Results of the StuPa election in July 2016

New: The results of the implementation of the The Third Vote the StuPa-election are available!

We are very proud of being able to present the results of the StuPa experiment after many hours and days of analysis.


What was the object of the experiment?

Primarly the experiment should show the irrational voting behaviour of people. For that, the opinion of 10 different questions was collected by introducing a third vote to the prevailing election system with two votes. Every list standing in the election gave its opinion to this 10 questions. (Explanation: At the StuPa election we do not speak of parties, but of so called lists). 
Thus, it can be analysed if the opinion of the voter is consistent to the opinion of the elected list.



First we want to take a look at the result of the election by only paying attention to the second vote. This is the submitted cross for the list (Image 1).

In fact, we could detect irrational voting behaviour at the StuPa elections. Not FiPS, but Juso is the most representative list measuring only the consistency of the voters´opinions. We introduced the variables Popularity and Universality to measure the real consistency of voters with the elected list. In the following they are shortly explained: 

  • Popularity: Popularity expresses the part of the voters, that have the same opinion as the analysed list, averaged over all 10 questions. It is the average percentage of the population represented. 
    • Example: The Juso list reaches a pupularity of 50 %.
      The Juso list rejects question 1. 31 % of the voters reject question 1, too. 
      The Juso list rejects question 2. 49 % of the voters reject question 2, too. All these percentages are added and divided by the number of questions.
      At the end we obtain the part of the voters that have the same opinion as the Juso list. 


  • Universality: Universality is the percentage of the questions, in which the opinion of the list is the same as of the majority of voters.
    • Example: The LHG reaches a Universality of 70 %. The LHG represents in 7 of 10 questions the opinion of the majority of voters - i. e. 70 %.
      Important: Here only the consistency with the opinion of the majority to each question matters.


We analysed also the difference between the voting behaviour of voters who used the voting advice application StuPa-O-Mat before the election (s) and of the ones who did not do so (o).
According to the analysis students who did not use the StuPa-O-Mat vote more irrationally than students who used it before. In the image 2 the results can be observed.


Results of the Third Vote Experiment

Image 2: The Indices of Popularity (P) and Universality (U) of the prevailing list are shown for all voters (a). Besides, StuPa-O-Mat users (s) and Non-StuPa-O-Mat-users (o) are distiguished from each other and listed also in the diagram. The Mean Index represents the average of the Popularity and Universality.
