The Harrison Prize-winning paper (best 2023 article in @PolStudies) uses @csestweets data: "A crucial advantage of this dataset...[is that it offers] more variance on this question in terms of contexts and, most importantly, in terms of quality of democracy." Abstract below⬇️ "Citizens who voted for a party that won the election are more satisfied with democracy than those who did not. This winner–loser gap has recently been found to vary with the quality of electoral democracy: the higher the quality of democracy, the smaller the gap. However, we do not know what drives this relationship. Is it driven by losers, winners, or both? And Why? Linking our work to the literature on motivated reasoning and macro salience and benefiting from the Comparative Study of Electoral Systems project—covering 163 elections in 51 countries between 1996 and 2018, our results show that the narrower winner–loser gap in well-established electoral democracies is not only a result of losers being more satisfied with democracy, but also of winners being less satisfied with their victory. Our findings carry important implications since a narrow winner–loser gap appears as a key feature of healthy democratic systems." journals.sagepub.com/doi/10.… @Jf_daoust @r_dassonneville Richard Nadeau
