Document Summary
Intelligence runs in families: family studies show significant correlations and can be very biologically based. It"s very easy for the environment to slow and drag down intelligence, although a genetic relation to iq is a window, the environment is the ultimate determiner as it influences us. Identical twins iq: r = . 70-. 80 (dizygotic; correlation is higher because they share dna): fraternal twins iq: r = . 30-. 50 (monozygotic), cousins iq: r = . 15, heritability of iq is 40-70% and becomes higher in adulthood. The older you get, the more your intelligence is aligned with your parents/your genetics. Identical twins reared apart are as a similar as intelligence tests on identical twins reared together. Iq is nothing like the people who raised you but the people who gave birth to you. Positive eugenics vs negative eugenics: sterilization of thousands and restrictions of immigration from 1920s-1970s. In alberta, the sexual sterilization act led to over 2,800 individuals being sterilized from 1928 to 1972.
