I think making claims without substantiating them, including claims that are in contradiction with claims others have made, is a more virtuous move than calling (acceptance of) other claims unwarranted. It’s invisible whether some claims are unwarranted in the sense of actually not having even a secret/illegible good justification, if relevant reasoning hasn’t been published. Which is infeasible for many informal-theory-laden claims, like those found in philosophy and forecasting.
