Herrnstein and Charles Murray because, although I disagree with what the authors argue, there are obvious truths present in this book. The authors argue that there are differences in the intelligence levels of ethnic groups, "another taboo is that intelligence levels differ between ethnic groups." This is already well known and widely discussed among psychometricians and other researchers” (Herrnstein & Murray 15). This is not due to a biological reason, but rather because resources and opportunities are not distributed equally among ethnic groups. However, with ideas like eugenics and other biological superiority mentalities came racist policies. People who believe someone is biologically less intelligent will have little motivation to devote resources to that person. In fact, it seems like a waste of time and money to them. No one will ever admit that these ideas persist today, but when we look at the differences in the quality of education given to the rich versus the poor, it becomes obvious. Especially when the demographic of people who hold most of the wealth is white. However, not everything Richard J. Herrnstein and Charles Murray say can be dismissed. In fact, they point out that measures of intelligence are limited: "Measures of intelligence have reliable statistical relationships with important social phenomena, but they are a limited tool for deciding what to think about a given individual" ( Herrnstein and Murray 27). They say it repeatedly, as they try to clarify their research, their data is very outdated and therefore the statistics are skewed. Many people have used books like The Bell Curve, Intelligence and Class Structure in American Life to justify their ideas and
