For over a year, the Belgian “research group” Data Driven has been sending out remarkable research results to the press that have been frequently picked up by Belgian and Dutch newspapers. Remarkable news snippets like: “the average Flamish Liberal (in the European sense) voter has more sex than other voters”.
Belgian newspaper Het Belang van Limburg however got suspicious and started to investigate the “research group”.
They found the “research group” is in fact the production company Woestijnvis (“desert fish”), who is behind a well known Belgian satyrical TV program, Man Bijt Hond (“Man Bites Dog”). The hoax “research news” according to a spokesman of the production company was intended for a new item in the TV program. He praised Het Belang van Limburg for being the only newspaper critical enough to unmask them.
