Because statistical analyses are inherently probabilistic and all research methodologies contain potential flaws, absolute scientific proof does not exist. Instead of definitively proving that a theory is true, systematic empirical research provides varying degrees of scientific evidence. Consequently, theories are continually supported, weakened, or refined based on new data rather than being permanently proven.

Scientific Proof

Rather than trying to draw strong conclusions based on the findings of one single study, scientists evaluate theories by looking at the overall trends across a body of research. By assessing a large number of partially flawed studies, researchers can reach more meaningful conclusions than they could by waiting for a single perfect experiment.
