 A distinct and framework-transcendent way of avoiding the impossibility results of judgment aggregation is to give up the binary (‘Yes’/‘No’, ‘True’/‘False’) format of judgments and to assume that they take the form of subjective probabilities or credences. The resulting aggregation problem is that of probabilistic opinion pooling (Stone 1961; Aczél and Wagner 1980; Lehrer and Wagner 1981; McConway 1981; Genest and Zidek 1986; and Mongin 1995). Some key works on it predate the contemporary literature on ‘binary’ judgment aggregation, but the problem has recently received renewed attention.
