This article critiques The Bell Curve's assumptions about ability, bio
logy, and ecology. It argues that the measures of ability assessed on
IR tests are essentially measures of literacy, which is largely a soci
ally constructed outcome, This proposition is validated using data fro
m a large national sample of students and hierarchical regression tech
niques. The cumulative impact of social factors on literacy attainment
was found to exceed that of cognitive abilities. The primacy of the m
ore proximal factors of academic setting and group membership (race/et
hnicity, gender, and geography) plas established over the more remote
factor of socioeconomic background. An alternative paradigm that rejec
ts The Bell Curve's argument for elitism is offered to overdetermine t
he cognitive and emotional growth of all learners.
