 The correspondence between selection function models and relative modality models is very direct. The correspondence between selection function models and ordering models is less obvious. How can we explain it? If we interpret similarity relations as preference relations, we can import the insights gained in rational choice theory to the analysis of conditionals (Sen 1970; Suzumura 1983; Aleskerov, Bouyssou, &amp; Monjardet 2007; applications to nonmonotonic reasoning are in Lindström 1994 and Rott 2001). If the Limit Assumption is satisfied, then we can simply identify \(f(w,U)\) with \(\min_{\prec_w} (U)\), for all \(U\subseteq W\). For the converse direction, we can use the revealed preferences, defined by
