 These rules in this section allow but do not obviously explain the Ellsberg choices unless supplemented by an additional rule (e.g., Levi’s more complicated story or one of the rules from  section 4.3.1),  since any choice between \(f_1\) and \(f_2\) and between \(f_3\) and \(f_4\) appears to be E-admissible, maximal, and non-interval-dominated.
