Trendy trends in identifying as a sexual minority

This Gallup poll is from a survey of over 300k Americans in 2017. You can see a dramatic uptick from 5.8% to 8.2% among Millennials identifying as LGBT over the past 5 years. Kinda dumb to lump the sexes: for all generations, 3.9% of men and 5.1% of women now identify as a sexual minority (table not shown). This is the first time I've seen women with higher numbers than men. Trendy trends on display.

I learned as an undergraduate in social psychology that "prejudice" refers to judging people before knowing the facts. I was told that it was bad to do that. Now young people are taught that it's bad to judge AFTER getting the facts; for example, making a judgment about a group after looking at data presented at this blog. I guess we need a new word for this transgression. "Postjudice" seems a bit awkward.

Group differences in gonorrhea

This new study examines US patterns of gonorrhea from 2000 to 2015. In 2015, there were almost 400,000 cases reported. Over the 16-year study period, there were 21 million cases. There are two distinct epidemics currently occurring in the US: one among young black heterosexuals, and one among men who have sex with other men (MSM). (Can we attach some meaning to the fact that MSM also stands for 'mainstream media'?)

Hispanics have an infection rate that is 1.8 times higher than among whites. For blacks, it's 9.6 times higher than for whites. Even though MSM's are a tiny sliver of American men, they account for 67% of all infections in males.

The authors claim that one's number of sex partners is an inadequate explanation for what we see. I'm sure there are other factors (e.g., differences in condom use), but gonorrhea rates have got to be an alternative to measuring sexual behavior with self-reports. Surveys don't indicate such enormous group differences, but the pattern of disease suggests that compared to straight white people, blacks and MSM's get around.

Oh the crushing power of Patriarchy!

Here's a table from a new AEI study that shows the US 2016 Bachelor's degrees by major and gender. My nieces and the female teens at my church were all encouraged to go into a STEM field, but I guess some sinister, mysterious force is hypnotizing girls to major in Family Sciences. Notice how almost 300,000 more girls than guys graduated with a degree. Oh how the Patriarchy is CRUSHING these girls!

UPDATE: Okay, I'll confess--I basically majored in Family Sociology. How low-T can you get!

Black-white differences in glaucoma

Glaucoma is a progressive condition caused by a combination of genetic and environmental factors and is the leading cause of irreversible blindness worldwide. Primary open-angle glaucoma (POAG) is the most common form of glaucoma and is often associated with elevated intraocular pressure (IOP).

The additive heritability of POAG ranges from 24 to 42%. This new study analyzes data on 4,986 POAG cases and 58,426 controls from 4 race/ethnicity groups. The authors found 24 loci linked to POAG.

The authors found more than double the prevalence of POAG among African-Americans compared to whites--16.1% vs. 7.4%. (The prevalence for East Asians was 9.9%; for Hispanics, it was 7.9%). The figures below shows the relationship between genetic ancestry and POAG. 

Hold it--I thought, as Jonathan Marks instructs us, that race is a cultural and political phenomenon, not a biological one?

Teens who use marijuana around the time of sex are less likely to wear a condom

In a new meta-analysis of eleven studies, teens who use marijuana around the time of sex were only 62% as likely to use a condom as those not using the drug. One more reason why pot is dumb.

Are conservatives happier than liberals like Rush says?

You constantly hear Rush Limbaugh claiming that liberals are miserable people. Is this true?

The  General Social Survey asked 3,322 people: 1) who they voted for in 2012 and 2) how happy they are, generally speaking. Here's the breakdown:

Percent Very Happy
Obama Voters  27.9%
Romney Voters  36.8%

Percent Not Too Happy
Obama Voters  13.9%
Romney Voters  9.3%

Myself, I'm sad I voted for Romney. But it looks like Rush has a point even if he exaggerates a bit. Personality traits might explain the difference: Liberals are more prone to negative emotions, they are less conscientious (self-disciplined), and both of these predict less life satisfaction. 

My bet is that if I looked at social factors, I'd find that conservatives are more religious and more likely to be married, and both predict happiness (believe it or not). Maybe in a later post.

Are immigrants superior to Americans?

David Brooks in a NYT's piece claims that immigrants are superior to Americans--they "outhustle" us. Is this true?

The General Social Survey (GSS) asks non-retired participants about their work status. Let's use full-time employment status as our measure of "hustlers." According to the data, 61.3% of white and 53.4% of black Americans work full-time. For immigrants of all races, it's 56.3%.

Where exactly is the mind-blowing hustle Brooks is referring to? I think Brooks is doing what liberals often do: take a black reality that's troubling and then pretend it's whites who have the problem. For example, private gun ownership is portrayed as scary, and images of white rednecks are drummed up, but progressives are actually afraid of blacks having firearms.

People like Brooks have an instinctive dislike of ordinary whites because this group is seen as actually being capable of organized nastiness, while brown people are not. He is wrong about this. I'm no historian, but I do seem to remember something about whites not doing very well in Haiti around 1791.
