The authors analyze selected contemporary Polish academic publications on psychology in order to demonstrate how the concept of gender is constructed in them. They refer to the premises of Kenneth Gergen’s social constructionism, and Ludwik Fleck’s description of connections in common knowledge. In presenting the bases of constructionist ideas, they concentrate on the process of creating knowledge in the social sciences, its interaction with common knowledge, and the significance of gender categories. They also describe the activities that have been undertaken since the 1980s—on the basis of western psychology—to eliminate negative gender stereotypes from scientific and scholarly works. The nature of the errors and shortcomings that could appear at successive stages of the research process forms a departure point for analyzing examples of stereotypical images of men and women in peer-reviewed empirical works published in Poland after 2000. The summary refers to the Polish regulations in regard to the professional ethics of psychologists and in respect to conducting scientific research.
