 In the Ellsberg pairs, assuming the “best estimate” is that yellow and black each have probability \(\lfrac{1}{3}\), this will assign \(\varrho(\lfrac{1}{3})\) to \(f_2\) and \(\varrho(\lfrac{2}{3}) + (1 - \varrho)(\lfrac{1}{3})\) to \(f_3,\) making these acts disprefered to \(f_1\) and \(f_4,\) respectively, as long as \(\varrho \lt 1.\)
