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 intrinsically lean one way or another. It is a devil’s advocate argument, not a argument from a specific position.
The claim that all races have an equal IQ would be a way more improbable claim than saying every race is equal in IQ.
If you have any quantifiable value, especially with something as variable as IQ it's very unlikely an entire race would be equal to an entire other race.
It doesn't have to be about race or about IQ. It could be about any group of people, compare them to any other group of people in terms of their height. It's very statistically unlikely the two groups will be equal in height.
Unless you believe IQ is unquantifiable, or it's magical and god given and not due to evolution in different environments and different cultures.
If every other variable like height, running speed, body fat percentage and so on isn't equal among not just races but cultures, nationalities and so on I don't see why a brain would be the magic organ that's considered to be precisely equal among any group of people
Are you ready for the fire? We are firemen. WE ARE FIREMEN! The heat doesn’t bother us. We live in the heat. We train in the heat. It tells us that we’re ready, we’re at home, we’re where we’re supposed to be. Flames don’t intimidate us. What do we do? We control the flame. We control them. We move the flames where we want to. And then we extinguish them.
Impersonation is treason.
