Is a dedicated career built solely on peer review currently financially viable?
Answer
No, a career purely in the act of reviewing externally is not viable for financial subsistence
Currently, most academic journals do not offer payment for review work, treating it as an expected service. While alternative recognition like vouchers exists, these do not translate into a sustainable, full-time income required for subsistence.
