The objective of this text is to present a reflection on the use of the policy of ethnic-racial quotas and the analysis of the use of the heteroidentification technique in Brazil. The theoretical framework is based on the perspective of self technology and its implications in self-declaration in a process of individual recognition by race/colour Black(a) Prieto(a) or Brown(a). The qualitative methodology combines, on the one hand, the method of sociological hermeneutic interpretation in the revision of the normative and institutional model of the ethnic-racial from the institutional-legal system, political systemcollective and individual voluntary submission system, and the other hand, with the method of autoethnography that is designed from stages of analysis of the phenomenon and the dialectic of the process of self-declaration, applying the narrative writing tool of the researched and the researcher; to do this, we analyze a case study based on the self-proclaimed experience of participating in a public service career in Brazil this year. In the results and discussions, from the case explored, dialectical forms have been identified that pass through the subjectivity of recognizing the other as black(a) subject (a) prieto(a) or brown(a) and, at the same time, expressed and felt in first person to have to be subjected and accept it as something of self-consciousness, that implies a provoking feeling of personal conflicts when the response, positive or negative, will depend on what the Committee of Synodal in the examination of merit designated to each new process of offering ethnic-racial quotas in Brazil.
