Well that’s terrifying

To elaborate a little on the difference: Grant's argument is that Nordics (Aryans) are the best and are only being outbred by "inferiors" because of social factors. Stoddard's is "every race is out for its own," and that once industrialization gets exported globally,

then the "white races" will be out-competed by the "rising tide of color." It's basically a racist version of a nativist globalization argument, and as such is much more subtle than the "divide up whites into anthropological sub-races" approach.

Separately, Grant's form of interwar racism ("divide up the whites") became less compelling to Americans than Stoddard's biracial ("white vs. colored") approach, after the Great Migration and all that. Grant's is the racial theory of the KKK, Stoddard's is the view of Fox News.
