"What Does IQ 70 Mean for Black And White Kids?"

I've known for over 20 years that blacks have a mean average IQ of 85. I've also noticed they come across as normal people, whereas whites with IQs that low tend to be unusual-looking, such as Otto Zehm, who was beaten to death by a cop (who is now in prison for five years):

With this country's catastrophic economic policies eliminating high-paying working-class jobs and turning what normally would be productive citizens into criminals and parasites , this means many blacks are essentially going to end up on life-long welfare. This also means the destruction of marriage, kids having fathers around, and several generations of sociopathetic young black men who are going to wreak criminal havoc on society. And all because of stupidity, greed, ignorance, the love of power, along with the self-delusion and magical thinking of liberals, who have the mindset of not fixing problems but instead doing things that make them feel good.

Because of the ocean of PC/Cultural Marxism that surrounds us, we are not supposed to notice the truth. No matter how many people die or have their lives ruined....we are not supposed to notice these things.

This article is from the blog Psychological Comments.

"Arthur Jensen was always a paid up member of the select club of psychologists who actually give intelligence tests, as well as writing about intelligence. He was an educational psychologist who believed that every child could learn, and wanted them to have a cafeteria of learning choices, not an inflexible school set meal. He was fascinated by human intelligence, and bewildered by the vituperation of those who were not, and who shouted down his observations. He was thorough in his work, honest in giving his opinions, and steadfast in letting the results have pride of place. He was also very bright. Like many bright people, he assumed that you were probably bright, which was kind of him.

"His first observation was admit that when he tested some children he came out of the assessment session convinced that they were bright. Then he would add up the scores and find that their results were pretty modest. Intrigued by his mistake, he worked out that they had been socially skilled, had presented themselves well, and had fooled him with their charm. Typically, he went on to say that he did not doubt that they would do well in life, because aspects of character other than intelligence can have an influence on success. Equally, he did not cover up his mistake in estimating intelligence, but reported it with interest. He was certainly not a person to boast 'I can tell a person’s IQ at a glance”. Early on he noted that presentation during testing was not always an accurate guide to actual mental ability.

"Then he took his observations further. He noted that when he tested Black kids of say, IQ 70 they came across as normal and their behavior in the playground appeared normal. That is, they related pretty well, had the sorts of interests that other children had, and seemed to be street wise. Seemed to be. They weren’t always able to explain the rules and scoring systems of the games they played, so it depended on how closely you examined their understanding. White kids at IQ 70 were often slightly odd. They were sometimes funny looking in their appearance, and more difficult to make a relationship with. They were often somewhat naive.

"One explanation for the difference is that intelligence tests do not accurately measure black children’s intelligence. Jensen wrote a book on this topic in 1980 Bias in Mental Testing so you can look up the data and his argument in that text. In a nutshell, he found that the tests did not underestimate black intelligence. In fact, they very slightly over-estimated it. He was also doubtful that there were such separate things as black intelligence or white intelligence. In his view there was human intelligence, and the results showed that both people and groups differed in how much they had. (That is something of a simplification, because he also showed there were some differences, not least in the distribution of full scale scores, with black respondents having a more slender distribution, white respondents a more broad and 'normal' distribution).

"What other explanations are possible, other than test bias? Jensen argued that black children of IQ 70 were normal. It was not an illusion. Assuming a black IQ mean of 85, IQ 70 is but one standard deviation below the black mean. Nothing special, and not specially bad from that population point of view. A full 16% of black kids in the US are below one standard deviation for the black population. They were normal black kids. In fact, in terms of normality alone, though not in terms of ability, they were rather like white kids of IQ 85 who are one standard deviation below the white IQ mean of 100. Nothing special. Normal white kids. A full 16% of white kids are below one standard deviation of the white intelligence mean. Only about 2% of white kids are below two standard deviations, IQ 70, whereas 16% of black kids are.

"In summary, IQ 70 is minus 2 sigma for whites but only minus 1 sigma for blacks. Being below IQ 70 is rare for white kids (2%) and pretty common for black kids (16%). Jensen pointed out that there were two routes to mental retardation: 1) simply being at the lower part of the intelligence distribution; and 2) having something wrong with your brain. So, some white kids are retarded because of some injury or illness or genetic disorder, which also makes them “funny looking”, plus some are just naturally dull. A larger proportion of black kids are naturally dull, and some (proportionately fewer) have had an injury or illness or genetic disorder.

"Hence, the difference in apparent normality is real, and is explained by a careful understanding of normal variation in each population.

"Can we test this explanation? Apart from checking all the facts (which appear to be correct) we have a new development in the last decade or two. It seems that average black IQ in the US is now about 90. If that is so, fewer black children will be 2 standard deviations below the mean. IQ 70 will be 20 points below the mean for them, rather than 15 points below the mean, so probably only 9% of black children will fall below that particular cut-off point.

"As a consequence the proportion of funny looking black kids in the under IQ 70 range should have gone up a bit in the last two decades, not because black kids are getting genetic disorders, but because there will be somewhat fewer normal looking backward black children. There will still be proportionately more funny looking white kids than black kids below IQ 70, but the different rates will not be so striking as before.

"By the way, people with IQ 70 can do lots of things. Humans are spectacularly intelligent even at 2 sigma below the Greenwich Population Mean. A great deal can be achieved, even in a group who, compared to everyone else, are considered to be at high risk.

"Finally, the observation that a child can have difficulties either because they are naturally dull or because they have experienced some adventitious insult to their otherwise normal abilities, is not new. Here is a researcher [Francis Galton 1822 –1911] estimating the number of backward children in a population and expressing himself in forthright language:

''We have seen that there are 400 idiots and imbeciles, to every million of persons living in this country; but that 30 per cent of their number, appear to-be light cases, to whom the name of idiot is inappropriate. There will remain 280 true idiots and imbeciles, to every million of our population. No doubt a certain proportion of them are idiotic owing to some fortuitous cause, which may interfere with the working of a naturally good brain, much as a bit of dirt may cause a first-rate chronometer to keep worse time than an ordinary watch. But I presume, from the usual smallness of head and absence of disease among these persons, that the proportion of accidental idiots cannot be very large.'"

The problems blacks are having is not with intellect; nor can they be blamed on inferior genes.

Let's be honest: America has a 'nigger' problem. It is very real, and starts with the Marxist twat in the Whitehouse and ends with the drug dealers in cities like Detroit and their feral children playing the 'knock out' game.

It is a problem of discipline. Bill Cosby is black and tells black kids to 'Pull up their pants, speak English, do well in school and do the best they can.' Buckwheat Obama tells them all their problems are Whitey's fault. He defends and supports feral niggers like Trayvon Martin, and racist whores like Al Sharpton and Jesse Jackson.

We need to stop making excuses for blacks and hold them to the same standards we hold for ourselves. Blacks have produced some of the finest intellects of our time, we know they can do it, we know that 9 times out of 10 that training and education trumps genetics.

The world's problems are not that difficult.

I have no problem with the concept of "multiple intelligences." But this just underscores how precisely different groups evolved to fit different ecologies. The idea that street-smarts or spatio-temporal smarts translate to "playwright" or "mathematician" or whatever other high-falutin' occupation we think needs more diversity is absurd.

No, we do not know this.

Circling back to this excellent post, I saw a white man like Otto in a government office the other day. He wouldn't have hurt a fly. By contrast, there are plenty of sub-85 IQ blacks who can size you up, track you to an ambush point, and break your jaw with one carefully calculated and well-rehearsed punch.

That's what is behind the whole raft of death row appeals based on mental retardation. White judges and defense attorney cannot comprehend how a 70-85 IQ person can be a cold-blooded killer. Because in their life experience, their white family members or friend's family members with IQ's in that range are just friendly retards.

I worked for a year in a nursing home in college, met many like Otto, and they were friendly and harmless. Can't say that same for any black of similar or even higher IQ.

I worked for over two decades in a north-east Ohio public school system that is slowly transitioning from all white to predominately black. Everything you say here is true. I watched in disbelief as the district tried one thing after another to educate the huge numbers of black students who were failing in droves. Million of dollars were (and continue to be) spent on this lost cause. What finally drove me to leave was the escalating levels of violence that I was forced to deal with on a daily basis. I watched my white colleagues, many of them very smart people who thought they could "change the world," crumble before the reality of the situation. Many of them aged prematurely, or took to drink, or developed mental illness.
