 These three conditions, it should be noted, are individually necessary for SEU representability, so that any SEU maximizer must satisfy them. In addition, Savage proposes two further non-necessary, aka “structural”, conditions—respectively known as “Non-Degeneracy” and “Small Event Continuity”, as well as a further, necessary, condition of “Eventwise Monotonicity”, which tells us that, under certain mild circumstances, the result of replacing one or more occurrences of a given outcome by another will yield a preferred act if and only if the new outcome is preferred to the original.
