In the paper we open the question of the correlation of scientific researchers and the ethical credibility of this engagement. The purpose of this paper is to point out to the significance of the connection between the scientific, especially social researches and the ethical postulates which we use to regulate the way in which they operate. The author refers to cases from the research practice pointing out to the presence of antagonism between the scientific ambitions and the ethical principles as well as to the necessity of its overcoming through harmonization of the scientific interest with the interest of the individual and the community. In the paper we conclude that only the research, which is conducted in accordance with "the ethic of concern" and with the respect of the ethical regulation procedure, can preserve the academic integrity of the researcher and make possible reliable research results.
