Do IQ Tests Measure Knowledge?


Knowledge and intelligence are not synonymous, yet there is but one flaw in contemporary IQ tests. What? Many of them are like SAT exams. Do IQ tests measure Knowledge?

Do IQ tests measure knowledge
Knowledge or intelligence?
Do IQ tests necessarily need to measure knowledge?
If IQ tests were constructed to measure knowledge, it follows therefore that such tests were not originally designed to measure intelligence and as such, intelligence tests won't make any more sense than just the measurement of our IQ; if IQ tests were constructed to measure intelligence, it probably would.

Consider that a test is being administered to a person less knowledgeable about English language, if the test is really an IQ test, it would mean knowledge test right that instance. Why? The language barrier which is a form of test bias. Such an IQ test is nothing more than dependent IQ test. It depends on linguistic knowledge of the participant for it to be completed or have its items answered.

Consider another case that Mr. A has never experienced mathematics yet it is likely that he is a highly intelligent business tycoon, knows basic arithmetic, hired people who are savvy at economics and mathemitics, and accept experts' advice. Does less knowledge about mathematics renders his intelligence to null? Of course not. So what?

Pratical wisdom of Mr. A to delegate marketing afforts to subordinates is reliably more useful than just maths IQ that might not be utilized.

Thankfully, Raven's progressive matrices has helped to minimize this type of bias in considerable amount. See the detailed beginners' guide to IQ test to have more understanding of IQ test.

Difference between knowledge and intelligence
Knowledge and intelligence are not necessarily synonyms but knowledge and IQ could be synonymous in contemporary times. IQ tests were designed to measure intelligence, at least with that very intent but they usually measure something else. This is because the items in IQ tests were constructed to do so.

What is knowledge?
Knowledge is the amount of informations that people store in their memory. 'I know this, I know that'. 'I know Kate' which means an acquaitance knowledge because I have probably lived with Kate, or being acquainted with Kate in the office. 'I know mathematics' would mean 'I am savvy at math' because I've learnt math and mastered its operations.

While knowledge is much about information, intelligence is much about a person's ability to act purposefully, think rationally, and deal effectively with his/her environment [in which case adapt or relate well with experiences] (Wechsler, 1944).

Looking at Wechsler's definition, intelligence would require wisdom to act purposefully and thinking rationally would require ability to make good judgement, which if course is also wisdom, and a bit of creativity would be needed to adapt to new environment which would inevitably have some new problems meant to be solved. Hey! It is crystal clear that intelligence is more than just IQ and SAT exam.

Overlap: Knowledge and Intelligence
It is also necessary to critically examine the point of overlap or intersection between knowledge and intelligence. While it might be temtung to separate the two, consider the defintion that intelligence is a person's ability to act purposefully, think rationally, and deal effectively with his/her environment [in which case adapt or relate well with experiences] (Wechsler, 1944).

It follows that a person's who would have such ability to 'act purposefully..' had been exposed to nature and of course his environment which he/she perceives immediately with his/her senses, interpreted, categorized (stored approprately) in his/her brain, and of course becomes the perception that gains much familiarity overtime; this perceptual stimuli being tranduced to electrical impulses, relayed to the brain interpreted, categorized and perceived, is in fact, informational.

See an example of IQ test that attempts to measure wisdom through puzzles; though wisdom seems immeasurable.
