Shouldn't the null be that there is no difference in IQ between races. You either find statistically significant data and void the null or find nothing.
No, null hypothesis doesn’t lean one way or another.
It does not assume that in the absence of evidence one or the other is more likely to be true.
Null refers to “what ever you think is the reality there is really not the reality”. It is a devil’s advocate argument, not a argument from a specific position.
Right. And what science strives to do is prove the null hypothesis incorrect when testing a hypothesis.
