Research Type Theoretical We show that on discrete scales it is essentially impossible to do so, while on continuous scales we can characterise the rules meeting these requirements as those that compute a weighted average of the endpoints of the individual intervals. Our main technical results show that (i) on discrete scales it is essentially impossible to design rules that are faithful to both representations (the only exceptions are so-called dictatorships), while (ii) on continuous scales a rule is faithful to both representations if and only if it is a weighted averaging rule.
