HOWEVER, it's scientifically known that Black people reach their peak faster compared to other races.

I hadn't heard that. Do you have a source?

This should theoretically explain why the IQ gap actually gets BIGGER over time

I believe that's common for any IQ gap. Kids that are behind fall further behind as their education progresses, regardless of their race.

Black people are born quicker

Black children reach puberty faster than other races

It actually all fits in with Rushton's theory of R/K selection in humans.

Species that are considered very intelligent, have the smallest amount offspring while also spending the most time raising them. Species that are considered less intelligent have the largest amounts offspring while spending very little time with them.

Do you have a source for the earlier peak in terms of IQ?

Flynn took a different approach. The black-white gap, he pointed out, differs dramatically by age. He noted that the tests we have for measuring the cognitive functioning of infants, though admittedly crude, show the races to be almost the same. By age four, the average black I.Q. is 95.4—only four and a half points behind the average white I.Q. Then the real gap emerges: from age four through twenty-four, blacks lose six-tenths of a point a year, until their scores settle at 83.4.

I recall there was another article out there by Charles Murray, but this one is close enough.

But every study on the racial IQ gap has made the same observations. Anytime Blacks reach adulthood and get tested, their average IQ is ALWAYS 15 points behind adult Whites. This type of gap has existed since the first world war. It has never changed in a 100 years, and it's safe to say it's genes that cause that final difference.

Philippe Ruston once went to South Africa and tested the Blacks in their own continent. Same results. The Black students did worse than the White South Africans by 15 points.

The race gap is universal. Nothing but actual eugenics can help fix the black race since other races evolved higher intelligence, while they stayed behind in Africa.

Once kids fall behind that accelerates. That's not the same thing as reaching a peak earlier. Unless by peak you mean "leaning the fastest". In which case everyone peaks as an infant.

There's a lot less data for over 25s and IQ tests.

For instance Black Americans Reduce the Racial IQ Gap, Dickens and Flynn, PSYCHOLOGICAL SCIENCE (2006), suggest that the gap has closed more slowly in over 25s, but the data was insufficient to show that it was more slowly at a 95% confidence:

The rate of gain for Blacks 25 and older in the WAIS data is smaller, but our data yield no reliable estimate for that age group. This is because the WAIS standardization samples included only a small number of individuals ages 25 to 74. The estimated rate of gain has a 95% confidence interval of 0.129. That is too large to allow us to reject the hypothesis that older Blacks had the same rate of gain as those under 25.

That's incorrect. Black children still fall behind 100 points, which is considered the standard.

So yes, they've already hit their peak, compared to other races who do better than them. Both as children and adults.

There's a lot less data for over 25s and IQ tests.

What exactly is the significance of selecting for IQ's of 25 year olds vs 18? Especially when 18 is usually the age when teenagers have graduated High School and are allowed to attend University or College. By the time they actually finish some programs, they might already be in their early 20s. It's redundant, unless you have proof young adults get super smart near the end?

The under 25s all showed that Blacks had reduced the racial IQ gap. The over 25s they didn't report on, because the sample size was too small.

The under 25s all showed that Blacks had reduced the racial IQ gap.

The gap is still 15 points. We've had Rushton and other scientists confirm this all the way into 2005.

But not only that, why aren't you including Asians in this comparison as well? Do you believe for example, all blacks have the same or greater IQ than Japanese or Chinese people? Do you have proof of how can this be possible?

The over 25s they didn't report on, because the sample size was too small.

And what do you think the same White IQ looks like at over 25 years old?
