Presenter Artsiom Klunin Abstract There is currently no consensus among scholars on the stage at which partisan bias occurs: during the perception of information, during its processing or at presentation. Nevertheless, in most cases the result is the same: respondents' answers to factual questions are affected by their partisanship. The aim of this paper is to investigate how partisan bias and to what extent affects the perceived accuracy of factual claims made by politicians (leaders of major political parties in Slovakia). In our research, respondents (N=127) were asked to create their own ranking of credibility of politicians (how much trust a respondent has in a certain political leader). The respondents were later asked to estimate the average factual accuracy of the most trusted, moderately trusted and the least trusted politician. Demagog.SK (fact-checking website) data was used as the baseline data for actual accuracy of politicians. The paper is a survey experiment that also tests the effect of anchoring. The results suggest no positive partisan bias. However, the results show that negative partisan bias is much more prevalent, when respondents portrayed the least trusted politicians in significantly worse light than more trusted politicians. The paper indicates that people on avagare believe that politicians use false claims more often that it is a reality (stigmatization), especially when it is a politician they do not like.
