Race and IQs

[Anomalocaris]

If Huggy's contention is that the races are inherently equal in intelligence, I've yet to see good evidence for that.  So the question is, Huggy, are you saying that you believe the inherent intelligence of the races is equal, and if so, what justification do you have for that belief?

That's not how the null hypothesis works.  Why would the default position be that every human is different?

The null hypothesis simply states that whatever you are seeking to demonstrate is really not there, despite what you think are the evidence for it being there.

The null hypothesis could either be 1.  there is a difference in average intelligence between two groups, or 2. there is not a difference in the average intelligence between two groups.

Null hypothesis 1 is applicable if the proposition being tested is average intelligence is essentially the same between groups.  Null hypothesis 2 is applicable if the proposition being tested is average intelligence is essentially different between groups.

Null hypothesis makes no supposition about what the base case assumption should be. It is simply the counter to wherever the proposition being advocated.

For a proposition to be credited as being supported by evidence, it is necessary to show that if the counter to the proposition is actually true, there is no significant probability that the same evidence could nonetheless still be found.
