Mark...the author's position is that there is independent peer reviewed science to support the view that a fair society need not be an equally-distributed society across all fields of endevour...that what causes society to " look the way it does" across areas of interest and employment may have a biological basis that negates the need for ever-increasing intervention by the state or private entities focused solely and ideologically on equity and equality. 

the author is right I suspect in that what has the ideology-driven frightened about such science is the idea that it may be used by other ideologies to limit free choice....that is not a reason to deny the science or not be open to the science Mark...that's a reason to recognize that society shouldn't erect artificial barriers to individual access based on group preferences or bell curves
