Testable and Falsifiable Hypothesis
A fundamental characteristic of an effective scientific hypothesis is that it must be testable and falsifiable. This implies that researchers must be able to investigate the hypothesis using scientific methods. Furthermore, aligning with Karl Popper’s falsifiability criterion, researchers must be able to gather empirical evidence that could potentially disprove the hypothesis if it is factually incorrect.

Testing the Falsifiability of the James-Lange Theory
