They're forbidden to - I think this was touched on in the episode or two back in discussing why the 3s were boxed. Perhaps they've deliberately "de-activated" any ability they might have to know? Maybe the simplicity of the raiders in some way allows them to know whereas the more advanced skinjobs can't?

I bet the hybrids know too - they have that whole "cosmic knowledge" thing, so that would make sense. Or maybe the hybrid passed that information along to the raiders somehow?
