A new study from Edinburgh and King’s College in London studied 1890 pairs of identical twins over the course of nine years.  The twins took IQ tests at age seven, nine, ten, 12 and 16.  The results showed that those children who were better at reading had a higher general intelligence.

Because the study used identical twins, genetic and environmental factors were able to be set aside.  The results showed that even with identical twins, if one twin could read better that twin would do better at IQ tests.

This fascinating result shows that being better at reading does more than allow you to read better, it speaks to being deeper than that and more profound.
