All technology impacts human intelligence – what we can know, what we can do, and how these may be linked. Similarly, laws of computation determine or at least limit what is knowable when, regardless of whether we are discussing individuals, societies, or their machines. This course examines the scientific undergirdings of both ethics and policy, as well as how ethics and policy might inform and impact each other, with particular emphasis on communications and inteligence technologies (AI). Topics include the evolution of intelligence, sociality, ingroup-outgroup dynamics, polarisation, cooperative and competitive behaviour, inequality and extremism, historic interpretations of ethics, and impacts of surveillance. Marks are determined by quiz, in-class discussion, and a final exam.
