Lipton’s “loveliest explanation” invites exactly the bias this claim denies. People find explanations lovely when they already like them. Religious believers will find religious explanations lovely.

Loveliness is Lipton’s technical term for explanatory depth and unification, not aesthetic appeal, and he argues at length that it tracks likeliness. The bias worry is real but symmetric: naturalists find naturalistic explanations lovely. The corrective is public criteria, which is why the arguments on this site try to state what each hypothesis explains and what it leaves out, so that you can check the scoring rather than take the verdict on trust.
