Muslims converted Christians and Jews by force into Islam, thereby driving up the average IQ somewhat. If not for the forced conversions, the average IQ would be what, 70?
14 of the bottom 17 are large muslim populations, ranging from 78 IQ average down to 59 IQ average.
The highest average IQ muslim nations are Malaysia (#39 with 92 IQ) and Indonesia (#44 at 89 IQ). The other muslim nations predominate the bottom half of the list.
Egypt, Saudi Arabia, and UAE are tied for #60 with average IQ of 83.
The USA is now down to average IQ of 98; it was 100 in 1980, when the population was about 270 Million. Bringing in 50 Million sub-human immigrants over the past 35 years, that two percent drop represents a plunge into the abyss for the USA.
