| Is IQ a Metric Unit of Intelligence and … Stupidity? |

“Can human intelligence be measured?”
“Yes, I think so… Different tests could be used to investigate several kinds of abilities (excluding skills) and the subject’s overall ability, call it intelligence, could be determined”.
“If I want to express it in the SI unit, which metric unit could be used to measure these abilities?”
“Actually, you may call intelligence a unitless and autonomous quantity which is not part of any measuring system as it is expressed by Intelligence Quotient or IQ. A test, consisting of a series of questions, is administered to large samples of different age groups (usually children). Then, the average score at each level is determined, the result being the so-called Binet (a French psychologist) scale. The score of an individual is compared with the group average score giving a quotient called IQ.”
“Aha, I think… I think…I understand. Please, can you explain then, what is the meaning of IQ=200 or IQ=10?”
“ Hmm…hmm… let me think how to answer best…”
“Now, I have an idea for a unit of intelligence !"
"Oh, really?”
“An experiment was conducted with a predatory fish, a pike, in a pond. The pond was divided into two parts with a glass barrier between them. On one side of the barrier there was the pike and
on the other, a group of fish, roach. The pike tried to attack the roach, hitting the glass each time. It gave up after, on average, twenty attempts. What about introducing the SI unit 'the pike' which will represent twenty tries? If somebody learns in a lower
number of repetitions, he/she should be regarded as more intelligent.”
“Well, well, that’s interesting idea! However, it seems that this unit would be quite big if applied to human beings".
"This is not a problem. Metric system widely uses prefixes to create smaller or bigger units, even as the main units of measurements, for example "the kilogram" is a base unit of mass, "the decibel" is the main unit of the loudness of a sound..."
What I mean is that we may construct the main unit of intelligence not "the pike" but "the kilopike", "the decipike" or "the millipike".
"Ha, ha, it sounds funny. I must tell my bridge partner: 'Today, your intelligence at the bridge table was equal 1 millipike!'.
Would not it better, however, to utilize 'the pike' as a unit of stupidity? In order to understand something, an individual requires a certain number of repetitions of an activity and, consequently, an individual requiring a higher number of repetitions is less intelligent than one requiring a lower number of repetitions. The problem is to allocate a certain percentage which will indicate lower
intelligence associated with each repetition.”
“Oh, Mr Binet will not help us, then, perhaps we should adress this problem to the intelligent members of MENSA!”

Dr. L.S. Molema, English Dept., UB: “Students speak warmly of him, especially his capacity for making them understand and feel
confident in a subject that they had previously been inadequately prepared for and were therefore scared of. I have just finished editing the proofs of his new book: “S I Units, Conversion and Measurement Skills” in which his teaching style, so popular with his students, is evident.”
