This note presents an outline of the social and intellectual conditions accounting for the rise of “conspiracy entrepreneurs”, that is these heterodox thinkers who make a living from their denunciations and revelations on the malevolent organisations and characters who really lead the universe. A special attention has been focused on the reports concerning conspiracy entrepreneurs in the media, which describe them as eccentric and thus entertaining. After the presentation of some studies of David Icke's reptilian hypothesis, a question is raised: is it not legitimate to assert that academics studying conspiracy theories are themselves conspiracy entrepreneurs through their role in the spread of the subject of their studies.
