Tortured logic, tortured justice

Sometimes, I cannot comprehend how the United States of America has come to occupy the landscape that it has in the year 2009. Growing up, I learned in school about all of the wonderful things that the United States had done for the world. Out of the tyranny that the British Empire had become, our forefathers had the temerity and the moral fortitude to announce to the world that we would be building a new kind of nation-- one in which the rights of the individual would trump government power. People were inherently vested with natural rights, inalienable rights. Our First Amendment- the right to speak freely, to worship (or not) as one pleases, free press, who could ask for a better check on governmental power? Can the government force the citizenry to quarter soldiers? Not here, we've got the Constitution! Governments stopping people for no reason, or on trumped-up charges? No way, we've got the 4th Amendment! To be sure, there were some stark contradictions, but I didn't realize those until I was a little older. I mean, it's a little hard to take seriously those that would lecture on the topic of liberty while being slave-owners, but the overall idea was pretty great. We were the force for truth and justice and all that is right. We proved it, too. We fought tyranny in World War II, the most recent (winning) war. We saw the evil that was done in the name of National Socialism, Fascism, or whatever label you want to use. We saw the evil in those Nazi bastards and we would have none of it-- and rightly so. The indescribable acts of torture and dehumanization were enough to turn anyone's stomach. I read Night, as well as some other works by holocaust survivor Elie Wiesel, and was moved to tears. I looked at the photographs of the concentration camps and saw the shivering, starving groups of people blankly staring at the camera lens. I saw the piles of bodies- massive piles of them! What kind of people could order (or commit?) these horrible, despicable acts? What kind of person could so callously cause the suffering of their fellow human beings? The Nazi experiment was a singular example of the brutality that one group could inflict on another. There is no crime so heinous that it could compare to the atrocities committed by the Nazis. The scale of the suffering defies understanding-- we named it The Holocaust. [More . . . ]

Missouri’s Turn for Anti-Science Ridicule

A minor brouhaha erupted over a t-shirt in Sedalia Missouri. But this isn't about an uppity student. The band director designed an official band t-shirt to illustrate the evolution of brass music. What image did he choose to evoke the idea? Yep, a common ascent-of-man icon from the early 20th century. After some parents saw the shirt proudly worn at the Missouri State Fiar parade, they complained. From the Saint Louis Post-Dispatch:

"I was disappointed with the image on the shirt," said Sherry Melby, a band parent who teaches in the district. "I don't think evolution should be associated with our school."

What sort of science program do you think she had? What sort do you think she would vote for? The school quickly recalled the t-shirts, eating the cost of their production, and will be designing new shirts that don't offend by presenting an image that obliquely refers to actual science. Naturally, Pharyngula jumped on it. And in the Sedalia Democrat, they quote the assistant band director about pulling the shirts,

"If the shirts had said ‘Brass Resurrections' and had a picture of Jesus on the cross, we would have done the same thing," he said.

Apparently there is a strong belief that science is a religion that should not even be tangentially promoted over any other belief. And people wonder why I sometimes write that I live in the state of Misery.

Depression as an adaptation

According to the latest edition of Scientific American Mind, new research suggests that depression is not necessarily a a disease or aberration. In many cases, having a depression might increase your chances of survival.

[D]epression should not be thought of as a disorder at all. In an article recently published in Psychological Review, we argue that depression is in fact an adaptation, a state of mind which brings real costs, but also brings real benefits.
The researchers go out of their way to acknowledge that depression is a terrible problem for many people who should seek out help. Nonetheless, they also suggest that the mode of thinking characteristic of many bouts of depression is focused, highly analytical and systematic:

Analysis requires a lot of uninterrupted thought, and depression coordinates many changes in the body to help people analyze their problems without getting distracted . . . [D]epression is nature’s way of telling you that you’ve got complex social problems that the mind is intent on solving. Therapies should try to encourage depressive rumination rather than try to stop it, and they should focus on trying to help people solve the problems that trigger their bouts of depression . . . [D]epression . . . seems . . . like the vertebrate eye—an intricate, highly organized piece of machinery that performs a specific function.

For further reference: I first rand in to this idea that many bouts of depression might be useful in a book called Why We Get Sick, by Randolf Nesse.

Bugs and their bites

I cleaned out lots of weeds growing in a corner of the yard five days ago, but now I'm paying the price. I've got lots of chigger bites on one of my arms, and do the EVER itch! While looking up recommended treatments--there's not much you can do other than wait and use hydrocortisone cream--I decided to find a photo of a chigger. I found a terrific photo, and much more. If you want to see some excellent photos showing what the most common and most dangerous bugs look like, along with photos of what their bites look like, visit this slideshow by WebMD. You'll see chiggers, mosquitos, brown recluse spiders, black widows, scabies, red ants and much more. It's called the "Bad Bugs Slideshow," which stirs in an unnecessary moral dimension to the topic! But, again, the photos are really well done. You might be interested even if you aren't currently covered with bug bites.

Creative denial of mortality as an evolutionary adaptation?

The August 6, 2009 edition of Nature (available online only to subscribers) includes a fascinating letter by Ajit Varki, a Professor of Medicine and Cellular & Molecular Medicine at the University of California San Diego, La Jolla. Varki begins his letter by recognizing some of the unique features of human animals, such as theory of mind, "which enables inter-subjectivity." These impressive human cognitive abilities might have been positively selected by evolution "because of their benefits to interpersonal communication, cooperative reading, language and other critical human activities." Varki then describes his conversations with a geneticist named Danny Brower (now deceased), who was fascinated with the question of why theory of mind emerged only recently, despite millions of years of apparent opportunity. Brower offered Varki a tantalizing explanation for this delay:

[Brower] explained that with the full self-awareness and inter-subjectivity would also come awareness of death and mortality. Thus, far from being useful, the resulting overwhelming fear would be a dead end evolutionary barrier, curbing activities and cognitive functions necessary for survival and reproductive fitness. . . . in his view, the only way these properties could become positively selected was if they emerged simultaneously with neural mechanisms for denying mortality.
In other words, self-awareness is a double-edged sword that tends to kill off (through terror-induced paralysis) those who become too readily self-aware. Therefore, self-awareness evolved together with denial of death--Brower was suggesting that those who became too clearly self-aware would become incapacitated by something of which chimpanzees, dolphins and elephants remain blissfully ignorant: the fact that they will inevitably die. Image by Puroticorico at Flickr Varki suggests that Brower's idea would not only add to ongoing discussions of the origins of human uniqueness, but it could shed light on many puzzling aspects of human psychology and culture:
[I]t could also steer discussions of other uniquely human "universals," such as the ability to hold false beliefs, existential context, theories of afterlife, religiosity, severity of grieving, importance of death rituals, risk-taking behavior, panic attacks, suicide and martyrdom.
Perhaps we are simply incapable of viewing life "objectively," in that evolution has rigged us up with equipment that protects us by deluding us. It seems, then, that the co-evolution of delusion and awareness (if this is the case) dovetails quite well with Terror Management Theory (TMT), which I summarized in a post entitled "We are gods with anuses: another look at “terror management theory”:

The problem is that the evolution of our powerful ability to be conscious made us aware that we are mortal beings and that all of us are heading toward inevitable death. The “solution” is also offered by our highly developed cognitive abilities: we have developed the ability to wall off our cognitively toxic fear of death by “objectifying” our existences and living idealized lives free from fear of death.

Brower and Varki thus suggest that the ability of humans to be extraordinarily aware and curious is too dangerous to be dispensed by evolution in its pure form. Too much knowledge can might be too dangerous. To safely allow the continuation of the species, human awareness might need to be deluded and distorted in ways that account for some of the most baffling "cultural" aspects of what it means to be human. Image by Latvian at Flickr (creative commons) This approach sounds promising to me, though it also raises many other questions, such as this one: Why are some of us apparently immune from these delusions? Why are some of us much more able to disbelieve claims of gods and afterlives?
