The paper addresses the problem of dealing with real numbers for scores or utilities in decision making, that is, with numbers being positive or negative. The use of non-additive models, as the Choquet integral, entails the possibility of having (at least) two choices when defining the Choquet integral for real-valued integrand, which can be named, after Denneberg, symmetric or asymmetric. The problem is examined in the frameworks of multicriteria decision making and decision under risk and uncertainty.
