title: Complexity of IQ: comment on Ceci and Liker (1986).
abstract: Ceci and Liker (1986) reported statistical independence of IQ and cognitive complexity as evidenced by horse-race handicapping. However, they dismissed too easily a potentially important finding contrary to their hypothesis: a negative correlation between IQ and years of horse-race experience among horse-race experts. Furthermore, F values for the relation between level of handicapping expertise and either level of education or occupational prestige (each of which correlates highly with IQ) are statistically too small and therefore suggest selectional biases.
