Document Summary

Has many issues in terms of definition (ex. street smart vs school smart, understanding different things better vs worse) Iq: determined from validated assessment battery (wais-r), narrow definition of intelligence. Iq changes over time, but around age 7-10 it becomes a good predictor. Intelligence measure is culture-defined (measured according to the general definition of (cid:862)s(cid:373)art(cid:863)(cid:895), ge(cid:374)erall(cid:455) refers to i(cid:374) ter(cid:373)s of a(cid:272)ade(cid:373)i(cid:272)s/(cid:448)er(cid:271)al i(cid:374)tellige(cid:374)(cid:272)e: common definition: ability to plan, reason, solve problems, think abstractly, comprehend complex ideas, learn quickly/from experience. Iq tests are used in other western cultures with european roots, but they do not translate well to the language and other cognitive frameworks of non-eastern countries. Genetics accounts for 50-70% of variance in iq points (in a population, not that 50-70% is directly from genetics) Flynn effect: iq has slowly increased over the generations. Larger brain may indicate greater intelligence (average correlation between 0. 35-0. 40), and higher iqs indicate a lower mortality rate earlier on.
