Virtual encounter simulations for comparing public expectations about the role of the welfare state

By the end of September 2022, a plebiscite about a new pension law suggested once more that the western Swiss region of the Arc Lémanique (AL) is politically different from the rest of Switzerland. Newspapers argued that this is the result of the proximity to France with the same language as the AL.  This paper tries to find out, how far the political opinions of the AL are away from the rest of Switzerland and how close they are to France. For this purpose, the author presents a new methodology from computational social science: virtual encounter simulations, which he successfully applied in an earlier publication to similar problems. It is based on the idea of using survey data for the construction of random-dyads of persons, who can subsequently be compared with regard to their political attitudes. By averaging the inter-individual differences of dyads of persons belonging to the same group and dyads belonging to different groups it is possible to compare ideological inter-group with intra-group conflicts.      In order to tackle the initial research question, the author analyses the international survey ISSP-V (2016), focussed on the role of government, also with regard to the mentioned old age pensions. Virtual encounter simulations reveal that the AL is ideologically much closer to German speaking Switzerland than originally expected.
