In the case of DK, the hypothesis is that there is a bizarre relation between perceived skill and actual skill. The null hypothesis is that is there no relation or correlation between perceived skill and actual skill. A researcher would perform an experiment. If researcher observes statistically significant results. Then the researcher can reject the null hypothesis, and say the theory is valid. If researcher does not observe statistically significant results. They can only say their experiment doesn't support the theory.
