What is the basis of your experience of philosophers? I know lots of philosophers who are well-versed and interested in, i.a., physics, mathematics, cognitive science, linguistics, biology, neuroscience, psychology, and history. Some of them even make contributions to those fields primarily of interest as works within the relevant field rather than of philosophical interest. This is considered a good thing in modern analytic philosophy. Armchair theorising is considered an important tool, but exclusive use thereof is considered unsound and unwise. I cannot speak for philosophy in general but the sort of milieu to which I've been exposed is not particularly small.
