Why Africans are at par with Europeans on intelligence:-
As shown by every possible estimate, average IQ in Africa is 87-92. Average IQ of Europe is 97 (100 for UK, 95 for Southern Europe).
I will also clarify "why Northern Euros have higher average than Southern Euros" later on.
The gap between Europeans and Africans measured via standardized tests as of 2016 is 5-10 IQs.
What is 5-10 IQ as per the results of Raven's Progressive Matrices ? Here is a number of question solved v/s IQ results, done on a very reliable software:-
Total questions: 60,
Number of questions solved: N,
N: 60, IQ: 138
N: 57, IQ: 124
N: 54, IQ: 116
N: 48, IQ: 108
N: 42, IQ: 100
N: 36, IQ: 92,
N: 30, IQ: 84

As can be seen in the performance by race in UK, Indian and Chinese minorities in the UK outscore whites by 1 Standard deviation (115 IQ). Indian and Chinese minority make up 3% of UK. High skill immigration from two Asian nations alone makes up "0.45 IQ" jump in UK. And there are high skilled immigrants from 50 odd nations in UK, most of which score very high on IQ tests.
Imagine what it will do to overall IQ in say Singapore where 40% of the population is "high skill immigrants from all over Asia". It doesn't really make sense to compare IQ results in UK with Africa (one which is net receiver of cognitive elites and another which is a donor).
It does make a significant difference in overall IQs. Take the example of Blacks living in UK.
As shown in the UK results, Africans in UK score at par with white Britishers in schools. 3% population in UK is Africans.
Africans have lost by "0.12 IQ" just because of smart migration from Africa to one white nation, UK (in recent times).
It is well estimated that if you include the effects of high skill immigration "out of Africa" in 1950s and there-after to USA, UK, etc., etc., it will lower the overall IQ of Africans by 1.8-2.3 IQ.
While high skill immigrants from all over Europe, India, China, south East Asia has increased the IQ of UK by "2-3 IQ points".
As can be seen in the UK GCSE results, the Irish minority in UK outscores British whites by 7 IQ. The high skilled immigrants from Ireland alone increase the IQ of UK by 0.7 IQ.
Which means that the IQ difference between UK and Africa (10 IQ points) is inflated due to "high immigration out of Africa" and "high skilled immigration" to UK.
If you remove the high skilled Irish, Indians, Bangladeshi, South East Asian, Africans and Chinese immigrants out of UK; the whites (native to the UK) will score 97 IQ.
If you include all high skill immigrants that have left Africa for calculating African IQ, it will be 92 IQ. So, here you can compare the original IQ potential of Africans and highest scoring white nation in terms of original population (not adjusting for immigrants in and out).
Now, let's compare what the differences in professions can do to "average IQ" data-set.
UK has 20 pc of population studying till university level. Africa has mere 2 pc.
It is well documented that people who attend higher education score 20 points higher (not because they are more intelligent), but because they are trained for problem solving.
This itself can cause an IQ gap of 3.6 points between Africans and Europeans.
Now, lets look at the genius level IQs in Africa. Best is to compare mathematical olympiads (https://www.imo-official.org/results.aspx), There have been several incidences of African nations (Nigeria) outperforming many white nations and winning medals at IMO which is a clear indication of genius level IQs in Africa, at par with top 0.001 percentile of European population.
So, overall I conclude the following stuff:-
1. IQ published for Africa by Lynn and Vanhenen is obtained by careful selection of low IQ studies, dismissing high IQ studies as such.
2. Long term IQ potential of Africans is same as African Americans, 7 points below Africans in UK which is a case of smart migration.
3. IQ gap between Europe and Africa is unlikely to be because of "evolution" and such gaps can be entirely because of "immigration", "differences in professions", or "differences in breeding patterns" in different populations.
4. Africa has significant population of high IQ individuals (at par with top 0.001 pc whites) and African nations will keep on winning bronze medals at IMO outscoring many white nations. And Africa will be a superpower due to the presence of such "high IQ individuals".
The difference between Africans and Europeans on IQ tests is 5-6 questions which is considered a negligible difference. It doesn't really make sense to advertise the fact that one nation solved "mere 5 questions" more than another nation like a "racial propaganda". Anyone knows that by proper tuition and education, anyone can solve 10-20 questions higher than his current performance on IQ tests. Isn't it. And it is well known that Europeans spend much higher on tuition and academic improvement than Africans.
The gap between the performance of Africans and Europeans on IQ tests can purely be because of "differences in professions" between the two populations or just because of "high skill immigration" and can be "far from being genetic" as mentioned by evolutionary theories propagated by few psychologists and in this article I will show the same with accurate calculations.
First, lets discuss the factor of immigration. UK and USA which are net receptors of high skill immigrants from all over the world, should not by any means be set as a benchmark of IQ.
How does immigrants help increase the IQ.
Here are the school results from UK:-
