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.

New research on testosterone and behavior

A retired researcher friend asked for my help. He has been linking male sex hormones to behavior for more than three decades. Since he is retired, he has no access to students to volunteer as research participants. I can't help him because there is no way the IRB committee at my university will approve this study.  He needs volunteers to complete this 5 minute survey. Please help if you can, and invite others. We need the broadest sample we can get. Warning: you will need to measure a body part!  https://www.surveymonkey.com/r/NKBRYYR

UPDATE: Of course, this study is very exploratory. He wants to see if it looks promising.

Addiction among American Indians

I ran across a new study reviewing the research on race and addiction. The authors find that: 
In these studies, both past year and lifetime rates of alcohol, nicotine, and drug use disorders were consistently higher in Native Americans and lower in Asians,with Blacks, Hispanics, and Whites in between. 
It looks like any theory of American Indians (AIs) that limits itself to alcohol (e.g., the notion that AIs have not been exposed to it long enough to adapt to it) is missing part of the story. Addiction to drugs in general tends to be more common in this population.

Also--the stark differences between Northest Asians and Natives--addiction differences being only one illustrative trait--show how quickly significant genetic change can occur (the differences surely can't be 100% due to environment). It's not like these groups split 100k years ago.
