or absence -- of a degree does not change biology.
A person with a high IQ can be (depending on his temperament) a joy to be around. He at least has the potential to delight you with his wit, or insights, and maybe he can even help you solve your personal problems.
On the other hand, anybody who brandishes his degree like a weapon is a chore. Unless you enjoy pedantry, pretentiousness, and a wealth of received opinions.
In a sane world, people would boast about their IQ's, not their degrees.
