详细信息----------Details----------
Burt used these and similar data to argue that IQ was largely inherited, a view which strongly influenced British education through the creation of the 11+ exam, which was used to decide which children should be given different forms of education. However after his death it was suggested that the data were fake, a view accepted by some and strongly rebutted by others.
伯特使用过这些和类似的数据认为，智商主要是遗传的，强烈影响了英国教育的11 +考试，这是用来决定哪些孩子应给予不同形式的教育，通过建立一个视图。然而，在他去世后，它的数据是假的，接受的观点，并强烈反驳别人。
