This paper introduces "social decision frames" to analyze strict majority reasoning within finite electorates. It identifies a coherence criterion for qualitative majority judgments, which precisely characterizes representability by finitely additive measures. The research also develops a minimal logic for strict majority reasoning and applies these findings to refine a classical representation theorem for weak qualitative probability structures, establishing a May-type characterization for ordinary strict majority rule.
