In 1995 at the University of California, Santa Barbara, the usual psychologists, anthropologists, and other academics showed up for the annual meeting of the Human Behavior and Evolution Society. Science journalist John Horgan was also there. He heard various presentations, talked to various members and found that "the most influential thinker there, arguably, was a scruffily bearded fellow, wearing sunglasses and a knitted cap, who never gave a talk. He lurked around the margins of the conference." Horgan "spotted him puffing a joint outside a meeting hall."
