Lower IQ people can’t work in the same jobs, or do the jobs they can get better than lower IQ people. This is a huge part of the reason why blacks talk about ‘oppression’ because they are too dumb to see that they are the reason for their downfall so they blame it on imaginary forces such as ‘white privilege’ or ‘white supremacy’. They don’t even know that 1) whites are the majority in this country and, therefore, have a majority of the jobs and 2) lower IQ people don’t succeed as much or do as better than higher IQ people.

To begin, IQ, along with height are 2 of the most heritable things for humans. IQ is malleable in children, seeing as the heritability of IQ is 22 percent at age 5, 40 percent at age 7, and 82 percent at age 18. So IQ is malleable in children when they are younger so you can change their IQ through the environment, but as they age to adulthood, to quote Jensen, their genes ‘turn on’ and fall to the average for that racial grouping. So in effect, the environment does nothing for IQ in adulthood as it did in childhood. Some people say that IQ is 100 percent environmental, and that is a really stupid position to hold as, through sub-tests and seeing the g loading in them, we can see that the most g loaded tests are highly heritable. People who say that IQ is 100 percent environmental are intellectually dishonest and are true ideologues.

Let’s talk about IQ in relation to job potential. Job performance can be measured in a lot of different ways. Sometimes through how many units per day per hour someone produces, or structured ratings by supervisors or peers or sometimes by analyses of a work sample. With that being said, the correlation between IQ and job performance is .4, with the correlation being higher on for more complex jobs. (pg 72)  It is known that the higher someone’s IQ is, the better they perform at jobs and are better than people who have a lower IQ at that same job. They may be able to memorize more things, be more productive in the workplace or just have better motivation due to being more intelligent and knowing that his skills are being applied correctly in the workplace.

With the above being said, can you think of how that relates to blacks and how they cry oppression that whites hold them down because of ‘white supremacy’? It’s completely nonsensical and sounds completely baseless to anyone with a brain. Now that we know that IQ is highly heritable and is modestly correlated with job success, let’s see what it looks like in regards to getting a job and job applications.

According to The Bell Curve by Charles Murray and Richard Herrnstein, IQ tests are a better predictor of job success than compared to a job interview. They state that, while it may be surprising to many, IQ tests are a better predictor of job performance than any other single measure. This conclusion is drawn from a meta-analysis on the different predictors of job performance which are: (pg 80 and 81):

Predictor                                                                                Validity Predicting Job Performance

Cognitive test score .53
Biographical data .37
Reference checks .26
Education .22
Interview .14
College Grades .11
Interest .10
Age -.01

Source: Hunter and Hunter 1984

As you can see, the job interviews correlation is extremely low. That means that the relationship between the two are not highly correlated, meaning the relationship between them don’t have a good relationship. The cognitive test score (IQ test) is correlated at .53 with job performance. In social sciences, that is a pretty high correlation. A .6 correlation in social sciences is said to be a very high correlation. Think about how blacks act and then think about how they may act at a job interview. With that correlation, .14, being so low, it’s safe to say that they will not get a job based on that job interview. Even education has an extremely low correlation. Yes, your IQ is a great predictor of college success, but according to the table, which was found in a study of 23,000 civilian employees at 3 levels of mental ability (high, medium and low) using supervisor ratings as the measure of performance which also extended out to job tenures of 20 years or more, we see that the correlations that we believe are a good predictor of job success don’t have as high of correlations as we thought they did. We see that cognitive test scores are the best predictor of job success from that table, so with that being said, is it really ‘white supremacy’ or ‘white privilege’ being used to hold down blacks?

Now let’s get on to success in life. I pretty much covered that above, but let’s get more in-depth. According to Linda Gottfredson, the correlation for scores that are averaged has a correlation with job performance at .90. (pg 106) IQ is correlated with increased income, increased wealth, economic growth, livability in a US state, cooperation and life expectancy. IQ correlates negatively with socially undesirable outcomes such as crime, welfare dependence, and illegitimacy. Why people deny IQ having anything to do in life is crazy. All you need to do is look at your local down and out people and see how they act and how that comes to their ability to find and keep a job. You don’t even need to see these correlations and information to see this in real life, all you have to do is observe your surroundings and draw your own conclusions and if you are intellectual, you will see these things and draw the correct conclusions on the matter that don’t involve ‘white supremacy’ or ‘white privilege’.

Now let’s get to crime and how it is correlated with IQ. According to Arthur Jensen in The g FACTOR The Science of Mental Ability, IQ has a well-established correlation between a number of social variables such as poverty, crime, illegitimacy and chronic welfare status. He also states that verbal test scores are somewhat highly correlated with delinquent and criminal behavior than are nonverbal (spatial) suggests that other cognitive factors, in addition to g are most likely responsible for the correlation of IQ with the most common forms of antisocial behavior. (pg 294) Lower IQ is also known to be correlated with a lack of abstract thought and thinking into the future. Thinking of blacks, with an average IQ of 85 (Rushton and Jensen say that some data says 78) we can see how criminality is correlated with low IQ and how  blacks have, on average the lowest IQ and commit the most crimes per capita in America. People may point to that data and say “Whites commit the most crime in America”, and while true, they don’t think of per capita rates as well as the population percentage in the country, which is 63 percent white and 13 percent black. That is what really matters.

The average IQ for a criminal is 84 in America right by the average IQ for blacks in America which is 85. That can not be a coincidence. We see how much crime they commit and how it has an effect on American life in regards to how the media portrays them as Saints in a crusade against ‘white supremacy’ and ‘white privilege’. We see that the problem in the black community isn’t whites “holding them down”, it’s due to their own biology, which they don’t have the average IQ to grasp that it’s them and not the people they blame for their downfalls.

Skin color is also correlated at .92 with IQ in a study of IQ and the countries populations. Skin color was used as a proxy for ancestry and the correlation was .92 for skin color and the rho was .91.

A correlation is a mutual relationship between 2 things. So if the correlation was 1.00, then that would mean there is a relationship between the 2 things being tested. With that number, .92 being so close to the perfect correlation of 1.00, it’s safe to say, that the darker someone’s skin is, the less intelligent they are. You may point me to some outliers, but that is perfectly explained by the relationship not having a perfect correlation. If the correlation were perfect, then that would mean every dark-skinned person’s IQ would be low, but that’s not the case so you get some people who don’t fall into that category.

Rho is a population coefficient or the population Pearson correlation coefficient. It’s a measure of a linear correlation (dependence) between two variables, X and Y, giving a value of +1 and -1 inclusive where 1 is a total positive correlation, 0 is no correlation, and −1 is a total negative correlation. It is widely used in the sciences as a measure of the degree of linear dependence between two variables.

In Rushton’s last paper before his death, he wrote that melanin has been linked to behaviors in species. He conceptualized skin color as a multi-generational adaptation to differences in climate over the past 70,000 years. He proposed life history theory (formerly known as r K selection theory) to explain the covariation found between human and non-human pigmentation and variables such as birth rate, infant mortality, longevity, the rate of HIV/AIDs and violent crime.

So we can see that the darker someone’s skin is, the more likely all of the above variables are to be seen in those with darker skin pigmentation. We can see that skin color DOES matter and anyone who says otherwise has no idea what they are talking about.

So the people harping on about how skin color doesn’t matter, it does and as you can see through this whole post, with IQ being THE best predictor of success in life, we can see how skin color matters as well.

In conclusion, what white SJWs and blacks say in regards to blacks being held down by the rich white men in America is clearly hogwash as I have shown to you in this thread. The black community will not succeed until segregation is put back into place. During segregation, they actually “succeeded” in their own lives because there was a clear separation of whites and blacks. Today, the single mother rate in the black community is 72 percent. 50 years ago it was 24 percent and in the 20s, it was 5 percent. The downfall of the black community is not white people.



  1. […] Right. IQ is the cause of the unemployment rate of African Americans. Not any imaginary forces such as ‘white privilege’. Public schools are more segregated today due to people wanting to be with others genetically similar to themselves. Blacks cause themselves to get shot and killed by police due to their actions during altercations with police officers. Oh no, someone has not politically correct opinions!! She should lose her job and never work a good job again! […]


  2. […] I touched on black crime a bit a few months ago. I will now go more in depth on reasons for black crime. […]


  3. […] they don’t test anything of worth, even after hearing about what it does test is beyond me. I touched on success in life in regards to IQ in this article. IQ tests do mean a lot to life success, along with personality traits (coming in a future […]


  4. […] No the number is not “too simplistic”. IQ correlates with many positives as well as many negatives. Their own IQ limits their aspirations, telling them the truth doesn’t hurt […]


  5. […] No the number is not “too simplistic”. IQ correlates with many positives as well as many negatives. Their own IQ limits their aspirations, telling them the truth doesn’t hurt […]


  6. […] We know that their IQs are innate and that when black and ‘Latino’ IQs are matched at 100, many racial differences disappear. So we can say, with reason, that if a black or ‘Latino’ is poor, they have a higher chance of being gay than whites. […]
