At the same time, however, Murray is careful to position his work as _nonthreatening_: "there are no monsters in the closet," he writes, "no dread doors that we must fear opening." He likewise "state[s] explicitly that [he] reject[s] claims that groups of people, be they sexes or races or classes, can be ranked from superior to inferior [or] that differences among groups have any relevance to human worth or dignity." +Murray positions _Human Diversity_ as a corrective to a "blank slate" orthodoxy that refuses to entertain any possibility of biological influences on psychological group differences.
