IQ is the single best measure of job performance actually. As for its ‘impossibility’ - That’s another load of nonsense. First of all, an intelligence test cannot and is not designed to tell you the reasons people score differently. So the fact that the test by itself has nothing to say about genetics is not a failure of the test.
Second, the assertion that cultural marxists make of widespread chaos within science over intelligence is false. The statement that there are a number of theoretical differences about the concept of intelligence is only trivially true. In the practical context of research, provisional understanding, and ‘normal science’ this is rhetorically equivalent to underlining evolution as “only a theory” in media reports.
Intelligence as a working scientific research concept and tool is both widespread (as a search for terms such as ‘IQ’, ‘Intelligence’ or ‘cognitive ability’ on PubMed, Google Scholar, or similar publication databases will show), and broadly consistent in approaches and shared theory, methods, premises, and data. The American Psychological Association’s 11 member ‘taskforce’, assembled for a consensus statement on intelligence research, reported:
[M]uch of our discussion is devoted to the dominant psychometric approach, which has not only inspired the most research and attracted the most attention (up to this time) but is by far the most widely used in practical settings.
Blatant fucking falsehead. Either you’re willfully ignorant or just plain stupid, I’ve cited many studies in this thread showing its predictive qualities, and those several studies are but a fraction of the evidence available.
No it doesn’t. You missed the point about any test, even vaguely cognitive ones, having a positive manifold.
Anecdotal evidence. Probably made up ex nihilo too.
On the contrary, the leftist establishment doesn’t like IQ for the same reasons you probably don’t like it - As it doesn’t tally with racial egalitarianism.
Oh, and by the way, many private companies require cognitive tests as part of their application procedure.
