What's the profile of a person who believes astrology is scientific? (Answer: the exact opposite of me)

Clearly, anyone who believes that astrology is scientific doesn't understand what science is, but how common is this belief, and what's the statistical profile of a believer?

The General Social Survey asked respondents the question with answers varying from "very scientific" to "not scientific" at all (sample size = 5,548). 36.6% of people said astrology was at least sort of scientific. That's a lot of dummies.

Here are the factors that predict belief (standardized OLS coefficients):

Predictors of thinking that astrology is scientific

Female   .09
Black   .13
Other race    .04
Age   -.07
IQ   -.17
Educational level   -.11
Church attendance   -.04
Political conservatism   -.04

All of the coefficients are statistically significant at the p < .01 level (or higher, two-tailed test).  So the profile looks like this: female, black (vs. white), other race (vs. white), young, unintelligent, uneducated, non-churchgoer, and liberal. The coefficients indicate the strength of the prediction: IQ is the best predictor of thinking astrology is not scientific.

Who has happier marriages--the religious or irreligious?

I haven't annoyed my irreligious friends in a while, and the only person who reads this blog that I don't want to be annoyed occasionally is me.

A common type of contemporary thinking goes like this: The more slowly, deliberately, and freely people decide to get married, the happier their marriage will be. Following this line, highly religious people should have the most miserable marriages because they marry younger. They might feel more pressure from family to get married and might want to avoid the temptations experienced all too often as singles.

The General Social Survey asked respondents how often they attend religious services and how happy their marriages are (if they are married).  The sample size is 11,543:


















The pattern is clear:  satisfaction with one's marriage rises with church attendance, especially among more frequent churchgoers.

In recent years, I've been shifting away some from the conservative sociologist's view that traditional institutions (e.g., church, marriage) improve people's lives toward the naturist view that people with certain genetically-influenced traits (i.e., agreeableness, conscientiousness) select themselves into traditional institutions. There could be some truth to both views.

Marriage and religion are universal practices, and as NN Taleb instructs us, institutions that have been around forever are probably doing something for us whether we understand it fully or not.

The BIGGEST sex differences

A study by John Archer reviewed meta-analyses on psychological sex differences, so we're talking about hundreds of studies. I will highlight the largest differences; those with means that are at least eight-tenths of a standard deviation apart. For the non-stats people among us, that is a very big gap.

Largest sexually dimorphic psychological traits (difference in sd units)

Homicide   2.54
Rape   2.32
Mate choice--Age difference   2.00
Violent computer-game use   1.41
Occupational interests   1.39
Systemizing   1.21
Pain tolerance  1.17
Fear in real-world situations   -1.16
Violent crime   1.11
Engineering interests   1.11
Partner homicide   1.06
People-things distinction   -.93
Empathy   -.91
Weapons use  .88
Sexual v. emotional jealousy  .87
Revenge   .83

Among the traits that Archer included, there is no bigger difference between the sexes than violence. Men are the violent sex and love it much more than women (i.e., violent video game use).

Male superiority in visuospatial ability is talked about a lot, and there is a difference, but it is not large enough to make the list. Interest is where the big gap exists. Men are much more likely to have an interest in engineering, making systems, and working with things over people.

While I've admired my wife's ability to suffer the pains of childbirth repeatedly, experimental research indicates that men can tolerate pain much better than women. Women are much more fearful of being harmed in real-world situations. This might figure into male willingness to get his ass kicked in a fight.

Women are the empathetic sex. They are much less likely to desire revenge. They get jealous about their man having romantic attachments, while men are much more concerned about sexual betrayal. Women desire older, resource-possessing men, while men desire younger women who have lots of reproductive potential.

These sex differences are what evolutionary theory would predict: men compete with each other, sometimes violently and vengefully, for access to mates.

There must have been benefits for women to be more sensitive to the feelings of others--effective childcare comes to mind--and men must have benefitted from a greater orientation to the analysis of systems. Strategic thinking for hunting and war?


UPDATE: Archer neglects to include perhaps the largest psychological sex difference: males are overwhelming attracted to females, while females are overwhelmingly attracted to males. The exceptions are noise. And the evolutionary reason is obvious.

Is the black-white IQ gap caused by income inequality?

Some liberal researchers contend that the black/white IQ gap is due to income inequality. If that is true, then changes in the IQ gap over the past few decades should parallel changes in income disparities.

Here are graphs for males and females generated from General Social Survey data (sample size = 25,589).  (For many analyses, it is appropriate to use median income, but we are interested in inequality so the mean makes more sense).

Mean individual income (constant $)--males



Mean IQ--males

















For men, the black-white gap in income grew over the past five decades. The gap in constant dollars is $12,300 in the 1970s and $18,400 in the 2010s. This kind of widening should lead to a larger IQ gap, but the IQ difference shrunk from 10.6  to 8.2 points over the same period.


Mean individual income (constant $)--females



Mean IQ--females

















We see the same widening income gap for women from $1,300 in the 1970s to $5,900 in the 2010s.  Over the same period, the IQ gap dropped from 11.6 to 8.6 points.

Once again, the trends contradict the liberal prediction.

Now, you might respond that GSS data do indicate a narrowing of the racial IQ gap over the past five decades, and indeed they do. We don't know for sure why that is--it might be due to the horrible black high schools in the South getting better in the last few decades (perhaps vocabularies can be improved a little with decent schools)--but the point of this post is that it does not look like the difference in black and white IQs is due to the fact that whites make more money.

UPDATE: Sean Last posted this Pew graph which shows a widening in the black-white income gap:

An analogy that might offend

I'm surprised I've never run across this analogy for homosexuality that now occurs to me.  Imagine a group of people who are, what we could call, alternative eaters.

For whatever reason, these folks prefer to consume food either through their nostrils or their anuses.

And imagine that sensitive individuals didn't want to exclude any of variety of preference. It's not fair that the anus eaters get all the attention, so we develop an inclusive acronym. We call anus eaters A's, and those who prefer nostril eating N's. If they enjoy both methods, we'll call them AN's.

Some like both mouth eating and anus eating, so we call them MA's. Those who like mouth eating and nostril eating, we'll call MN's. A few enjoy all three methods, so we call them Tri's or T. Those who are trying to figure out which methods they prefer, we will call I's for investigating. For all others, we'll indicate a plus sign. That leaves us with the acronym of ANANMAMNTI+.

And don't get me started on the people who like alternative excretion.

Why I write about human biodiversity

We HBD-ers are in an unfair situation.  I'll explain it with an analogy.  My wife is a beautiful woman, but let's imagine she's ugly as sin. And let's add she would make a good Jerry Springer guest.

Now, imagine we're at a dinner party, and all the attractive people there make her feel inadequate. So she gets upset with me and starts yelling about how I am never willing to pay for high-quality cosmetics, gym memberships, or expensive cosmetic surgery. I'm very embarrassed that she is making a scene in public, but she has just slandered me, so I proceed to explain to everyone that I have paid for attractive clothing, cosmetics, gym memberships, and plastic surgery, but the simple truth is that my wife is ugly, and nothing will change that. And how does the crowd react? Do they chide her for making false, nasty accusations in front of everyone? No, the crowd turns on me and thinks I'm an asshole for saying out loud that my wife is ugly.

People who report the facts about human diversity get the same kind of treatment. Liberals denounce whites publicly all the time for keeping minorities poor and dysfunctional. When we explain that the causes of minority problems are internal--for example, that they are due to lower intelligence--and that they don't have much to do with us, the crowd doesn't see the accusers as really nasty and unfair; instead, they turn on us as being insulting and abusive. And for the Left, being rude reveals that one is filled with hate.

I know that many HBD advocates preach truth first, middle, and last. I have another view.  If my wife were ugly, I wouldn't say it even though it's true. I would be diplomatic. I would only speak of it if I really needed to--perhaps if she were packing her bags to devote her life to becoming a Hollywood starlet. You speak unpleasant truths if you need to defend yourself, or it's the only way to help; if it's really necessary. And you don't go on about it.

The only reason I go on about HBD issues all the time is because the Left is destroying our society with its lying, irrational race obsession. I'm trying to help. I'll shut up when they do.

"If you can judge a wise man by the color of his skin, then, mister, you're a better man than I."

I often listen to classic rock radio stations. Once in awhile I hear "Livin' on the Edge" by Aerosmith, and think about why they inserted the following lyrics: "If you can judge a wise man by the color of his skin, then, mister, you're a better man than I." The song came out in 1993, so this was prior to the Bell Curve brouhaha. Rushton was publishing articles on the issue, but I doubt Rock-n-Rollers would know anything about that. Too busy snorting coke and screwing groupies. Maybe the band was simply responding to the stereotype that blacks are unintelligent.

So, are they right about choosing wise men? In one way, I would answer yes. All races are made up of mostly unwise people. If you have two random people, one black and one white, and you guess the white one is the wise one, you're likely to be wrong. Chances are, they're both ordinary.

On the other hand in choosing the white guy, you'd be less likely to be wrong. If we were to set the cutoff for wiseness at an IQ of 115, for example, there is a 16% chance you'd be right with the white guy, but you've only got a 2.5% probability with the black guy. In other words, you're 6.4 times more likely to guess right by betting on the white person.

The Left calls us racists, but the truth seems to be that they are the people who think in absolutes and categories, and we're the guys who didn't sleep through stats class and so know a little something about probability.

Which sex is more likely to reject evolution, and why?

Research indicates that men have more general knowledge than women, and--important for this blog--men know more about science. People like Richard Lynn see this as evidence that men have, on average, higher levels of general intelligence. The idea is that smart people seek out and absorb more information than others.

Perhaps this is relevant to the issue of belief in evolution. Understanding science better, are men more likely than women to accept the theory of evolution?

The General Social Survey asked participants if they believe that man descended from other species. In a sample of 6,375, 59.1% of men and 48.2% of women answered yes. That's roughly an 11 percentage point difference.

Now, let's see if superior knowledge of science helps explain the gender gap. We'll use logistic regression.  Here is the relationship between gender and acceptance of evolution

Belief in evolution--logistic regression coefficients

Male   .44***

***p < .001, two-tailed test

Men are significantly more likely to accept Darwin. Now let's see how much the coefficient shrinks when scores on a science quiz are added:

Male   .38***
Science Quiz   .42***

So some of the gender gap is due to superior male knowledge of science. How about religion? Women are more religious than men, and there is a tension between religious belief and acceptance of evolution.

Male   .14**
Science Quiz   .27**
Belief in God   -.62***
Church attendance   -.18***

**p < .01, two-tailed test

The gap closes even more: Women are less likely to accept evolution, in part, because they are more religious than men.

My last hypothesis goes beyond the sex difference in religiosity--perhaps men are more likely than women to accept ideas that are unpleasant. Most people are not thrilled to think that life has no objective meaning or purpose, or that they have a monkey for a grandfather.

The question was asked if the respondent agreed with this: "Life is only meaningful if you provide the meaning yourself."

Let's add this variable to the model:

Male  -.05
Science Quiz  .15
Belief in God   -.62***
Church attendance   -.14***
Meaning subjective    .32***

Gender and even science knowledge drop to non-significance when the meaning variable is added. The gender gap in belief in evolution seems to be explained by men's harsher, more secular worldview.

Which religious group is most likely to reject evolution?

The Left dislikes evangelicals as much as they dislike anybody, and one of the reasons they don't like them is because they tend to reject the theory of evolution--which is ironic since the Left rejects the implications of evolution for human nature. But what about Muslims? Don't they reject evolution as well? The Left is usually silent about Muslim fundamentalism.

How many American Muslims don't believe that humans descended from earlier species of animals? General Social Survey (GSS) respondents were asked this question. Here are the percent who answered no listed by religion (sample size = 6,353):

Percent who don't believe humans descended from animals

Muslims  65.6
Christians  65.5
Protestants  63.6
Catholics  36.2
Orthodox Christians  32.1
Jewish   20.1
No religion  19.8
Buddhists   4.5
Hindus   3.2

Muslims are at the top of the list. Compare them to Buddhists and Hindus. An enormous difference.

If fundamentalism is an impediment to a pro-science culture, why isn't it a problem when it's found among Muslims? For the Christian fundamentalists always you have with you, but inviting the growing Muslim world to move to the US is a choice.

UPDATE: My 12-year-old son informs me that Hindus naturally accept evolution because they believe in a God that is an elephant.

What is the profile of a scientifically knowledgeable person?

Scientific progress is crucial for the problems we humans face, but what types of people know science the best?

The General Social Survey (GSS) asked respondents 12 basic science questions. A random example is, does the father determine the sex of the child? One problem with the list of questions is that they are a bit too easy; the mean number correct is 9.5.

Shown below are OLS standardized coefficient for a number of factors I thought might predict scores on this science quiz (sample size = 203):

Standardized OLS regression coefficients

Male  .09
Age   .01
Black   -.19**
Other race   .00
Years of education   .32***
Believe in God   -.19**
Church attendance   -.07
Political conservatism  -.06

**p < .01, ***p < .001, two-tail test

According to the results, basic scientific knowledge is predicted significantly by being white; having more education; and being skeptical about the existence of God. The other variables are not predictive.

But you might be thinking, hey, this is a HBD blog--where's IQ?  Well, I wanted to throw it in last to see how it changes things:

Standardized OLS regression coefficients--IQ added to model

IQ   .35***
Male  .20
Age   -.10
Black   .08
Other race   .04
Years of education   .08
Believe in God   -.33**
Church attendance   -.04
Political conservatism   -.01

**p < .01, ***p < .001, two-tail test


Education and being black drop to non-significance when IQ is added to the equation.  In other words, the reason why more education people know more science is because they are smarter, not because they were exposed to more information than less educated people, and blacks score lower because they are, on average, less intelligent.

By contrast, skepticism about God strongly predicts scientific knowledge even after taking IQ into account. This suggests that, at least under current conditions, skeptics take to science more than believers, even after controlling for differences in IQ.

UPDATE:  I discovered that fewer people were asked the last science question, so I dropped it to get the sample size up to 1,039--much bigger. Here are results for the final model:

Standardized OLS regression coefficients--IQ added to model

IQ   .29***
Male  .14**
Age   -.02
Black   -.12***
Other race   -.03
Years of education   .22***
Believe in God   -.16***
Church attendance   -.12***
Political conservatism   -.07*

*p < .05, **p < .01, ***p < .001, two-tail test

We now have the statistical power to see smaller effects.  IQ still dominates the model, but now we see that the following traits predict knowledge: male, white, more education, disbelief, not attending church, and liberal political orientation.

After IQ, education is most important, followed by skepticism, gender, race, attendance, and political orientation. Keep in mind that these factors matter even after taking IQ into account. For example, and man whose IQ is the same as a woman's is likely to know more science than she does.

Race differences in drug dealing

What are the racial differences for drug sales? Arrest data for 2018 were provided by the FBI:

Percent of Arrests for Marijuana Manufacture/Sales
Black   44
White   52
Asian     2
Native American   1

According to the Census, blacks were 13% of Americans in 2018. The Census lumps Hispanics and whites together: They were 77% of Americans in 2018.

Based on these numbers, the black rate of marijuana sales is 5 times that of whites/Hispanics.


Percent Arrests for Opium or Cocaine Manufacture/Sales
Black   47
White   51
Asian     1
Native American   1

Using the same calculation, the black rate of opium/cocaine sales is 5 1/2 that of whites/Hispanics.


Percent Arrests for Other Dangerous Nonnarcotic Drug Sales
Black   19
White   78  
Asian     1
Native American   1<1 font="">

Compared to whites/Hispanics, the rate of other dangerous drug sales by blacks is almost 1 1/2 times higher.


Percent Arrests for Synthetic Narcotic Sales
Black   21
White   78  
Asian     1<1 font="">
Native American    1

Finally, the black rate for synthetic narcotic sales is 1.6 times that of whites/Hispanics.

Blacks surpass whites in all types of sales, especially opium, cocaine, and marijuana. Of course, with Asians being only 6% of the country, comparing them with blacks would reveal much larger differences.

Have white liberals veered left in recent years because they've lost their moderates?











Zach Goldberg has documented how white liberals have done a sharp left turn on racial issues over the past few years, a phenomenon that's called the "Great Awokening." I wondered how much of this is due to more moderate white liberals shifting to a moderate or conservative self-label.

The graph above shows trends in political self-identification among whites, according to General Social Survey (GSS). Let's summarize the trends over the past, say, decade by creating a list:

2010-2108 Trends in Political Self-Identification

1. More extreme liberals
2. More extreme conservatives
3. Fewer moderates
4. Fewer slightly liberal
5. Similar number of liberals
6. Similar number of conservatives
7. Similar number of slightly conservative

Changes have not been dramatic, but overall the extremes have grown at the expense of the middle. A small number of slight liberals have moved, but it is not clear to where. Let's look at a chart where all conservatives are lumped together and the same for all liberals.











First, we see the same shrinkage among moderates. Since 2010, conservatives ticked up a bit as did liberals. So, bottom line, it looks at though liberals really haven't gotten more radicalized because they've lost moderates. Their size is similar to a decade ago; they have simply veered left on racial issues.

Does the racial gap in fertility shrink in low-cost areas?

When it comes to having kids, it's possible that whites are more sensitive to the cost of living than are blacks or Hispanics. Perhaps the racial differences in fertility are smaller in inexpensive regions. Using General Social Survey (GSS) data, I calculated the mean number of offspring for women ages 40-59 during the years 2010-18.  The GSS records the region of the country in which the respondent lives. There are nine regions: I decided to compare the Pacific (west coast) and West South Central (TX, LA, OK, AR) regions since the former is expensive while the latter is more affordable.


Mean number of offspring
Pacific
Hispanic    2.92
Black         2.08
White         1.75

West South Central 
Hispanic    2.55
Black         2.27
White         2.11

As expected, Hispanic fertility is highest in both regions, while whites are on the bottom. While black and white women have more kids in the WSC region, Hispanic women in the Pacific have bigger families than Hispanics in the WSC, contrary to expectations.

Look at how the racial gap in the WSC is smaller than in the Pacific region. The Hispanic-white gap in the former is .44 kids, while it is 1.17 in the latter. Comparatively speaking, whites benefit from living in low-cost regions.

Do whites benefit when they move from a high-cost to an inexpensive region? The best I could do to answer this question with GSS data was to use a question about where you lived at age 16.  I extended the time span to 2000-2018 to get a large enough sample size and focused on a move from the Pacific to the Mountain region since it was the most common expensive-to-cheap move.

Mean number of offspring--whites

Pacific to Mountain States   2.17
Stayed in Pacific                  1.71

You can see that whites who lived in the Pacific region at age 16 but subsequently moved to the Mountain States averaged more kids than those who did not move out of the region. The move to cheaper regions seems to help fertility.

Are religious people more ethnocentric?

Does loyalty to one group you belong to predict loyalty to other groups?  I suspect that religious people are also more likely to value their ethnicity.  The General Social Survey (GSS) asked people how important their ethnicity is to them with answers ranging from unimportant (1) to very important (4). 

I categorized people as not religious if they attend religious services no more than once per year. All others I lumped into the religious group. The means for thinking ethnicity is important to you are listed below--the means for the religious in parentheses, the means for the irreligious without parentheses (sample size = 2,110)

"My ethnicity is important to me"-- means

American Indian  3.50  (3.50)
Black  3.47  (3.53)
Chinese  3.40  (3.75)
Mexican  3.22  (3.47)
Puerto Rican  3.19  (3.60)
Italian  2.85  (2.72)
Jewish  2.76  (3.26)

Total  Sample  2.60  (2.84)

Scottish  2.55  (2.44)
Irish  2.45  (2.60)
German  2.35  (2.50)
Swedish  2.29  (2.67)
Russian  2.25  (2.95)
English/Welsh  2.21 (2.50)
Polish  2.13  (2.67)

For most of the ethnic groups, ethnocentrism is higher for the religious group. The differences are generally not large but look, for example, at how religious Swedes are almost as ethnocentric as secular Jews.

The difference at the extremes is large: the gap between religious Chinese Americans on the high end and the irreligious Poles on the bottom is well over one standard deviation. The typical Chinese person who goes to church says his ethnicity is 'moderately' or 'very important.' Compare that to the average Polish American who is not religious: he says his ethnicity is 'slightly important.'

Which racial groups think science does more harm than good?

While I am not a science worshipper, I do think it offers answers to many of our problems, at least eventually. Unfortunately, science doesn't happen magically. It requires very talented people and a society with the means and culture to support scientific work. 

Americans vary a great deal in their attitudes toward science. The General Social Survey (GSS) asked participants the following: "How much do you agree or disagree that, overall, modern science does more harm than good?" Answers ranged from "strongly agree" (1) to "strongly disagree" (5), so higher scores indicate greater belief in science. Here are the means by ethnic group (sample size = 6,226; I included religious affiliation as well):


Mean belief that science is good

Finnish  4.16
Jewish  4.08
Russian  3.99
Japanese  3.95
Lithuanian  3.87
Hungarian  3.86  
Buddhist  3.84
Austrian  3.83
Greek  3.83
English/Welsh  3.82
Danish  3.81
Scottish  3.81
Swedish  3.80
Norwegian  3.78
No religion 3.78
Italian  3.76
Irish  3.72
French  3.71
Hindu  3.67
Orthodox Christian  3.65
German  3.64
Swiss  3.64
Asian Indian  3.61
Dutch  3.61
Spanish  3.61

Total Sample  3.60

Muslim  3.60
Catholic  3.59
Chinese  3.53
Arab  3.50
Immigrants  3.37
Mexican  3.26
Black  3.20
American Indian  3.00
West Indian  2.82

The pattern is clear: whites groups have much more faith in science than non-whites. Japanese Americans, a smart, successful group, are an exception.  Among whites, Finns and Eastern/Central Europeans tend to be the most positive about science. Among religions, Jews come out on top. The gap between Finns at number one and West Indians on the bottom is well over one standard deviation--a very large difference. 

I included immigrants as a group: they are toward the bottom of the list. If we want to have a country fully in support of science, our immigration trends are counterproductive. 

It looks like some of the explanation for the pattern we see is IQ, but I wouldn't be surprised if non-whites have a tendency to see science as an evil white thing. Think Tuskegee. It's BS, but this might help explain negative attitudes.

Are the Scots-Irish leading the way toward race consciousness?

I'm thinking that one way to measure an ethnicity's meaningfulness as a group is the extent to which they vote as a bloc. For example, why do blacks, whether wealthy or poor, urban or rural, religious or not, vote overwhelmingly Democratic? Because race is very important for them, and the vast majority see the Democratic party as best serving their interests.

The numbers shown below were calculated like this: 1) Look to see whether more of the ethnic group voted for Hillary or Trump; 2) subtract from that number the percent of all Americans who voted for that candidate; and 3) give a positive sign for those skewed toward Hillary and a negative sign for those skewed toward Trump. I included major racial and ethnic groups, and religions as well since they can also be cohesive groups (General Social Survey, sample size = 1,128).

Voting bloc index

Asian  46.5
White Southern Baptists  -45.0
White--American only  -43.3
Black   41.3
Puerto Ricans  32.2
Protestant Irish  -25.2
Scottish  -23.1
Southern Baptist  -22.0
Jewish   18.9
Mexican  17.5
Catholic Irish  -16.2
German  -14.1
Italian  -10.9
Whites  -9.9
Scandanavian  -9.4
English/Welsh   -9.2
American Indian  8.4
Slavic (non-Jewish)  -8.4
Episcopalian  -7.3
Catholic  -3.5
United Methodist   -2.9

Not surprisingly, non-whites tend to be the most ethnocentric. Asians include people whose families came from China, Japan, and India--they score even higher than blacks.

Hispanics and Jews are in the mid-range, but the striking numbers are for: 1) white Southern Baptists; 2) whites who say their ethnicity is American--Scots-Irish are likely to say this; 3) the Protestant Irish; and 4) Scots. The numbers for white Southern Baptists and for "Americans" are second and third highest on the list (!) and the scores for the other two groups are higher than that of either Jews or Mexicans.

I interpret this as an inchoate sense of identity. For other white groups or religious denominations, there appears to be weaker group cohesiveness. It's higher than zero for all groups, but the Scots-Irish seem to be leading the way on a path toward race consciousness.

Which is a stronger predictor of belief in God: lower IQ or feeling like you don't have control over your life?

With the rise of militant, celebrity atheists, quite a bit of attention has been devoted to data that show that atheists tend to be smarter than theists.  Race realists are likely to rely on IQ to explain the greater religiosity of blacks and Hispanics.

I can think of another factor that might help explain these patterns: having a sense of control over one's fate, called locus of control by psychologists. As a religious person myself, I see that some people get interested in religion when they feel helpless. They turn to God when there is trouble they can't seem to handle. Many of my irreligious colleagues seem very in charge of their lives; they've got it all under control.

I've also read research that indicates that poor minorities tend to feel that they do not control their life outcomes. This is called an external locus of control. Maybe this sense of vulnerability explains their stronger belief in God.

The General Social Survey asked respondents, "Do you agree or disagree with the following: We each make our own fate." Answers ranged from "strongly agree" (1) to "strongly disagree" (5).

They were also asked about their confidence in the existence of God with responses ranging from "don't believe" (1) to "know God really exists and have no doubts about it" (6). As a first step, let's use OLS regression analysis to see if race is linked to belief in God and locus of control (sample size = 741):

Confidence in the existence of God (standardized OLS coefficients)
Black   .13***

Hispanics did not differ from whites significantly in belief in God, so we'll focus on blacks. They have greater confidence in God's existence.


External locus of control
Black   .06**

Compared to non-blacks, blacks are more likely to think they do not make their own fate. Now let's look at race, IQ, and belief.


Confidence in the existence of God
IQ   -.16***

As expected, we see IQ is associated with more doubting, but the correlation is weak.


Confidence in the existence of God
Black   .10***
IQ   -.14***

Recall how the black estimate for belief was .13 when only race was entered into the model. We see that when IQ is added, the black coefficient shrinks but does not disappear. This indicates that some of the greater belief by blacks is explained in terms of lower IQ, but much of the gap remains unexplained. Let's add locus of control:

Confidence in the existence of God
Black   .00
IQ   -.14***
External locus of control  .18***

When external locus of control is added, the race coefficient drops to zero. Much of the reason why blacks are more likely to believe in God is because of a sense of helplessness.  And when it comes to predicting belief, an external locus of control is more powerful than IQ.

This is a reminder than while HBD-ers are right to focus on intelligence, there are other consequential traits. Moreover, there is evidence that locus of control, like practically all psychological traits, is genetically influenced. According to this twin study, about 1/3 of the variation of a sense of control over your own life is due to genes.

Who has the higher rate of bias crimes against Jews--whites or blacks?

The mainstream Media finds every opportunity to push the story that hate comes from the Right. Even when Black Hebrew Israelites kill three Jews in a kosher market in Jersey City, it's somehow caused by MAGA-wearing Trump supporters.

Unlike the Media, this blog relies on data. The FBI puts out annual hate crime statistics--2018 is the most recent.

There were 228 anti-Jewish incidents in which the race of a single-race offender is known. In 179 or 79% incidents, the offender was white or Hispanic. (The US government tends to lump us together.) Blacks committed 41 or 18% of the anti-Jewish crimes. The Census tells us that 77% of US residents are white (if Hispanics are included) while blacks are 13% of the population. Based on these numbers, the rate of anti-Jewish incidents for blacks is 1.4 times that of whites. Blacks--not famous for being right-wingers--are significantly more likely to commit bias crimes against Jews.

While I'm at it, look at the total numbers. There were 228 incidents--896 if we include all incidents in 2018, even those where the race of the perpetrator is unknown. According to the Census, the US has 6.9 million Jews, so the annual rate of anti-Semitic incidents is 12.9 per 100,000. To give some context, the annual US homicide rate hovers around 5 per 100,000 total population, so these incidents are not much more common than homicide--a very rare type of crime.

Moreover, of the 372 incidents against Jews where the type of crime was recorded, the most common category by far is intimidation--243 incidents or 65% of all incidents. There were only 24 aggravated assaults and 11 murders. While any attack is serious, the US has roughly 15,000 murders per year. Hate crimes are a minuscule part of the problem.

UPDATE: The hate crime laws were written with evil whites in mind--our elites assume the worst of whites and the best of non-whites--so I suspect that prosecutors are prone to interpret incidents by whites as hate, while incidents committed by blacks are likely to be seen as common crimes.

Among the greatest movie directors, will you find more women or gay men?

Why have almost all of the greatest movie directors been men?  Don't women like movies just as much as men?

Feminists, of course, would blame the patriarchy: Men have mysteriously gotten control of the world and will not let the helpless women do fun things like make movies.

But if discrimination has been so pervasive in the film industry, why in the world have we seen so many top homosexual directors?  I'm not convinced that men before the 1970s were that dead set against women occupying important positions. Just the other night, I watched an old film titled, "Kansas City Confidential" (1952), and the lead female was studying to take the bar, and none of the male characters cared in the least.

Now, imagine the same story, but the romantic interest is a gay man preparing for the bar.  Do we see movies like that for most of the 20th century?  Hell no. Off the top of my head, I know that Clark Gable did not want George Cukor--known to be a homosexual--to direct "Gone With the Wind" and was influential in having him replaced by Victor Fleming. While there were plenty of homosexuals in Hollywood, people loathed it.  No matter--gay men thrived in Hollywood and Europe as well. Perhaps you doubt this.

I went to the website "They Shoot Movies, Don't They? and looked at their list of the top 250 directors of all time. The ranking is based on such factors as voting by directors and critics. I categorized a director as gay or bisexual if Wikipedia indicated they were. I put together the following list:

Gay Directors (from top 250)

Pedro Almodóvar
Lindsay Anderson
Kenneth Anger
Marcel Carné
Jean Cocteau
George Cukor
Terence Davies
Jacques Demy
Rainer Werner Fassbinder (bisexual)
Robert Hamer
Todd Haynes
Vincente Minnelli (bisexual)
F. W. Murnau
Pier Paolo Pasolini
John Schlesinger
Gus Van Sant
Luchino Visconti
Lana Wachowski (male-to-female transgender)
Lilly Wachowski (male-to-female transgender)
James Whale

I included the transgender Wachowski brothers since transgenders should face discrimination, if it is indeed such a profound problem.

That's 20 gay, bisexual, or transgender directors or 8% of the total. Keep in mind that sexual minorities are less than 8% of men, so they are over-represented among the greatest directors.

How about women?

Female Directors (from top 250)

Kathryn Bigelow
Jane Campion
Claire Denis
Danièle Huillet (co-director with her husband Jean-Marie Straub)
Leni Riefenstahl
Agnes Varda

That's 6 or 2.4% of the total, and let's not forget that if women we're punching at their weight, they would be half of the best directors. Their numbers are abysmal.

You might counter that discrimination was intense through 1970, but things have changed and that is why we see that all top women are from the past few decades. Again, I would argue that if bias was intense prior to 1970 for women, it should be even more so for gay men--a hated minority if I've ever seen one--yet easily half of them worked prior to 1970.

The facts suggest that men are simply better at making movies. If a studio exec wanted to make the best "Little Women" possible in 1933, he needed to hire George Cukor and not give a damn about his "quirks." If a woman would have done it better, I submit that the studio execs would have swallowed hard and given her the job, even in 1933. A lot of money was on the line.

What qualities do men possess that give them such an advantage? Well, I'm no expert on directing, but I know that these are incredibly talented people at the highest percentiles of all relevant traits. These would include: intelligence, leadership, charisma, confidence, decisiveness, technical mastery, visual skills, writing skills (plot, character, dialogue, mood, humor), effective criticism, and ability to deal calmly through all the drama that comes with managing creative types. There is evidence that at the highest levels, men surpass women on these traits. And, by the way, the traits are all rooted in biology.

Which is more important for education attainment: your IQ or your dad's social class?

While I am convinced that genes are a strong influence over people's lives and that the impact of the parenting is wildly exaggerated, I am open to data on these questions--I call myself Inductivist after all.

This meta-analysis of 15 heritability studies conducted in a variety of countries and decades found that shared environment explained a sizable portion of the variation in educational attainment; to be specific, almost 40%. That's a much higher average than typically seen in heritability studies.  The authors also found that shared environment was stronger for women and for people studied prior to 1950, suggesting that factors like family financial support have mattered more for women and for people in the past.

We can use General Social Survey data to answer a related question: Is educational attainment due to IQ or dad's socioeconomic status (SES)?  First, let's see how strongly each predicts years of education completed (I limited the analysis to data from 2010-2018, sample size = 947):

Standardized OLS regression coefficients

Model with Father's SES only
Father's SES  .37***

Model with Child's IQ only
Child's IQ   .45***

IQ is the stronger of the two predictors, but nurturists might argue that father's SES causes child's IQ which, in turn, determines educational attainment. We can address this question by entering both into the model as predictors. By doing so, we can see if the link between IQ and education shrinks to nothing once we've accounted for the influence of dad's SES.

Model with Father's SES and Child's IQ
Father's SES   .24***
Child's IQ  .44***

When both predictors are entered into the same equation, the father's SES/child education correlation is reduced, but the impact of IQ on schooling is basically unaffected. We can interpret these findings this way: How far you go in school is influenced by your dad's social class (consistent with the meta-analysis), but your own IQ is much more important. The strong correlation between IQ and schooling is not at all due to the tendency of high-status men to both have smart kids and to help them continue in school.

By contrast, part of the reason why father's SES is linked to child's educational level is because high status men have smart kids, and smart people naturally go further educationally. Once you take into account the pathway from dad's status through offspring IQ to completed education, the link between dad's class and child's educational attainment is weakened substantially. In other words, factors beyond the kid's IQ, like family financial support, are not as strong important as they look.

I looked at females only and got the standardized coefficients of .23 (dad's SES) and .43 (child's IQ), so the process works the same for girls as well as boys.

I also looked at mom's SES, and I found very similar results.

***p < .001, two-tailed test

UPDATE: The strong correlation between IQ and years of education reminds me of Taleb's anti-IQ argument: IQ-type tests get you into college, so there is a built-in correlation. There might be a link between test score and which college you get into, but there is no such circularity with how many years of school you complete. Regardless of your test score, you can get admitted to some college.
