The paper highlights the often not reflected weaknesses of diagnostic tools used in the study of masculinity and feminity. Attention is paid mainly to structural limitations of the tool most widely used for this purpose - Bem Sex Role Inventory.
Its use is based on theoretical assumptions that have never been successfully empirically verified. Although criticism of Bem Sex Role Inventory has been formulated more than 30 years ago, this technique is still used in a number of recent studies.
In the second part alternative measurement techniques are presented. These are based on discriminant analysis and the implicit association test.
