“Ladies, gentlemen, dear audience! Welcome - Καλώς ήρθατε, Bienvenidos, Ласкаво просимо - Welcome to a very special kind of flea cabaret! Immerse yourself in the sparkling world of the miniature circus ring - let yourself be dazzled, enchanted and seduced by the feats of these trained parasites!” Based on the flea circus and the conditioning of fleas, Koprow and her team reflect on psychological manipulation. For reality and truth are contested fields. How to control perception and behaviour? And why are some of these attempts at manipulation work so effective? Is society being seduced or are we only too happy to accept simple explanations? In addition to all these highly political questions, Koprow proves with a great sense of humour that the flea circus is entirely an wrongly forgotten genre that should no longer be ignored by high culture.
