INTELLIGENCErace and ethnicity

In this presentation…

• How do we define intelligence?• Adaptation• Studies in Intelligence, Race and Genetics• The Flynn effect

What is intelligence?

• Thinking • Adaptation• Learning from everyday experiences• g factor, IQ, etc.

Adaptation

o Sternberg, Grigorenko, and Kiddo Common Ancestoro Adaptation o Race as a Social Construction

Intelligence, Race and Genetics

• Many attempts have been made to establish a connection between Intelligence, Race, and Genetics.

Intelligence, Race and Genetics

• Although there are many differences between races there has been no connection between race and intelligence identified.

Intelligence, Race and Genetics

• Whatever positive findings have emerged have either failed to replicate or produce a weak signal that have not yet been attempted to be replicated with independent samples.

The Flynn Effect

• Rise of average IQ • James R. Flynn• Convergence of Black and White• Environment and IQ

1960s

o Schools closed for black childreno Poor IQ performanceo IQ factors--nutrition, families, education,

environmental complexity, familiarity with the test

Recent studies

• 2003, Kenyaparents' literacy, family structure, children's

nutrition and health• 2006, Brazilcognitive stimulation, nutritional hypotheses

Conclusion

• IQ and g factor are incomplete in defining intelligence

• Even IQ tests don’t show much difference in races

• Race is a social construction, not a biological construct
