الملخص EN

The study explores Lynn-Flynn effect in Saudi Arabia by measuring the national increase of intelligence in 33 years between 1977-2010.

The Standard Progressive Matrices (SPM) that was standardized by Abu Hatab et a I.

(1977) was applied to a representative sample of 4932 participants from Mecca Province.

For the purpose of the present study, the age group 8-18 years was selected from Abu Hatab sample.

The selection consists of 3625 participants, 2281 (62.9 %) males, and 1344 (37.1 %) females.

The SPM was applied without alteration in 2010 to a representative sample of 2007 participants from Mecca Province, age 8-18 years.

The sample consists of 806 (40.2 %) males and 1201 (59.8 %) females.

The most remarkable finding of the present study is that males' IQ in 1977 was 53 points higher than females, while at the beginning of the millennium females’ IQ is 1.8 points higher than males.

The study also stumcd that there is an increase in the level of performance on SPM for younger age groups compared to elder ones.

It showed that the national intelligence in Saudi Arabia has increased by 8.54 points in 33 years from 76.06 in 1977 to 84.59 points in 2010 according to the Greenwich British norm.

The rate of increase per decade and generation was 2.59 and 7.76 points respectively.

This finding means that the present generation in Saudi Arabia is smarter than the previous one.

Finally, 10 assumptions as possible causes for the increase of national intelligence were suggested, as well as 10 implications for further studies to be investigated by students of psychology in Arab world and in the diaspora.
