American Indians have poor vocabularies: Let's continue our look at ethnic groups who report multiple races. Among people saying they are American Indian (AI), they answered one of three races: white, black, other. Here are the mean vocabulary scores for these three categories:

Mean vocabulary scores (General Social Survey):

White American Indians 5.52
Black American Indians 4.65
Other American Indians 4.62

As we saw with Hispanics, more white ancestry is associated with higher scores, but having black ancestry does not lower the average. In fact, the average of all blacks is 5.01, so having AI ancestry lowers the scores of blacks. The pure AI average of 4.62 is lower than the non-white Hispanic mean of 5.34. So clearly, AI's do poorly on vocabulary tests. I imagine that some of this is due to low-quality environments--AI's often have worse indicators than blacks.

New World Indian culture is also awfully taciturn, as Darwin noted when in South America. Indians don't think highly of chatterboxes. I suspect Native American kids don't hear their parents use a lot of words just because their parents don't talk at all that much on average.
