I think Sarah said this here https://srconstantin.posthaven.com/is-stupidity-strength-part-3-evolutionary-game-theory … as 'since spite strategies diminish absolute fitness (ie the number of offspring), spite-dominated populations will tend to shrink towards extinction'. 'Abundance' = 'act as though absolute fitness is fixed' = 'act zero sum'.https://twitter.com/HiFromMichaelV/status/1189487112103419904 …
Why use that definition of abundance? Isn’t the abundant scenario the one in which population & absolute fitness can grow arbitrarily large (positive sum)? In such contexts, spite does out because it cannot produce positive sum growth.
