"communism" relates to a whole body of different theories, some of which are falsifiable and some which are not and are backed by empirical evidence. i'm assuming you're specifically referring to historical materialism, as popper's insistence that it is unfalsifiable is a common criticism. popper's idea of falsifiability is a maxim, not a scientific law. when marx and engels called it scientific socialism, the understanding of 'scientific' was different than in popper's time. scientific socialism really would more aptly be called 'structured socialism' in today's language, but that would take away from the parts that do make it scientific, in that marxism doesn't shy away from testing out its own theories and reassessing what it got wrong. that isn't falsifiable, but it is in theory repeatable, which makes it a scientific framework, the only problem is that, like with every other sociology, psychology, and economy experiment, we don't have a parallel world that we can hold as the test group, so the theories are inextricable from history. if that logic isn't good enough for you, there are plenty of others who have contested the claim of it being unfalsifiable as well.   ution06-en.html others have challenged the to theory of falsifiability itself   ot.com/2009/08/revisiting-popper.ht ml?m=1
