Political phrenology

Sigh.....here we go again. The mass public mind seems drawn to the concept of a "gene for" some complex trait like homosexuality, criminality, intelligence, etc. Having read a fair bit of evolutionary biology, I know well how far removed such simplistic thinking is from the way genetics actually works; yet the mainstream media seem all too inclined to cater to it -- perhaps in the same spirit that they often still have a horoscope tucked away somewhere. The current example is a claim that current brain research is finding a genetic basis for people's political views.

A few basic facts to bear in mind: Most genes influence more than one trait. Most traits are influenced by more than one gene. The development of a complex organism like a human, especially brain structure, is massively influenced by the environment, which interacts with the genome in highly complex ways as the organism develops. As a human learns and develops and changes his ways of thinking, the brain physically re-wires itself to reflect those changes (in fact, the brain re-wiring probably is those changes).

The idea that genes could determine political views in any simple or straightforward way (never mind "political views 'hard-wired' into your brain", in the words of the article's amazingly-stupid headline) is immediately belied by the fact that very many people change their political views over time; in fact, some people change their political views drastically and quickly as a result of a single experience or exposure to new ideas. For that matter, the very meaning of political right and left varies over time and from place to place. In the US, the left-vs-right divide is primarily a matter of secular vs intensely-religious world-views, and church attendance correlates with voting patterns better than any other factor does; in Britain, where this story originates, both left and right are mostly secular and the differences lie in other areas.

Looking at the specifics of the story:

It's quite possible that there are genetic propensities to be fearful and irrational, and that some people's genomes contain genes which code more strongly for that trait.

It's quite possible that people born with genes which predispose them to be fearful or irrational are, in fact, somewhat more likely to grow up to actually be more fearful and irrational than average, although I'd expect that any such predisposition would be mostly swamped by the influence of life experiences.

It's quite possible that people who are more fearful or irrational than average (whether the main reasons are environmental or genetic) have brain structure which visibly reflects this.

It's even possible that people who are more fearful or irrational than average (whether the main reasons are environmental or genetic) are somewhat more likely to become more politically conservative, although one could easily think of a dozen other factors which would likely have a larger influence on a person's political views.

So, yes, there could be some correlation between genes and political views, but it would be too fuzzy and indirect to tell us anything of value about actual people.

Look, it's only a few decades since some people were claiming that blacks or women were genetically hard-wired for traits that made them unsuited for full citizenship. Enough is enough.

About the whole idea that something as complex as a person's world-view could be genetically determined in a straightforward way, I liked this item -- but at least it was intended as a joke.

The fall of DADT -- reactions

I have long thought it ironic that if Alexander the Great (one of the greatest military leaders in history) were alive today, he would not be allowed even to enlist in the US Army. After all, he never made any effort to hide his sexual orientation.

Now, however, the twenty-first-century United States is finally about to catch up with fourth-century-BC Macedonia on this point.

The Huffington Post has an early round-up of statements on repeal from prominent figures; Christian Right leaders and politicians beholden to them are predictably hostile, with most others being supportive. Josh Gerstein sees the vote as inevitable bowing to a massive cultural shift. Andrew Sullivan takes a similar view and sees it as vindicating Obama's long-game strategy. PoliticusUSA echoes Rachel Maddow's call for the ideological left to start giving Obama some credit. And PZ Myers reminds us that the crazies never sleep.

From the Left lists who voted how in the Senate; FiveThirtyEight analyzes possible motives of Republicans who voted for repeal. West Virginia DINO Joe Manchin's decision not to vote at all is earning contempt from all sides. Prop 8 Trial Tracker looks at the next steps.

Liberal bloggers celebrate: Progressive Eruptions, Hello Mr. President, Mauigirl, Politics Plus, Oliver Willis, Wonkette, and doubtless many others who will post today.

On the right, Frum Forum seems sympathetic to repeal, but the comments thread here -- and at NRO and American Spectator -- suggest a right wing deeply divided between pro-repeal thinkers and the anti-repeal troglodyte element. Regulars at The Crossed Pond (libertarian) side with the former.

My own view: Once DADT has been gone for a while and everyone has gotten used to the fact of some soldiers being openly gay, and none of the predicted disasters have materialized, it will become difficult to find any politician (outside the hard-core fundie crowd) who wants to advertise the fact that he ever opposed repeal. But that won't stop them from being just as obstructionist, the next time an opportunity arises to block progress.

Update 1: A few more blogger reactions: Rmuse at PoliticusUSA, The Immoral Minority, and (on the right) Bungalow Bill.

Update 2: More from Skepchick, Mario Piperni, and 365gay. Right Wing Watch has a round-up of Christian Right reactions (found via Republic of Gilead, which has more).

Misconceptions about evolution

I recently made the error of getting drawn into a "debate" with an evolution-denialist in the comment thread on another blog. I quit after a couple of exchanges because (a) the argument was as pointless as such arguments usually are, and (b) it was off-topic from the posting on the blog. However, it reminded me of one reason why such arguments are usually pointless: most evolution-denialists have such basic misconceptions of evolution that they don't even understand what they're rejecting.

Here are some of the mistaken ideas about evolution commonly held by denialists:

Evolution is a "random" process. A couple of times the person I was arguing with used the common tactic of pointing to some complex biological system or process and saying it could not have arisen by random chance or "happenstance". Well, of course it didn't. Evolution is not a random process. Mutation and the re-shuffling of genes by sexual reproduction are pretty much random, and those are the main sources of variation within populations. But the driver of evolution is natural selection, which is anything but random. Genetically-inheritable traits which make an organism more likely to survive and reproduce cause the organisms which carry them to survive and reproduce better than their competitors, and their success means that the genes for those traits (and thus the traits themselves) tend to become more widespread. This process preserves and spreads traits which enhance survival and reproduction, while filtering out those which do the opposite. This is not "random chance".

Evolution is an explanation of origins. It's surprising how often evolution-denialists bring up the big bang, seemingly thinking it has something to do with evolution. Evolution is a theory of the development of life. It does not claim to explain how life got started in the first place (natural selection only works when there are already self-replicating structures of some kind -- it does not explain how the first self-replicating molecules arose), much less the origin of the physical universe. As it happens, we now have a pretty good understanding of the origin of the universe, while the origin of life is harder to explain; but neither of these questions has anything to do with evolution.

"Just a theory". In common usage, the word "theory" is often used to mean a mere hypothesis or even just a guess. In science the word has a different meaning: a system of ideas which successfully explains a wide range of observed phenomena and is supported by a great deal of evidence. That's the sense in which scientists call evolution a "theory". They don't mean there is any serious doubt that it is the correct explanation for the development of life.

Evolution disproves religion. This depends on what one means by "religion". Evolution is incompatible with the stories in Genesis and with other specific beliefs of various religions (and claiming that Genesis is some sort of allegory of evolution is nonsense); so, since we know evolution did in fact happen, those specific beliefs have been proven false. However, evolution doesn't disprove the very existence of gods or other supernatural entities -- it says nothing about them at all, except that they are not necessary to explain the development of life. It's possible to imagine a god creating the universe and evolution then happening by itself, once self-replicating molecules had appeared somewhere within that universe. I don't believe there are any such entities, but evolution says nothing about their existence either way. Again, it's two separate questions.

Christmas cheer

Korans roasting on an open fire.....
Jazzed cops nabbing pedo priests.....
You'll find gays being wed as they desire.....
And folks defiling eucharists.....

What a year it's been! But as December begins, one's thoughts turn to Christmas shopping. Some people aren't so easy to buy for, but I've thought of a few appropriate gifts.....

For Rich Iott: a catalog of Halloween costumes, clown suits, and ComicCon outfits, because anything, absolutely anything, would be an improvement.

For Christine O'Donnell: a vibrator with plausible deniability.

For Pastor Terry Jones: a Koran printed on flame-proof paper, in the hope that he'll realize the best way to attack Islam is to make people read the damn thing, not burn it.

For Joe Miller; a heavy-duty electric razor, so he can finally stop looking like he spent last night in a dumpster.

For Sarah Palin: a detailed map of East Korea, so she can work on planning the first war she'll start if she ever becomes President. Also a note-pad, so she doesn't need to go back to the writing-on-the-hand thing.

For Richard Dawkins: another year of his ideal arch-enemy.

For the racists of the world: a lesson from the salamanders.

For the altar boys of the world: spray-on relief.

For Senate Democrats: a spine apiece.

For the Hollywood movie industry: the collected works of Larry Niven, Brian Lumley, William Barton, and Richard Matheson, in the hopes of inspiring some decent science-fiction and fantasy movies (and a round of floggings for what they've already done to I Am Legend).

For the office HOPA: Jenny's chutzpah.

For the Pope: Tim Minchin on an endless loop, so he can finally get it through his skull how he and his look to the rest of the world.

For the Tea Party movement: all the Thunderbird they can drink, in the hopes that they'll adopt it as their new symbol and cease to sully own my favorite beverage by associating themselves with it. (Calling them thunderbirds instead of teabaggers would actually fit well -- it would evoke the marionettes from the old kids' TV show, who acted like mighty warriors but were actually cheap puppets manipulated by barely-hidden string-pullers.)

And finally, for all of those liberals who react to every defeat by proclaiming the end of all hope, the death of democracy, the final triumph of fascism, etc.: this posting.
