“Expert” systems were all the rage in the late 1980s, as demonstrated by a previous Computer Chronicles episode on their use in law enforcement. But expert systems tended to be expensive–costing tens of thousands of dollars–and thus only available to businesses and institutions. Yet by 1986 there were efforts to market lower-end systems to individual consumers. This next Chronicles episode from February 1986 looks at the meeting of the minds, as it were, between expert systems and another mid-1980s boom market: pop psychology and the self-help movement.
