“Douze points!” A research paper on reducing the effect of the familiarity factors by type of voting system

Many studies have been done about the Eurovision Song Contest. This study has investigated which external factors have an effect on the difference between the number of points a particular voting country assigns and the quality of the song. The paper also tries to find whether changing the voting system reduces the influence of these external factors on that difference. After analyzing voting data from 1975-2018 it appeared that there are several external factors that affect the voting bias. This paper revealed a significant effect that changing the voting system reduces the influence of most of those external factors. The voting system where a jury of experts is been used, reduces the effect of most of the external factors on the difference.
