Document Summary

The role of nature: genetic effects on iq. Data shows that increases in genetic similarity are associated with increases in. Over 11k sets of twins, very robust data sets. Close to a . 9 correlation between iq and genetic similarity. This correlation is similar to the same person taking the same iq test twice. The y axis of behavioral genetics shows the correlation in iq, not the actual iq. Identical twins are not smarter than the average set of people. As you increase genetic similarity, increase in similar iq. Unrelated subjects have very different brains (very dark purple) Fraternal twins have more similar brains (green and blue) Identical twins have physically similar brains (red and pink) Had 233 pairs of twins (fraternal and identical) look at random pictures. Point of focus of was tracked as they looked (heat map) Can use heat map to see that people with similar gaze patterns are actually twins.
