Distilled down to its barest essence, intelligence can best be described with this inordinately simple algorithm: Smart people think before they speak, while stupid people speak before they think. That’s it! That’s all there is to it! That, Reader, is the true, unabridged definition of intelligence. The highly conceptualized and theorized idea of intelligence contentiously debated by multi-degreed psychologists and neurologists is really no more complicated than this shockingly elementary truism. Smart people seldom, if ever, get themselves into trouble with their mouths, while stupid people unfailingly do; they just can’t seem to help themselves! Diarrhea of the vocal cords is the canary-in-the-coalmine predictor and single hallmark which unfailingly defines a dearth of basic intelligence.
