Recall that performance is exactly the heuristic against which novelty search compared favorably in Chap. 5. There’s no reason to suspect that the same heuristic, but used one level up (to guide the AI community as a whole instead of a search algorithm), will avoid the problems plaguing objective-driven search. When performance is the rule of thumb that filters which algorithms are shown to the larger community, all other kinds of stepping stones are rejected and ignored.
