Useless loud cheap (mis)targeted ads

There’s a multi-bazillion industry devoted to making me buy things. They have followed me through all of my days and tracked my every thought.

Searching for plum blossoms in the snow

(Xu Daoning, c. 1000 AD, Freer Gallery)

So you’d think they’d know I’m in the market for a vacuum cleaner, right?

Noooo.

I haven’t bought one in dog’s years. I don’t read articles about vacuums for fun. All they know about is the last thing I searched for, not what I need.

Well, I’m not a total newbie. I’ve been around computers since the days of punch cards. I’ve heard of Google. All I have to do is search, right? I want a machine in the neighborhood of $200, outrageously good at picking up pet hair, good at corners, and that doesn’t spew the dust right back out.

The search understands I want a vacuum cleaner, but that’s as far as it goes. To get what I want, I can spend hours — nay, days — of my life plowing through useless store websites full of obnoxiously happy beautiful people who find everything with one push of a button. Or I can dig through pages of search results, trying to find reviews that aren’t ads in disguise.

I am not a patient person. The first time, I put off the purchase after an hour or so. The second time it might have been two hours. Then I gave up for a couple of years. That’s what happens when there’s a massive selling industry in my face with everything I don’t want. You’d think they’d have an easier time hitting a great big bullseye like a customer looking to buy a product. By the time I finally bought a vacuum cleaner, they could have sold me a second one if the hucksters who’ve taken over the web instead made it easy for me to find what I want.

Inside a mind too safe to care

“I understand [Obama] wants to fight terrorism, but send in robots, drones. Don’t send in our troops. Our men and women are dying for what?”

Seen here, quoting someone in the USA regarding Obama’s moves in Iraq.

Translated: I don’t care who dies or how they die so long as it’s nobody I know.

Further translation: I know nothing about warfare and think it’s like a video game where drones work on their own and problems get solved by smashing them.

And also too: I don’t have to care or make sense because nothing’s gonna change my world.

Arrogance made a dog’s breakfast out of the Middle East. Now it’s their problem. Right?

My taxes pay for this shit. I’m sorry. I’m sorry, I’m sorry, I’m sorry. Which does no good at all. Dear God, what a mess, what a crime, what an atrocity.

Teachers: the floggings will continue until morale improves

California’s teacher tenure law ruled unconstitutional.

Los Angeles County superior court judge Rolf Treu … said the current situation discriminates against minority and low-income students in placing ineffective teachers in their schools. “Plaintiffs claim that the challenged statutes result in grossly ineffective teachers obtaining and retaining permanent employment, and that these teachers are disproportionately situated in schools serving predominantly low-income and minority students,” the decision said.

The Teacher’s apple

That’s right. Underfund the schools. Underpay teachers. When they buy school supplies out of their own money, don’t be amazed. Ask why they’re not donating more. Tell them how to do their jobs. When the students learn even less, get mad at the teachers and tell them they’re doing their jobs all wrong. When anybody with any brains stops even trying to fight their way through all this garbage to become a teacher, wonder why there aren’t any good teachers.

Oh, and remove the last shred of job security. That’s sure to attract good people to bad schools. What could possibly go wrong?

Update 2014-06-15. Turns out I was channeling Diane Ravitch’s more sober and well-sourced article, June 13th: Making Schools Poorer.

Gay gene: it’s not what you think –part 2

Since the mid-1990s I’ve been thinking about a pattern that seems significant. There are a whole range of what you could collectively call “brain organization traits” that are commoner in males than females. Left handedness, lower or later verbal development sometimes paired with higher math ability, slower social development through the whole spectrum to Asperger’s and autism, homosexuality, and no doubt I’m missing a few. The difference isn’t always large, for instance left handedness shows only a 1.23:1 male:female preponderance, but it is statistically significant. Asperger’s, on the other hand, is diagnosed at about 4:1 males:females. Homosexuality approximately 3:2, dyslexia, about 3:1.

That is odd. The ratios are unlike, say, color-blindness which is an X-linked trait and hence necessarily more prevalent in males. (Just some bio background for those who might want it: men have one X, women have two. Therefore women have two copies of any X-linked gene and a much higher chance that any given genetic information on one X can be masked by the other copy. That’s why X-linked conditions mostly show up in men.)

So it has to be some unstraightforward factor that affects males more than females. No post-natal environmental factor has ever been reliably identified for any of those traits. The traits all have to do with neurological pathways. It seemed logical that the prenatal environment which affects brain development was the place to look. Sex hormones like estradiol and testosterone play critical roles in brain development. And there’s one very obvious prenatal difference between males and females: all mothers are female, so female fetuses are likelier to have a hormonal environment aligned with their own than male ones.

In 2006 I wrote about this, including links to some of the research surfacing at the time. More and more evidence is accumulating showing the effect of fetal hormonal influences.

Elevated Fetal Steroidogenic Activity in Autism. 2014. Popular version:
Children with autism have elevated levels of steroid hormones in the womb From the popular article: “children who later develop autism are exposed to elevated levels of steroid hormones (for example testosterone, progesterone and cortisol) in the womb.” Also, from a BBC article: “Prof Baron-Cohen [one of the study authors] said: “This is one of the earliest non-genetic biomarkers that has been identified in children who go on to develop autism. We previously knew that elevated prenatal testosterone is associated with slower social and language development, better attention to detail, and more autistic traits. Now, for the first time, we have also shown that these steroid hormones are elevated in children clinically diagnosed with autism.”

Remember that there could be any number of sources for unusual hormones. The placenta-uterine interface could be unusually permeable, allowing more of the mother’s hormones through. The fetus could over- or under-produce hormones. Hormones from a non-identical twin can have an influence. Also, this is biology. Everything could work together in varying degrees. As they say, it’s complicated.

Mosaic Epigenetic Dysregulation of Ectodermal Cells in Autism Spectrum Disorder. 2014. Popular article: Study shows environmental influences may cause autism in some cases (“Environmental” in this case refers to the uterine environment of the fetus.) “The researchers detected two groups of genes that were epigenetically distinctive in children with ASD compared with TD [Typical Development] children. Moreover, these genes are known to be expressed in the brain and code for proteins involved in nerve transmission functions previously shown to be impaired in ASD. Interestingly, these two groups of epigenetically distinctive genes weren’t present in all the cells of children with ASD but only in a subset of them—a phenomenon called mosaicism.”

Mustanski et al. 2005. Human Genetics (pdf) This paper discusses the nonrandom inactivation of a given X chromosome. That’s unusual, the mechanism isn’t known, and it would affect males, with their single X, more than females.

Minireview: Hormones and Human Sexual Orientation. J. Balthazart. 2011. (Supposed to be available from NCBI, but link not currently working for me.)

It is not all hormones: Alternative explanations for sexual differentiation of the brain. Davies and Wilkinson. 2006. From the abstract: “[W]hile gonadal hormones undoubtedly play an important role in sexual differentiation of the brain, they are not the only possible mechanism for this phenomenon. In the present review, we discuss the concept that genes residing upon the sex chromosomes (which are asymmetrically inherited between males and females) may influence sexually dimorphic neurobiology directly….”

Molecular studies of dyslexia : regulation and function of DYX1C1. Tammimies. 2011. The gene in question regulates fetal neuronal migration and is influenced by estradiol.

And I could continue on like that through hundreds of references.

One implication, if these traits can have common roots in hormone levels during critical periods of fetal development, is that similar mutations could result in seemingly unrelated traits. A lineage being studied for, say, the heritability of mathematical ability, should also be polled for other brain organization traits. Genetic studies might then more readily pinpoint common mutations which are likelier to underlie the neurological processes.

Switching gears now to talk about social rather than biological implications, fear often seems to surface when there’s any talk of departing from a “genetic” cause of homosexuality to factors that could be manipulated.

I think that fear is misplaced on several counts. One is that purely as a practical matter, genes are not immutable. Their expression, which is what we care about, is hugely influenced by the environment. Furthermore, it’s only a matter of time before all genes can be directly manipulated. Basing acceptance of a trait on its genetics is very shaky ground to stand on.

The bigger problem, though, is what the nothing-but-genetics attitude implies. The idea is that it forces people to accept homosexuality because it’s a not-my-fault-I-found-it-that-way situation.

That’s silly. It accepts the frame that difference from the majority is a “fault” that should be erased if one could. Instead the point is that difference is okay. Whether it’s genetic or congenital or learned or chosen does not matter. We need all the Einsteins and Marie Curies and Oscar Wildes we can get.

Last, and most important, as a matter of principle, rights have nothing to do with genetics. Everybody has the right to make their own choices, so long as they don’t actively harm others. As I said in the earlier post, “the most important point is that genetics says nothing about how people should live their lives. The most important point is that sexuality is nobody’s business but your own. It doesn’t matter whether it’s a choice or not. The whole debate is useless, because the whole debate is nobody’s business.”

Gay gene: it’s not what you think –part 1

This article in the Beeb set me off: The evolutionary puzzle of homosexuality. The idea being that gay people have fewer children which puts them at a selective disadvantage which means the gene ought to die out.

It’s a gender difference. Must be genetic.

This sort of thing drives me nuts. Who said there’s a gene? They’ve never managed to find one yet. Probably for the obvious reason that there have to be hundreds for any complex trait. That’s clear to some people. From the article, “Dr William Byne, editor-in-chief of the journal LGBT Health, believes sexuality may well be inborn, but thinks it could be more complicated than some scientists believe.” (He’s too polite.)

Who said the genetic traits have anything to do with desire? Genes code for biological traits; how those manifest in social interactions is not genetic.

Who said that in humans having flocks of kids is the ticket to success? It reminds me of how people agonized over the many children poor people had. The rich would be swamped! And yet, oddly enough, the rich survived just fine, thank you. The whole approach is so wrong it has no chance of ending up right. Garbage in, garbage out.

And it continues.

“The genes that code for homosexuality do other things too.” If those things confer an advantage on the reproducing members of the species, then the trait should survive. That makes perfect sense. So do they stop there? Nooo.

There are two or more ways this might happen. One possibility is that the allele confers a psychological trait that makes [each sex more attractive to the other.] … “We know that women tend to like more feminine behavioural features and facial features in their men.

Who’s “we,” kemosabe? That’s bullshit, unless you define the non-gorilla look as “feminine.” And if you do, it exposes your assumptions but they have no actual explanatory power regarding mutual attraction between any gays or straights who aren’t you.

Another way a “gay allele” might be able to compensate for a reproductive deficit is by having the converse effect in the opposite sex. For example, an allele which makes the bearer attracted to men has an obvious reproductive advantage to women. If it appears in a man’s genetic code it will code for same-sex attraction, but so long as this happens rarely the allele still has a net evolutionary benefit.

You’d think if that was much of a factor there’d also be a selective advantage for men who wanted to be attractive to women. Instead we have whole societies geared to caging women instead. That, believe me, is the opposite of attractive.

Another one that makes no sense:

Paul Vasey’s research in Samoa has focused on … [t]he idea is that gay people compensate for their lack of children by promoting the reproductive fitness of brothers or sisters…. Sceptics have pointed out that since on average people share just 25% of their genetic code with these relatives, they would need to compensate for every child they don’t have themselves with two nieces or nephews that wouldn’t otherwise have existed.

Two extra surviving children for every gay relative would be quite a remarkable pattern. But nobody’s remarked on it at a population level. The occasional individual might have that effect, but that wouldn’t be enough for a population-level propagation of “gay genes” which is what the kin selection theory postulates.

Gay people do have children.

Finally, something that is indeed a way to pass on gay genes. However, I don’t remember seeing results showing a much higher incidence of homosexuality in the biological children of gay people. That would support the point that “gay genes” probably don’t code for gayness but for something else.

So there’s a whole string of obvious indications that there is no gay gene, singular, and that the primary functions of gay genes, plural, is something other than homosexuality. And yet the take-home message in popular media is “Gee whiz. This is so hard to fit into a story about men chasing after women for sex. How is that possible?”

Next post: some promising ideas that might actually bear some relation to reality.

“Bergdahl could be prosecuted”

The top-ranking US military officer has raised the possibility Sgt Bowe Bergdahl could be prosecuted if he abandoned his post before his capture.

Seriously? I mean, seriously?

If you read this blog, you know I’m not exactly pro-military. But anyone who has spent five years alone among a bunch of irregulars like the Taliban, never knowing which moment might be his last, has suffered quite enough. It no longer matters what he has or hasn’t done.

And the same goes for the people held for years without trial in Guantanamo, even though they’re supposedly the prisoners of an actual government that (used to) follow some kind of rules.

Once upon a time they said the bad reception given to Vietnam vets when they returned was a disgrace. What’s this then?
