Variations in individual “educational attainment” (essentially, whether students complete high school or college) cannot be attributed to inherited genetic differences. That is the finding of a new study reported in Science magazine (Rietveld et al. 2013). According to this research, fully 98% of all variation in educational attainment is accounted for by factors other than a person’s simple genetic makeup.

This implies that most of student success is a consequence of potentially alterable social or environmental factors. This is an important and perhaps surprising observation, of high interest to parents, teachers, and policymakers alike; but it did not make the headlines.

The likely reason is that the authors of the study failed to mention the 98% figure in the title, or in the summary. Nor was it mentioned in the accompanying press release.

nstead, their discussion and interest focused almost entirely on a different aspect of their findings: that three gene variants each contribute just 0.02% (one part in 5,000) to variation in educational attainment. Thus the final sentence of the summary concluded not with a plea...
