This questionnaire was developed based on Nolan’s diagram. It has two axes: horizontal one with right-left axis, focusing on socio-economic issues and vertical one with conservative-liberal axis, which is focused on cultural and value systems.
As with all questionnaires, the accuracy of the results is largely dependent on the sincerity and the level of knowledge of the person completing the questionnaire. It should be noted that it is impossible to determine the respondent's political ideology (for example, social-liberal, green, Christian-democratic, social-democratic, etc.) with complete accuracy through just one questionnaire.
To resolve that issue another methodology is needed, particularly in-depth research by qualitative methods.
