That's quite likely, but you may get a more positive response if you ask them about statistics (at least in psychology, sociology and political science); it probably mostly depends of what is implied by "maths".

I would say statistics are useful for many social sciences, and that some maths are needed to understand statistics, though things like theorems and proofs and calculus and category theory are not. Calculus is useful for the (smaller) set of disciplines that can use numerical models (mostly economics). Game Theory is useful in law, economics and political science and also requires a bit of maths.
