Final answer:
The epistemic value of moral oughts lies in their basis on principles that promote human well-being and positive interpersonal interactions.
Step-by-step explanation:
The epistemic value of moral oughts compared to other assumptions such as humans having sex 50 times a day or humans playing soccer is that moral oughts are based on principles that promote human well-being and positive interpersonal interactions.
While there may be an infinite number of assumptions one can base an ought out of, morality provides a moral framework that is based on reason, human nature, and societal needs. The evolution of humans as social beings contributes to our tendency to care about moral oughts as they are essential for the functioning and harmony of human communities.
