Late in his life, the economist John Kenneth Galbraith coined the term ‘innocent fraud’. He used it to describe a lie or a half-truth that, because it suits the needs or views of those in power, is presented as fact. After much repetition, the fiction becomes common wisdom. ‘It is innocent because most who employ it are without conscious guilt,’ Galbraith wrote in 1999. ‘It is fraud because it is quietly in the service of special interest.’ The idea of the computer network as an engine of liberation is an innocent fraud.
