Svrha je rada povezati konstruktivistički pristup javnim politikama s pojmovima znanja, moći i istine kod Michela Foucaulta te iz spomenute poveznice sintetizirati korisne uvide za istraživanje javnih politika. Najprije se razrađuju osobine konstruktivističkog pristupa, daje se osvrt na podjelu na "stroži" i "mekši" konstruktivizam te se nude odgovori na određene kritike konstruktivizma. Potom se podrobno razrađuje pojam istine kod Foucaulta kao i ostali važni pojmovi u Foucaultovu pojmovnom aparatu poput znanja, moći i diskursa, te se naposljetku iznosi poveznica između Foucaultova rada i konstruktivizma. Pitanje koje nadsvođuje rad jest pitanje mogućnosti utvrđivanja objektivne istine u području društvenih znanosti te relevantnosti objektivne istine za javne politike i polje političkoga općenito. The goal of this paper is to bring together the constructivist approach to public policy and Michel Foucault's concepts of knowledge, power, and truth, and to synthetize useful insights for public policy research from that connection. First, the characteristics of the constructivist approach are elaborated, and commentary is provided on the distinction between "rigid" and "soft" constructivism, and the answers to certain criticisms of constructivism are provided. Then, Foucault's concept of truth is elaborated in detail, as well as other important concepts in Foucault's conceptual apparatus such as knowledge, power and discourse. Finally, the connection between Foucault's work and constructivism is presented. The overarching question of the paper is the question of the possibility of establishing objective truth in the area of social sciences, and the relevance of objective truth for public policy and the political field in general.
