Popper argued at the core of true science is a continued effort to attempt to falsify a theory with new predictions. That science is when we accept it as our duty to continue doing this until we are successful is falsifying the theory—and then to try and do it again. If we fail in our attempts, we form a new hypothesis and chart a new path to proving the theory wrong. As Popper stated, we refute the previous hypothesis and make a new bold and risky claim—and then try and dispute it again.

Popper also grappled with the problem, 'When should a theory be ranked as scientific?'. Like Falsification in Part I, Popper was a major contributor to the differentiation between science and pseudo-science. Popper wished to distinguish between science and pseudo-science and set out to create a way to differentiate between 'pseudo-sciences' such as astrology which find its basis is empirical evidence based on observation. https://www.youtube.com/watch?v=8dmOmprI0v4
