Proposals for the democratization of technology imply a necessary condition of universal emancipatory technological literacy. However, in the literature on the topic, people’s willingness to assume the cost in time and effort involved in acquiring that knowledge is often taken for granted. In this paper, we apply Anthony Downs’s economic theory of political action in democracy to analyze the cost-benefit ratio of this literacy from the perspective of the individual subject who should acquire it. Our conclusion is that the cost (...) does not rationally justify in an instrumental sense a benefit that, being mainly of an indivisible nature, motivates individuals to avoid their share of the cost to produce it.
