Lessons from the Bell Curve
重新分析《钟形曲线》一书的核心论点，发现单一智力因素g不能解释测试分数和社会表现，其他可操控因素同样重要，反驳了社会政策无效的结论。
This paper examines the argument presented in The Bell Curve. A central argument is that one factor--g--accounts for correlation across test scores and performance in society. Another central argument is that g cannot be manipulated. These arguments are combined to claim that social policies designed to improve social performance cannot be effective. A reanalysis of the evidence contradicts this story. The factors that explain wages receive different weights than the factors that explain test scores. More than g is required to explain either. Other factors besides g contribute to social performance and they can be manipulated. Copyright 1995 by University of Chicago Press.
