Ringkasan	A foreign-policy similarity score measures how alike two states' revealed foreign-policy positions are — most commonly from their votes in the UN General Assembly, but also from alliance portfolios or treaty positions. It is a workhorse measure of shared interests, affinity, and alignment in dyadic IR. Häge (2011) shows that naive agreement and the popular S-score can be inflated by chance agreement that arises because states differ in how often they take each position, and proposes chance-corrected indices (Scott's π, Cohen's κ) that better isolate genuine alignment.	Democratic peace analysis is the empirical study of the proposition that democracies rarely or never fight one another. Building on the dyadic research design crystallized by Maoz and Russett (1993), it codes the regime type of each state, constructs dyad-years, and models the probability of militarized conflict as a function of joint democracy alongside controls for power, contiguity, alliances, and trade. The approach has produced one of the most robust empirical regularities in international relations and a long debate over whether shared norms or institutional structures account for it.
