“Surveys by Rozelle's team have found that more than half of eighth graders in poor rural areas in China have IQs below 90, leaving them struggling to keep up with the fast-paced official curriculum. A third or more of rural kids, he says, don't complete junior high. Factoring in the 15% or so of urban kids who fall at the low end of IQ scores, Rozelle makes a stunning forecast: About 400 million future working-age Chinese, he says, "are in danger of becoming cognitively handicapped."”
Rozelle的团队发现在中国贫困农村地区，超过一半初二年级的学生智商低于90，使得他们很难跟得上快节奏的官方课纲，他说，三分之一强的农村小孩没有完成初中学业......Rozelle给出了惊人的预测：未来在中国，将有4亿处于工作年龄的人有认知残障的危险。
专家分析造成这个现象的原因之一是因农村儿童父母去城市谋生，留守儿童缺乏父母照看而导致智力的发展受到延误。另一些原因还包括营养不良导致的大脑发育迟缓。Rozelle表示，很多人都不知道，这将是未来中国面临的最大的问题，没有之一。
