Karl Popper criticized Marxism for being unfalsifiable and thus unscientific. He argued that its predictions were so vague they could not be tested against reality. When predictions failed, Marxists would make ad hoc adjustments to their theories rather than abandon them, rendering them immune to empirical refutation. This lack of falsifiability undermined its credibility as a scientific theory.
