Murphy et al. (2022) raised concerns regarding the validity of the Four-Item Mentalising Index (FIMI). We wholeheartedly agree with Murphy et al. that there are problems in the social cognition literature hampering research. However, we maintain the FIMI is conceptually grounded in empirical and theoretical research, and that concerns regarding its construct validity are overstated. Drawing on recent research, we also discuss issues concerning the interpretation of discriminant validity analyses and discuss approaches to improve objectivity in future research. Overall, we argue that the FIMI is a conceptually and psychometrically sound measure, which has utility in future social cognition research and clinical practice.
