Yet, in this era, those members of our society who master the tools of abstraction can leverage their advantage to acquire unprecedented levels of wealth. They also come in pretty handy for those of us who derive deep satisfaction from scientific exploration and artistic expression. It is almost impossible not to be angry when we hear about incorrect decisions that result from misleading iq scores.

Scientific american is part of springer nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at /us). Scientific american maintains a strict policy of editorial independence in reporting developments in science to our readers. Most events in history are immediately forgotten, even by historians. Those that are repeated and remembered over centuries tend to contain something of central importance to the culture. For example, the phrase “pyrrhic victory” may not be widely known or used but it has survived among educated readers because it uses an episode of history to express wisdom in an evocative and pithy way. Certain key episodes from history serve as templates for our decision-makers (e.G., napolean’s invasion of russia, neville chamberlain’s appeasement of hitler, the vietnam war as a “quagmire.”).

If we think of iq as an estimate of pure potential, including acquired knowledge tests in iq is a very bad idea. We have pretty good tests that estimate various kinds of raw cognitive power (e.G., working memory tests and processing speed tests). We have reasonably good tests of reasoning ability that do not require specific content knowledge.

Due to the large number of subtests and questions in many iq tests, these tests can sometimes take a while and breaks are given to break up the testing day. Letter-number sequencing- the test taker is read aloud sequences of numbers and letters and will recall the letters in alphabetical order, and recall numbers in ascending order. This is to measure mental manipulation, sequential processing, concentration, attention, short-term auditory memory, and memory span. Information- the test taker is asked to answer questions drawn from a wide range of general topics.

Iq tests did not begin as operational definitions of theories that happened to correlate with important outcomes. The reason that iq tests correlate with so many important outcomes is that they have undergone a long process akin to natural selection. The fastest way to disabuse oneself of the belief that binet invented the first intelligence test is to read the works of binet himself—he even shows you the test items he copied from scholars who came before him! With each new test and each test revision, good test items are retained and bad test items are dropped. Good test items have high correlations with important outcomes in every population for which the test is intended to be used. Some test items must be discarded because they have substantially different correlations with outcomes across demographic subgroups, causing the tests to be biased in favor of some groups at the expense of other groups.
