Psychologist Linda Gottfredson criticises the unempirical nature of triarchic theory. Further, she argues it is absurd to assert that traditional intelligence tests are not measuring practical intelligence, given that they show a moderate correlation with income, especially at middle age when individuals have had a chance to reach their maximum career potential, and an even higher correlation with occupational prestige, and that IQ tests predict the ability to stay out of jail and stay alive (all of which qualifies as practical intelligence or " street smarts ").   Gottfredson claims that what Sternberg calls practical intelligence is not a broad aspect of cognition at all but simply a specific set of skills people learn to cope with a specific environment (task specific knowledge).

illness is not so far from health, if personality can be changed later
in life, if culture and genetics aren't too powerful, and if our
can at least be made conscious, we have more grounds for optimism. The
theorists we will look at were at least optimistic enough to make the
at understanding human nature.
