Evolutionary arguments are complementary to work done in other cognitive sciences. Both are important to understand the complete picture of how we behave. Many evolutionary explanations begin as 'just so' assertions, but so does anything in science, really. Evolutionary arguments can be very difficult to test because our knowledge is incomplete. There are many interacting variables at play and we can't go back in time. It's doesn't mean we can't test hypothesis, though, and there is a huge body of evolutionary behavior research that shows how much we can do.
