Answer 1

Colloquially, the null hypothesis establishes that no two things are correlated until they are demonstrated to be correlated.

It’s a way to start logic from zero, without bringing along presumptions from “common sense,” generalizations, genuine misunderstanding, pseudoscientific belief, or sociopolitical/religious bias.

Before a criminal trial, the null hypothesis is that the defendant is “not guilty,” and it is the prosecutor’s obligation to demonstrate that the defendant is correlated with the circumstances of the crime, thus “disproving the null.”
