Genetics (based on race) I would argue has nothing to do with intelligence. Intelligence tests assumes everybody has been exposed to the same information and everybody has been given the same tools to properly memorize and apply the concepts under the same circumstances.

I think the likelihood that the child has been exposed to the information needed to do well on intelligence tests can be figured out if they have attended formal schooling accredited to achieve a certain degree=elementary, secondary, post secondary education (FE).The tools needed to get that information to stick in their minds relies more on Family and common social and environmental factors (FSEC).

Students should be screened on their family and environmental and social conditions first (FSEF)and next on grade level achieved (FE) . The higher the FSEF the higher the IQ score. I'm betting that this is independent of race. There may be more of one race than another race based on percentages in the general population but that has more to do with the score on FSEF. How do you calculate FSEF? You give points 1 or 0 to the above.

1 is yes and 0 is No

1. nuclear family is in tact

2. family points out benefits of higher education always or almost always when discussing child's future

3. family takes an interest in the school by going to parent teacher interviews always or almost always

4. encourages education is #1 priority in the child's life always or almost always

5. praises doing well in school always or almost always

5. extended family re-enforces the above always or almost always

6. in the greater community (local neighbourhood) the above is also the case in terms of encouragement, praise and value put on higher education always or almost always

7. Completed Primary School-1-6

8. Completed Secondary School 7-12

9. Completed Post Secondary School (college)

Perfect Score=10, Average=5, Poor= less than 5

*everybody gets at least 1 for breathing

If you score kids on the above I think you will have a greater likelihood of predicting who does well on the intelligence tests and who does poorly.

*Note when I say greater in number I mean in relation to the percentage of the population they represent out of the 100.

In other words if Asians are 10% of the general population than out of 100 test takers there are only 10 Asians out of the whole 100, But they may get 6 out of their 10 get the perfect score that is 60% of their population subgroup.

Blacks could represent 20% of the 100 so that would be 20 people but only 2 gets the perfect score that's 10% of their population subgroup.

Whites would be the balance at 70% or 70 people but out of that 70 only 14 get the perfect score and that would only be 20% of their subgroup.

So the break down out of the 100 with top scores= 6 Asian (10% of the whole but 60% subgroup (SG))

2 Black (30% of the whole group but 10% of SG)

14 Whites (70% of the whole group but 20% of SG)

The representation down racial lines may not be in proportion with the percentage they hold in the sample but still not a result of genetics but rather their family and environmental and social conditions first (FSEF)and next on grade level achieved (FE)

Take the FSEF test in my post and then take the two free IQ tests you will find in the link. Come back and make comments on your score, feel free to share and note your race. Maybe we can generate a discussion on our results when we have our own data here on PH.
