The Flynn Effect, intelligence, and US Black/White IQ
- 👤 Speaker: Professor James Flynn, University of Otago
- 📅 Date & Time: Monday 11 October 2010, 17:00 - 18:00
- 📍 Venue: SPS Seminar Room
Abstract
The Flynn Effect is the increase in raw IQ scores over time. Massive gains in the past century put the mean IQ around 1900 on today’s norms at about 70, the cutting line for mental retardation. Some studies of measurement invariance over time report that the size of gains on WISC subtests do not mimic the magnitude of their g-loadings, which seems to indicate that IQ gains are not general intelligence gains. However, the magnitude of the US Black-White performance gap on the subtests does correlate with g-loadings. These facts pose problems: (1) In what sense are IQ gains intelligence gains? (2) If generational IQ comparisons are “empty”, why are IQ comparisons between individuals and groups significant? (3) If gains over time are “empty”, why be impressed that Black gains are larger than White gains? Professor Flynn will share his latest thinking on these controversial topics.
