list of interpretations from my reading of it the third item in this list doesn't fit with the way the list is introduced the contemporary scholarly debate about race and intelligence involves both the relatively uncontroversial experimental results that indicate that average iq test scores vary among racial groups and the relatively more controversial interpretations of these iq differences in general contemporary interpretations of the iq gap can be divided into three broad categories culture only or environment only interpretations that posit only non genetic causes e g socioeconomic inequality or minority culture membership that differentially affect racial groups and partly genetic interpretations that posit an iq gap between racial groups caused by approximately the same matrix of genetic and environmental forces that cause iq differences among individuals of the same race insufficient data no meaningful interpretation can be made based on available evidence the problem seems to be that isn't an interpretation but rather the lack of an interpretation or the inability to empirically distinguish between alternatives and i've been brainstorming for a simple fix but i can't think of one the best alternative i can think of is to remove from the list and add a follow up sentence saying something like a large minority think there is insufficient data and no meaningful interpretation can be made based on available evidence this isn't as nice because more experts chose than in the s r survey july utc
