The Bad News Game is a multiple award-winning fake news intervention aimed at building psychological resistance against online misinformation. The intervention is a theory-driven social impact game developed in collaboration with the Dutch media collective DROG and graphic design agency Gusmanson.


The game is freely available for non-commercial use and can be accessed here:

The game draws on the theory of psychological inoculation: just as exposure to a weakened strain of a pathogen triggers the production of antibodies to cultivate immunity against a virus, the same can reasonably be achieved with information. Specifically, the game forewarns and exposes players to severely weakened doses of the stategies that are used in the production of fake news to stimulate the production 'mental antibodies' against misinformation.
