Intelligence tests are biased against diverse populations; Section 3. Influences on Intelligence: 11. IQ only reflects a person's socioeconomic status; 12. High heritability for intelligence means that raising IQ is impossible; 13. Genes are not important for determining intelligence; 14. Environmentally driven changes in IQ mean that intelligence is malleable; 15. Social interventions can drastically raise IQ; 16. Brain-training programs can raise IQ; 17.
