The book examined humanity's long relationship with technology across archaeological and historical time, arguing that the inability to foresee the consequences of technological creation was not a failure of intelligence but a consequence of the cognitive architecture his career had mapped — the architecture that processes threatening implications through filters designed to minimize their psychological impact. The book received mixed reviews from Festinger's social psychology peers, who expected the methodological rigor of his experimental work.
