Lieberman was a prominent critic of the racial theories of J. Philippe Rushton. One such example is a journal article where Lieberman traced the origins of Rushton's theories showing that Rushton used secondary sources to obtain the size of skulls upon which he based his research about the cranial volume differences of racial groups.^[4]
