This paper discusses a challenge for comparativists about belief, who hold that numerical degree of belief (in particular, subjective probability) is a useful fiction, unlike comparative belief, which they regard as real. The challenge is to make sense of claims like ‘I am twice as confident in A as in B’ in terms of comparative belief only. After showing that at least some comparativists can meet this challenge, I discuss implications for Zynda's [2000] and Stefánsson's [2017] defences of comparativism.
