This paper builds upon previous work in which I argue that we should assess a provider's reasons for his or her objection before granting a conscientious exemption. For instance, if the medical professional's reasoned basis involves an empirical mistake, an accommodation is not warranted. This article poses and begins to address several deep questions about the workings of what I call a reason-giving view: What standard should we use to assess reasons? What policy should we adopt in order to evaluate the reasons offered by medical practitioners in support of their objections? I argue for a reasonability standard to perform the essential function of assessing reasons, and I offer considerations in support of a policy establishing conscientious objector status in medicine.
