Of course any notion of genetic diversity would include consanguinity: by definition, less consanguinity = more genetically diverse. The reporting as well as the study's authors explicitly say "diverse genetic backgrounds," meaning that the study's range far exceeds the effects of inbreeding.


Those who are born to parents from diverse genetic backgrounds tend to be taller and have sharper thinking skills than others, the major international study has found.

The effect is pretty small though, so maybe who cares??
