 Proponents of the argument from fine-tuning for design argue that, in view of the required fine-tuning, life-friendly conditions are highly improbable if there is no divine designer; see Barnes 2020 for a careful case for this claim. Thus, the conditional probability \(P(R\mid \neg D)\) should be set close to zero. In contrast, it is highly likely according to them that the constants are right for life if there is indeed a designer. Thus the conditional probability \(P(R\mid D)\) should be given a value not far from \(1\). If a sufficiently powerful divine being exists—the idea goes—it is only to be expected that she/he will be interested in creating, or at least enabling, intelligent life, which means that we can expect the constants to be right for life on that assumption. This motivates the likelihood inequality
