Footage of Richard Dawkins propounding his gene-centered view of evolution is shown, with archive clips spanning two decades to emphasise how the severely reductionist ideas of programmed behaviour have slowly been absorbed by mainstream culture. (Later, however, the documentary gives evidence that cells are able to selectively replicate parts of DNA dependent on current needs. According to Curtis, such evidence detracts from the simplified economic models of human beings.) This brings Curtis back to the economic models of Hayek and the game theories of the Cold War. Curtis explains how, with the "robotic" description of mankind apparently validated by geneticists, the game theory systems gained even more currency with society's engineers.
