此外，威尔逊写道，参与项目的成年人“此前一生均过着极为底层的生活，无论到新社区里住了多久，早年所受的影响也不能完全消除。”

Robert Sampson, a professor of sociology at Harvard, argued in a 2008 essay published in the American Journal of Sociology that the project should have been called “Moving to Inequality.”

在《美国社会学期刊》(American Journal of Sociology)2008年发表的一篇论文中，哈佛社会学教授罗伯特·桑普森(Robert Sampson)提出，MTO项目还不如叫做“搬向不平等”。

Sampson pointed out in an email that many of the adults in the program had lived in extreme poverty for decades and that the children, who were on average 11 years old when they entered the program, had spent their early years living in adversity. “The result,” he wrote, “is that developmental effects are difficult if not impossible to study in the research design,” which does not reveal the “lagged effects of severe disadvantage.”

桑普森在写给时报的电子邮件中指出，参与MTO项目的许多成年人本已在极端贫困中浸淫了几十年，而他们的子女在项目开始的时候平均年龄为11岁，也已经历了早年的逆境。“结果，”他写道。“在这样的实验设计之下，很难、甚至是不可能研究发展效应，”因为这种设计没有揭示出“严重贫困的滞后效应”。
