In his archaeological writing, he adopted a critical stance, interrogating the evidence in light of different diffusionist
believed that "race" did not determine behavior, that cultural and biological context between groups discredited any notion of either a "pure race" or a pristine culture.
In the most original part of the study, Kuklick examines the link between diffusionist
anthropology and the origins of modern psychology out of the pioneering fieldwork of the Torres Straits Expedition of 1898.
Only two diffusionists
were prominent in Reed's (1977) volume, George Carter and Donald Lathrap, who proposed Old World influences on prehistoric New World food production.
This difference, rarely stated explicitly, has bedevilled the dialogue between demic diffusionists
and indigenists (vide many papers in Zvelebil 1986).
