Karl Popper's Theory Of A Scientific Test

"Good tests kill flawed theories; we remain alive to guess again."
The above quote of Karl Popper himself makes the overall point of his philosophy clear in a single sentence. He claims that we can never prove a theory, we can only fail to falsify it after many attempts, and if we do falsify the theory, we guess a new one. It does arises the following questions. What is a good test? What is a good theory? Can no guess be the final answer? After these questions are answered I will some reactions on it.
What is a good test?
Popper is an anti-inductivist, but he embraces hypotheticodeductivism and fallibilism. To give you a better understanding of Karl Popper his idea of a good scientific test, I will first describe induction, which Popper thinks

You work your way up to a theory. What immediately pulls attention, and also did not slip Popper’s mind, is that the theories are based only on observation, but in point of fact we never actually see these connections drawn. We can for example not see the universal law of gravitation or Newton’s laws of motion. All what we see is objects reacting on a situation again and again. So, Popper conclude that if we make conclusions based on perception, science cannot claim there is such a…show more content…
Calling it a ‘good’ theory might be impropriate in that sense that Popper is not interested in having a good or even right theory. He is interested in whether a theory should be ranked as scientific, also called the problem of demarcation. He determines a theory qualifies to be truly scientific if it is “incompatible with certain possible results of observation.” The theory has to make predictions that may possibly turn out to be false; it has to be falsifiable by data. Moreover, the possible results that can falsify the theory has to be determined in advance. Theories that are immune to new data are not false, they are just not ranked as scientific. The more predictions there are in the theory and the more specific and risky these predictions are, the more falsifiable the theory is and the better it is.
Can no single guess be the final answer?
If we cannot verify a theory, we can never be a 100% certain about the theory. The longer a theory survives unfalsified, the more confident we can be it is true. Although all unfalsified theories are as likely to be true, science is according to Popper black and white. This might seem pessimistic at first sight, but Popper even quoted Immanuel Kant: “Optimism is a moral duty”. Because the future stays open, we can decide ourselves how it will look in the future. There will always be unsolved problems and we can stay guessing for the answers.
