A recent paper defined a CQ that was used in mathematical calculations instead of the traditional IQ. The difference between CQ and IQ is almost the same as between the strength, of an arm muscle measured by arm wrestling for instance, compared to the physical value of force as it is defined by Newtons’s law. Force is what accelerates a certain mass according to the formula given below.
Intelligence is a subjective property describing a man’s intellectual capabilities, as strength describes his physical capabilities. (Please excuse sexual language that may annoy somebody. This holds true for women too, of course.) As strength can be measured by various methods with slightly different but statistically correlating results, also intelligence can be measured by different IQ-Tests, and again they produce different results, but on average they correlate.
Newton didn’t bother to develop his classical mechanics on such a shaky ground as strength measurements, and all the same, if you are trying to perform model calculations on intellectual capabilities, you cannot rely on a paramater that is both subjective and test dependent. Therefore a CQ, capability quotient, has been introduced. The CQ is task related. The better the outcome the better the CQ. In a special case, if the task is a specific IQ test, CQ is identical to IQ.
