Rubin, Hannah, and Cailin O’Connor (2018. “Discrimination and Collaboration in Science.” Philosophy of Science 85 (3): 380–402) introduced a game-theoretic model to examine the dynamics of collaboration and discrimination in academia. They found that small minority groups face higher rates of discrimination in collaboration, despite moral and legal demands for equality. This paper extends their work by assessing the effectiveness of anti-discrimination measures, focusing on German legal provisions for discrimination in the workplace: internal complaints boards and training and organisational measures (...) as mandated by the General Equal Treatment Act. My results show that internal boards are effective in preventing discrimination in initially fair (i.e. non-discriminatory) environments, but fall short in already discriminatory environments. In contrast, training and organisational measures significantly reduce discriminatory behaviour, even where awareness is low. This highlights the importance of proactive anti-discrimination measures.
