The person behind these results is a fraud. His work is one of the worst example of data manipulation in psychology, and thus this map has no scientific validity.
There was no standardized method to infer IQ values. Many of the "IQ tests" were rather reaction tests, mirror tests or draw-a-man tests. It was always administered in the colonial lingua franca. Lynn collected the results from pre-existing studies and excluded the majority of the samples that did not match his agenda, e.g in Nigeria and Ghana.
For Equatorial Guinea, they tested 50 retarded kids in a mental institution in Spain, that's how you find 59.
For other countries like Somalia or Ethiopia, they took a small group of refugees in another country, still children.
For other countries like DRC, they took a small group of kids in the middle of a major conflict.
For almost half of the nations, they "estimated" the IQ based on neighboring countries... Or on the workforce composition (more farm workers supposedly implying a lower average IQ).
The data is also from the 20th century. Famine, war, diseases, unsanitary conditions and illiteracy have been reduced considerably in 3 decades, all of which affect IQ.
