Is "Latino Lover" a thing?

I was watching "Being the Ricardos" last night, and one of the film's themes was Desi Arnaz' infidelities. It made me wonder if there is any truth to the stereotype of the Latin lover. 

The General Social Survey asked married men if they had ever cheated on their spouse. Here are the percentages (N = 4,243):

Percent of married men who have cheated

Non-Hispanic black  25.2
Black Hispanic  20.0
White Hispanic  16.9
Non-Hispanic white 16.3
Hispanic--other race  15.0
Non-Hispanic--other race  13.9

I calculated percentages for each race because I know it is relevant for infidelity. There is evidence here that black men cheat more than other groups, but rates are not high for Hispanics.

The 2021 General Social Survey: How many transgenders?

 The 2021 General Social Survey is out. Respondents were asked their gender. Here are the results:

I am interested in the transgender issue, but let's take notice of an important GSS fact: It is heavily skewed toward women, so you need to take this into account when looking at results that differ by gender. For example, in 2021 8.4% of men do not believe in God, but only 5.1% of women believe the same way, so an excess of women in the sample will skew the results for the total sample. 

But let's focus on transgenders: They are 0.3% of the sample. This is 3 per 1,000, folks, not radically different from what I was taught in college many years ago. The figure is also similar to that of the California study that reported .35% of the state is transgender. 

You do see 0.4% who don't fit into the other boxes, so there is a small percentage of confused people out there. 

The GSS is a sample of adults (18+), so the apparent growth in transgenderism is occurring among teens.

What percent of Americans under 40 are Christians?

 A follower on Twitter indicated that he is not Christian and wondered what percent of Americans under 40 are. Well, you know I'm a sucker for that kind of question. The General Social Survey asked people about their religious affiliation in 2018--the latest published data. Here are the results: 

If we add up the numbers for Christians, we get 59%, and it's probably closer to 60% since I did not include "Other", which, for example, probably includes quite a few Mormons, who consider themselves Christians and restorationists, not Protestants. If we we create a table with adults 40 and over we get this:

Added up, 78.2% of older Americans are Christians, so the percentage among young people is dramatically lower. It's not a coincidence that many young people also favor socialism.

Is skin tone correlated with job prestige?

The General Social Survey rated the skin darkness of a sample of black Americans, ranging from "very dark brown" to "very light brown." Biologically oriented researchers might see the question as a rough measure of the percentage of European ancestry, while sociologists would see it as a measure of discrimination--lighter-skinned blacks getting better treatment. Respondents were also given a job prestige score that ranges from 16 to 80--16 is a shoeshine and 80 is a physician. Here are the job prestige means listed by skin tone:

You can see that average job prestige tends to rise with lighter skin. The mean for blacks with "very light brown" skin is roughly two-thirds of a standard deviation higher than the mean for "very dark skin" blacks. 

The pattern can be interpreted in at least two ways: 1) genetic--blacks with more European ancestry tend to rise in the status hierarchy much more than African blacks, or 2) sociological--whites discriminate more against darker blacks, and perhaps light-skinned blacks have white (privileged) relatives who gave them advantages. 

For several reasons, I'm inclined toward the genetic explanation. For one, my experience is that when a white person is interacting with a black person, his thought is, "I'm talking with a black person," not, "I'm talking with a light-skinned black person." For another, how do those Nigerian immigrants do so well in the US when their skin tends to be so dark? The sociologist would predict severe discrimination. The biologist would argue that African immigrants are a select group of Africans--above average in IQ and drive--and this overwhelms any bias they might experience.

Do blacks and whites who grow up equally wealthy end up with the same mean IQ?

Some people argue that mean IQs for whites and blacks differ because blacks tend to come from poorer families. A black kid raised with resources equal to a white kid will have the same IQ. Is this the case? 

Using data from the General Social Survey, I calculated mean IQ for blacks, whites, and others for several ranges of father's socioeconomic index (SES): 1-2 standard deviations (sd) below average, 1 sd below average to average, average to 1 sd above average, 1-2 sds above average, and over 2 sds. The sample size is 12,016 (immigrants were excluded). Here's a graph that summarizes the results: 

Blacks and whites raised at the same SES level do not have the same mean IQs. The higher white average ranges from about 7 points among the poorest group to more than 10 points among the wealthiest group. By the way, other non-whites--mostly Hispanics--are closer to blacks than whites.

Who is more likely to be murdered by a black offender: a white or an Asian?

 Wilfred Reilly (@wil_da_beast630) has a discussion going on at Twitter about which race currently faces the most "systemic racism." Some people are assuming that Asians are victimized by blacks more than whites are. Two sources of data are not very helpful here: hate crimes and victimization data from the National Crime Victimization Survey. Hate crimes are a tiny drop in the bucket of all violence, and you don't see NCVS tables with Asian victims by race of offender. (Let me know if I've missed them.) Victim data in general indicates that Asians face low levels of victimization, which makes sense because most crime is intra-racial, and Asians have very low rates of criminal offending. 

Perhaps homicide data is the best way to go here. I looked at expanded FBI homicide data and the Census to calculate rates for being murdered by a black person for two groups: 1) Whites/Hispanics, and 2) Asians/ Native Americans/Pacific Islanders. I'm afraid the FBI lumps people together that way. The rate for group 1 is 2.30 murders per 1 million population. For group 2, it's 1.44 murders per million. According to FBI data, blacks pose more of a threat to whites and Hispanics than Asians plus.

Which low IQ groups have low arrest rates?

DGo (@Go321) on Twitter wondered which lower IQ groups still manage to be well-behaved as groups. Criminality is a decent measure of behavior, so I looked at General Social Survey data to see which groups with low average IQs also have lower than average arrest rates: 

The percent arrested for the whole country is 12.7%. The groups listed above with an arrest rate lower than that are: Filipinos, West Indians, and Non-Spanish West Indians. And let me add that these three groups have IQ means that are not very low: 96.7, 98.8, and 95.9, respectively. 

Most lower-IQ groups have high arrest rates, as expected.

UPDATE: After checking, I see that Arabs do not have a low mean IQ: it's 102.
