Psychologist Simon McCarthy-Jones unpicks the research into how our minds work and how it’s being used to manipulate us for corporate profit. He investigates what is meant by freedom of thought – a human right frequently invoked, but rarely defined. In the face of radically advanced surveillance and mental manipulation, McCarthy-Jones shows that there are solutions: many of the sources of threats to our minds – psychology, technology and government – can also offer us new ways to protect our freedom of thought. We can structure society to support free thought, finding a way for science and technology, coupled with social and political will and supported by the law, to liberate and enhance our ability to think freely.
