A Study of Intelligence in Tajikistan

Alisher Khosimov and Richard Lynn

Abstract

The Standard Progressive Matrices Plus (SPM+) was administered in Tajikistan in 2016 to a sample of 674 13- to 15-year-olds. This is the first study reporting cognitive test results from this country. The mean British IQ of the sample was 88, which is comparable to results of similar studies in other countries of Central Asia. There were virtually no sex differences.
