IQ in inbred children (8-12 years old) is found to be lower (69 in rural and 79 in suburban populations) than that of the outbred ones (79 and 95 respectively). The onset of various social profiles like visual fixation, social smile, sound seizures, oral expression and hand-grasping are significantly delayed among the new-born inbred babies." (Indian National Science Academy, 1983 Consanguinity Effects on Intelligence Quotient and Neonatal Behaviours of nsari Muslim Children").
If I remember rightly 100 is normal. Even the intelligent ones, who live in cities are respectively not so smart. The Muslims in rural areas must be really dumb. 69 is hard.
Koko the speaking gorilla scored much better:
