Falsifiability
Popper introduced falsifiability as a criterion for scientific theories
Popper's falsifiability criterion creates an asymmetry between universal laws and basic observation statements. He argued that while universal laws can be tested and potentially falsified, basic observation statements cannot be verified in the same way. This asymmetry highlights the importance of falsifiability in scientific inquiry.
Example
A theory that predicts all swans are white can be tested by observing swans. If a black swan is found, the theory is falsified.
Popper's falsifiability criterion is crucial for distinguishing scientific theories from non-scientific ones.
