He saw how Einstein had been critical f his own theory, constantly trying to pick holes in order to disprove or, as Popper saw it, improve it. This contrasted sharply with the attitude f Marxists and Psychoanalysis's who, it seemed to Popper, created theories and then re-interpreted them to suit any given situation. This first encounter with empirical evidence and its foundation for the proving f theories would lead him to his eventual way f thinking about falsification theory.
Karl Popper argues that scientists should start with a hypothesis, or a statement that is to be tested. The statement should be precise and should state exactly what will happen in particular circumstances. On the basis f the hypothesis it should be possible to deduce predictions about future happenings. According to Popper it matters little how a scientific theory originate, it does not have to come from prior observation and analysis f data.
Popper denies that it is even possible to produce laws that will necessary be found to be true for all time. He argues that, logically, however many times a theory is apparently proved correct because predictions made on the basis f that theory come true, there is always the possibility that at some future date the theory will be proved wrong or falsified.
Popper argued that scientific progress required a ground work f structure and rationali ...
