FAQ About Karl Popper

Karl Popper's theory of falsifiability posits that for a theory to be considered scientific, it must be able to be tested and potentially falsified. This means that the theory should make predictions that can be empirically tested and, if found to be false, would demonstrate that the theory itself is invalid. Popper argued that this criterion effectively demarcates scientific theories from non-scientific ones, which often cannot be tested in this way.
