Popper's Principle of Falsifiability

Popper's Principle of Falsifiability is a way to distinguish scientific ideas from non-scientific ones. It states that a scientific theory must be testable in such a way that it could, in principle, be proven wrong by evidence or experiments. If a theory makes predictions that can be checked and potentially disproven, it’s considered scientific. If it’s so vague or flexible that no evidence could ever disprove it, then it’s not scientific. This principle helps ensure that scientific ideas are open to testing and critical scrutiny, promoting progress through verification and refutation.
