On their manifesto Mannerismo Critico Robert Haussmann describes Mannerism as a "scrutinising of familiar and thus habitual, thinking and behaviour patterns", it "turns against established ideas of order and value, against rigidity of any kind". He also uses words such as liberation, humour, irony and self-irony.
