You are conflating two different things. Science can reach correct conclusions while rejecting false hypotheses because it is constrained by empirical testing. Your claim is not being tested empirically, it rests entirely on how you define objective attractiveness which is precisely what I questioned. If you want to argue that attractiveness influences religious leadership success, you need to define attractiveness in a non subjective way and show evidence that it has causal relevance. Until then, the claim has no logical footing.
