Trying to link atheism and Asperger's syndrome

http://www.examiner.com/x-21239-Oakland-Skepticism-Examiner~y2010m6d3-What-atheism-and-Aspergers-syndrome-share-in-common-and-a-look-at-purpose-driven-answers

From Examiner:

"A recent post over at the Scientific American Mind and Brain blog has been getting a lot of attention in the past few days and not without reason. According to the column's author a graduate student from Belfast has found a correlation between those diagnosed with Asperger's syndrome, a high-functioning form of Autism known for poor sociality and narrow interests, and Atheism.

Specifically, this researcher asked participants to given open answers to questions regarding significant events in their lives and both groups - the atheists and those with Asperger's - ranked high in non-teleological answers. What this suggests on the surface is a similarity in thinking, some sort of shared cognitive process. I for one, have my doubts.

First, definitions.

Teleology is the study of purpose, from the Greek telos. If I were to show you long handled object with a blunt head and two rounded hooks protruding from the tip and ask you what it did, you would probably infer that it was meant to hammer nails - this is teleology, deciphering purpose.

When anthropologists attempt to determine whether a stone they found is a Oldowan stone-axe or a irregularly shaped rock, they must engage in teleological reasoning to reach an informed conclusion. At the same time when you ask a child "Why are rocks pointy?" their answer will invariably be along the lines of "so they can cut things."

Where things get interesting in psychology is where the developmental line between "Rocks are pointy so they can cut things" and "Rocks are pointy because, as mineral formations, they fracture along sharp divides, forming narrow ridges and points." Generally speaking, children are more likely to give a teleological answer to a question than an adult.

Where this is not true or at least not as true is areas of personal experience or importance. Ask an adult why they were the sole survivor of that car accident and you will rarely find someone who says it was luck, or gives some other "mundane" answer. More often you'll find them searching for purpose - telos. They were thrown clear of that accident because God has a plan for them, or they were supposed to survive because they had something left to accomplish, etc.

What this means for the study.

First of all, a warning: I write this based off my reading of a blog post which in turn was based off the memory of a talk delivered at a conference. Parity is not going to be high here. Hopefully we get some juicier details from the authors themselves in the near future, but in the meantime...

Finding that Asperger's patients engage in far less teleological reasoning than their "neurotypical" counterparts is very interesting. Drawing the connection from that to Atheism is a stretch. While true that both groups responded to questions in similarly non-purpose driven manners, one detail shears this tenuous connection.

The atheists, as expected, often invoked anti-teleological responses such as “there is no reason why; things just happen.” The people with Asperger’s were significantly less likely to offer such anti-teleological explanations than the atheists, indicating they were not engaged in teleological thinking at all. (The atheists, in contrast, revealed themselves to be reasoning teleologically, but then they rejected those thoughts.) [Emphasis mine]

Those with Asperger's may in some way simply not be conceiving of things teleologically (and a study between adult Asperger's and children Asperger's against neurotypical peers would be great to investigate this further) the Atheists in the study clearly do possess that function. Rather, they have made a conscious choice to disregard it in favor of more mechanical or naturalistic explanations.

To illustrate this with real events, consider two situations. Several months ago I was having a conversation with my sister while walking to the store. Just as we reach the corner of the street we need to cross, the light turned green and the walk sign lit up. Turning to me she said "Don't you just love that? I always feel like the light turns green just for me when that happens."

As a matter of fact I do love that, and I have often felt the same way. Now of course it isn't true, the light simply happened to turn green at that moment. In some deep recess in our minds however, we both saw an action - the light changing color - and derived a purpose - it wanted to, so we wouldn't have to slow our step. Not being idiots and having a basic understanding of how our local traffic lights work, we didn't believe this teleological answer and instead favored the mechanical explanation. We're traffic-light atheists you might say.

Religious people, along with other forms of magical thinking, are more often the ones who really do believe the traffic light changed for them - though not with quite such mundane events. (Which is why, I'm sure, the study this is all about asked people about significant events in their lives.)

Since we covered atheism with a real world example, we have another real world event that demonstrates precisely the opposite. In one of my earliest articles, Imagining Divinity, we looked at two very different cultures worlds apart, where two religious groups came to supernatural conclusions about the purpose of two natural events.

At the time the Evangelical Lutheran Church in America (ELCA) was struggling with whether or not to allow homosexual men to serve as pastors in their churches. During one of the days this debate was being had a tornado swept through the town damaging several buildings - including the conference center hosting the ELCA. One conservative pastor was quoted saying "The tornado in Minneapolis was a gentle but firm warning to the ELCA and all of us: Turn from the approval of sin. Turn from the promotion of behaviors that lead to destruction."

In other words the purpose of the tornado of the tornado was to send a warning. Examples of this can be found everywhere in religion, so it comes as absolutely no surprise that those who consciously reject religion also consciously reject the forms of thinking religion exemplifies - with the vast majority of the worlds population some manner of theist, the average "amount" of teleological thinking is going to be skewed in that direction.

Another way to look at it is, perhaps I'm putting the cart before the horse. Perhaps I should be saying the "amount" of teleological thinking is responsible for the high percentage of religious persons.

Either way, atheism and Asperger's may share an affinity for the mechanical and naturalistic, but an affinity is all it probably is."

Why Do Atheists Exist?

http://www.truthout.org/why-did-god-create-atheists60189

Greta Christina asks, "Why Did God Create Atheist"?

Why did God create atheists?

This is a question I always want to ask religious believers. (One of many questions, actually. "What evidence do you have that God is real?" and "Why are religious beliefs so different and so contradictory?" are also high on the list.)

If God is real, and religious believers are perceiving a real entity... why is anyone an atheist? Why don't we all perceive him? If God is powerful enough to reach out to believers just by sending out his thoughts or love or whatever... why isn't he powerful enough to reach all of us? Why is there anyone who doesn't believe in him?

It seems to be a question that troubles many believers as well. At least, it troubles them enough that they feel compelled to respond. And as atheism becomes more common and more vocal, this compulsion to respond seems to be getting more common and more vocal as well.

I've seen a couple of religious responses to this question. Neither of which is very satisfactory. But they keep coming up... so today, I want to take them on.

Open Your Heart To Me, Baby

For more traditional believers, the answer to why atheists exist is simple: Atheists have closed our hearts to God. God has reached out to atheists -- but we don't want to believe. We want to pursue a selfish and sybaritic life, and don't want to obey God's laws (so say the real hard-liners)... or we've been hurt by life or by religion, and we're rejecting God out of anger (so say the marginally more compassionate believers). But it's important that we have free will -- so we have to be free to reject God as well as to accept him. God can't force us to believe. That would be cheating.

Uh huh.

See, here's the problem with that.

Or rather, here's a whole set of problems.

For starters: This idea is totally unfalsifiable. There's no way to prove that you honestly gave religion a chance. Until we develop the technology to accurately record the inside of somebody's head and play it back in somebody else's, there's no way to prove that atheists are sincerely open-minded and willing to consider religion.

Atheists can say a hundred times, "Really, I'm telling you, I've looked at this carefully, I've meditated on it, I've examined the evidence, I've studied lots of different religions... and I just don't find any of it convincing." We can ask believers to give us good evidence or arguments for God. We can point out the pain and distress many of us went through when we let go of our beliefs -- pain and distress that this "You've just closed your heart to God" trope seriously trivializes. We can even go out on a limb and point to the kinds of evidence that would convince us we were mistaken (something just about no religious believers are willing to do). But since we can't demonstrate the state of our minds and hearts, believers can always say, "You aren't sincere. Your mind and heart are closed."

There's no way to prove that they're wrong. It's an unfalsifiable hypothesis.

Which makes it an entirely useless one. If there's no possible way to show that your hypothesis is false, there's no way to know whether it's true.

What's more, the "You've hardened your heart against God" trope is a perfect example of moving the goalposts. No matter how many times we gave God the old college try... we clearly haven't tried hard enough. I mean -- we don't believe! If we'd tried hard enough, then obviously we'd believe! The fact that we don't believe is proof that we haven't tried hard enough. Q.E.D. (It's a fairly entertaining logical fallacy, actually: a unique blend of moving goalposts and circular reasoning. I'm kind of impressed.)

And then, of course, we have the niggling little problem of self-deception and rationalization.

The human mind is very prone to believing what it already believes. It's very prone to believing what it's been prompted to believe. And it's very prone to believing what it wants to believe. Rationalization is a deeply hard-wired part of how the human mind works, and while it's a surprisingly important part -- among other things, it enables us to get on with our lives without being totally paralyzed -- it's something we always need to keep in mind when we're deciding if the things we believe are really true.

So if the only way to believe something is to try really, really hard? If what it takes to believe something is to "open your heart" -- i.e., to put yourself in a state of suggestibility and wishful thinking?

That's not a very good sign that this something is true.

Quite the contrary.

If we care about whether the things we believe are true -- if we want to be sure that we're not just fooling ourselves into believing what we already believe or what we want to believe -- then the times we're trying really hard to convince ourselves of something? Those are exactly the times we should be most skeptical. That's not when we should be opening our hearts. That's when we should be on our guard.

The reality for me, and the reality for a whole lot of atheists? I am open to my mind being changed. Heck, I used to be a believer. I used to be more than just open to the idea of God -- I used to believe in God. (Or something that I was willing to call God.) In fact, it was my willingness to change my mind, my openness to reconsidering new possibilities, that led me to let go of my religious beliefs in the first place. And if someone can give me some really good reasons to change my mind back again, I will.

But "You just have to open your heart" is not a good reason. It's an unfalsifiable argument -- nothing I do can prove that I'm sincerely open to the God hypothesis. Its goalposts can be moved forever -- no matter how carefully I've considered religion, people can argue that I need to consider it just a little more. And it's basically a defense of wishful thinking as some sort of positive virtue. (Besides, nobody's ever given me a good reason why I should open my heart to their particular god: why I should open my heart to Jesus instead of to Allah, or Ganesh, or the Goddess, or that blue peacock god some people worship in northern Iraq.)

"You just haven't opened your heart" is clearly a terrible explanation for why God would allow atheists to exist.

Are there any better ones?

I Love You Just The Way You Are

There is another religious response to the puzzling question of why there are atheists. And unlike the unfalsifiable, goalpost-moving, "let's treat people like pariahs for wanting to be careful that the things they believe are true" hostility of "You haven't opened your hearts," it's a response that typically comes from more progressive, tolerant, pluralistic believers.

It's this: "God doesn't care if you're an atheist."

"As long as you're a good person," this idea goes, "as long as you love other people and try to do right by them, God's fine with you. God doesn't need your worship or your praise, or even your faith. God loves atheists, too. He doesn't care whether you believe in him."

Yeah. See, here's the problem with that.

God may not care whether I believe in him.

But I do.

I want to understand the world. I care about reality, more than I care about just about anything. If there really is a God who created everything, who guided the universe and the process of evolution so conscious life could come into being, who animates all life with his spirit -- I bloody well want to know about it. I don't want to be flatly wrong about one of the hugest questions humanity is faced with. In my years as an atheist writer, I keep asking believers again and again, "Do you have some evidence for your belief? If you do, please tell me about it. I want to see it." And I'm not being snarky, or baiting them into a debate I know they can't win. (Well... not mostly.) If I'm wrong about this, I sincerely want to know.

Why does God deny me that knowledge? Why does he give it to some people, and not others?

And maybe more to the point:

If there really were a loving creator of the universe who animates all life including my own, and from whom all that is good and valuable about the world emanates, I wouldn't want to be alienated from him. I'd want to be connected with him. (Her. It. Them. Whatever.) Especially the touchy-feely God that the progressive, tolerant, pluralistic believers believe in. There are certainly plenty of gods I wouldn't worship even if I thought they were real -- the God of fundamentalist Christianity is a sadistic nutjob, and even if he existed I wouldn't give him the time of day. But the warm, gentle, "source of all life/ force of goodness and love in the universe" God that progressive believers believe in? Sure, I'd want to know him. I'd have some serious questions for him -- why is there suffering, why is there evil, why can't the Cubs win a goddamn pennant to save their lives -- but I'd happily have a beer with the guy. We could be friends. I mean, he's the source of all life, the force of goodness and love in the universe. Of course I'd want that in my life. Why on earth wouldn't I?

If God exists... then why isn't he reaching out to me? Isn't it cruel of him to reach out to some people but not to others? (Not to mention the manipulative game-playing he seems to be doing, where he reveals himself in wildly different and even contradictory ways to different people, and then sits back while they duke it out over which one is right.) Why does he manifest in some people's hearts, but not in others? Why is he being such a passive-aggressive jerk?

Let me be very clear about this: I am entirely happy to be an atheist. I'm not one of these whiny, moody, "I wish I could believe" atheists that so many believers think is the only valid kind of atheism. I am tickled pink to be an atheist. I won't pretend that I didn't lose a form of comfort when I left my beliefs -- but I gained so much in return that the loss is a clear bargain. And the comforts I have now are far more comforting... since they're built on a foundation of reality. I don't have the constant nagging feeling in the back of my head that my beliefs are just wishful thinking, and that I've built my philosophy on a foundation of sand. I'm persuaded that God does not exist, and that's just ducky with me.

But I'm happy with my atheism because I'm persuaded that it's correct. I'm happy not feeling God in my life because I'm persuaded that God doesn't exist.

If God really existed, I sure as heck would want to know about it.

So why don't I?

If God really exists -- why don't I know about it?

As an atheist, I have some really good answers for why people believe in God even though he doesn't exist. The human mind is prone to numerous cognitive errors -- and many of those cognitive errors make people susceptible to religion. We tend to see intention, even where no intention exists. We tend to see patterns, even where no pattern exists. We give excessive weight to personal emotional experience, and aren't good at applying critical thought to those experiences. We don't have a good intuitive understanding of probability, and tend to think events are more improbable than they really are. We tend to believe what authority figures tell us. We tend to believe what we're taught as children. We tend to believe what people we know and trust tell us. We're reluctant to question the things that everyone else in our social group believes. Etc., etc., etc. People believe all sort of things that aren't true... and from an atheist/ materialist viewpoint, that makes perfect sense. Atheism is not even a little inconsistent with the belief in gods who don't exist.

But the belief in God is very much inconsistent with the existence of atheists. I have yet to see a religious believer give a good answer for why God exists -- but not everyone experiences him or believes in him. I have yet to see a good answer for why God bestows the experience of his existence (however inconsistently and contradictorily) onto some people -- but not onto others. I have yet to see a good answer for why God is all-powerful and all-knowing and all-good -- or even anything close to all-powerful and all-knowing and all-good -- and still isn't perceived by everybody.

Material for Evolution

http://news.oneindia.in/2010/06/02/jumpinggenes-provide-extensive-raw-material-forevolution.html


Jumping genes provide extensive 'raw material' for evolution, an American study has shown.

Researchers at the University of Pennsylvania School of Medicine found that any two peoples' genomes differ at roughly 285 sites out of the 1139 sites studied.


These results were found by scanning the genomes of 25 individuals, 15 of which were unrelated.

Jumping genes - also called transposons - are sequences of DNA that move to different areas of the genome within the same cell.

Study co-author Haig Kazazian, Seymour Gray Professor of Molecular Medicine, in the Penn Department of Genetics, said:

"The significance of this work is that there is much more diversity in our genome due to insertions by this family of transposons than previously thought.

"This movement of genetic material provides the raw material of genetic evolution, and it doesn't take into account the insertions that we believe occur outside of the sperm and egg cells studied in this project."

Transposons are a source of diversity within a species' gene pool, with implications on many levels.

For example, slight changes in genes help organisms adapt and survive in new environments, and populations with genetic diversity are less vulnerable to disease and problems with reproduction.

Insertions into certain spots in the genome can also cause cell function to go awry, so understanding their placement and variation in the human genome is important for a fundamental understanding of disease.

Insertions can cause many genetic diseases, such as hemophilia and Duchenne muscular dystrophy, and may play a role in the development of cancer.

Retrotransposons are the major class of jumping genes, with the L1 family the most abundant type of retrotransposon in the human genome.

L1s comprise about 17 percent of the human genome.

Eventually, continuous jumping by retrotransposons expands the size of the human genome and may cause shuffling of genetic content.

For example, when retrotransposons jump, they may take portions of nearby gene sequences with them, inserting these where they land, and thereby allowing for the creation of new genes.

Even otherwise unremarkable insertions of L1s may cause significant effects on nearby genes, such as lowering their expression.

Retrotransposons move by having their DNA sequence transcribed or copied to RNA, and then instead of the genetic code being translated directly into a protein sequence, the RNA is copied back to DNA by the retrotransposon's own enzyme called reverse transcriptase.

This new DNA is then inserted back into the genome.

The process of copying is similar to that of retroviruses, such as HIV, leading scientists to speculate that retroviruses were derived from retrotransposons.

The team also found that on average 1 in 140 individuals have obtained a new L1 insertion from their parents.

When all retrotransposon insertions, including L1 and others, are considered about 1 in 40 individuals have received a new insertion from their parents.

The current study counted insertions in the heritable germ cell line, that is in egg and sperm cells.

Kazazian said: "The real elephant in the room is the question of the incidence of somatic insertions, insertions in cells that aren't eggs or sperm.

"We don't yet know the incidence of those somatic insertions."

The findings of the study appear online in Genome Research. (ANI)

Bad News from Queensland

http://www.heraldsun.com.au/news/national/creationism-to-be-taught-in-queensland-classrooms/story-e6frf7l6-1225873019548

I feel bad for the children. They are going to be taught that the crackpot idea of creationism as a "controversy". Right, that controversy that doesn't exist in the scientific world. To be fair this isn't being taught in science class but framing it is a controversy is the wrong way to go.

Creationism Where it Doesn't Belong

http://www.guardian.co.uk/uk/2010/may/26/northern-ireland-ulster-museum-creationism

"Northern Ireland's born-again Christian culture minister has called on the Ulster Museum to put on exhibits reflecting the view that the world was made by God only several thousand years ago.

Nelson McCausland, who believes that Ulster Protestants are one of the lost tribes of Israel, has written to the museum's board of trustees urging them to reflect creationist and intelligent design theories of the universe's origins.

The Democratic Unionist minister said the inclusion of anti-Darwinian theories in the museum was "a human rights issue".

McCausland defended a letter he wrote to the trustees calling for anti-evolution exhibitions at the museum. He claimed that around one third of Northern Ireland's population believed either in intelligent design or the creationist view that the universe was created about 6,000 years ago."


"Anti-Evolution" he sure doesn't mince with words. How about, anti-intellectual, irrational, dead-brain, idiotic?

""I have had more letters from the public on this issue than any other issue," he said.

The minister said he wrote a "very balanced letter" to the museum because he wanted to "reflect the views of all the people in Northern Ireland in all its richness and diversity".

Earlier in his letter to the museum's trustees McCausland said he had "a common desire to ensure that museums are reflective of the views, beliefs and cultural traditions that make up society in Northern Ireland".

His call was condemned by the evolutionary biologist Professor Richard Dawkins, who said: "If the museum was to go down that road then perhaps they should bring in the stork theory of where babies come from. Or perhaps the museum should introduce the flat earth theory."

Dawkins said it was irrelevant if a large number of people in Northern Ireland refused to believe in evolution. "Scientific evidence can't be democratically decided," Dawkins said.

McCausland's party colleague and North Antrim assembly member Mervyn Storey has been at the forefront of a campaign to force museums in Northern Ireland to promote anti-Darwinian theories.

Storey, who has chaired the Northern Ireland assembly's education committee, has denied that man descended from apes. He believes in the theory that the world was created several thousand years ago, even though the most famous tourist attraction in his own constituency – the Giant's Causeway on the North Antrim coast – is according to all the geological evidence millions of years old."


Faith: causing humans to deny the obvious.

"Last year Storey raised objections to notices at the Giant's Causeway informing the public that the unique rock formation was about 550m years old. Storey believes in the literal truth of the Bible and that the earth was created only several thousand years before Christ's birth.

This latest row over Darwin versus creationism in Northern Ireland comes at a delicate time for the Ulster Museum. Earlier this month it was shortlisted for the UK's largest single arts prize. The Art Fund Prize annually awards £100,000 to a museum or gallery for a project completed in the last year.

The belief that the Earth was divinely created in 4004 BC originates with the writings of another Ulster-based Protestant, Archbishop of Armagh James Ussher, in 1654. Ussher calculated the date based on textual clues in the Old Testament, even settling on a date and time for the moment of creation: in the early hours of 23 October."

The Vatican Is Taking All Challengers (See Below for Exceptions)

http://www.examiner.com/x-2044-Atheism-Examiner~y2010m5d31-Vatican-excludes-Richard-Dawkins-and-Christopher-Hitchens-from-atheist-debate-guest-list

The Vatican is ready to have people challenge its' ideas. Or is it?

"In an effort to improve relations between non-believers and the Catholic Church, the Vatican has decided to host a series of debates in Paris. The pope ordered that a foundation be established to facilitate open dialogue between atheists and agnostics and top Catholic theologians.

The foundation, Courtyard of Gentiles, which was set up by the Pontifical Council for Culture, hopes to host the debates next year. Even though the church is opening its doors to atheists, they are being selective about which atheists will be allowed to participate. According to a report on The Independent Web site, "militant" atheists, especially those who have "high public profiles such as Richard Dawkins and Christopher Hitchens will not be invited."

The president of the Pontifical Council for Culture, Archbishop Gianfranco Ravasi, told the National Catholic Register earlier this month that they were prepared to host non-believers who were of the "noble atheism or agnosticism" persuasion. He said that "polemic" non-believers like Piergiorgio Odifreddi, Michel Onfray, Richard Dawkins, and Christopher Hitchens would not be invited. He added that those kind of atheists meet the truth with "irony and sarcasm."


I know plenty of atheists who dismiss "the truth" with "irony and sarcasm". I wouldn't call them high profile either. The Vatican is really limiting its' choices here. Perhaps they are afraid of being owned by the atheists?

Dan's the Man

http://www.usatoday.com/news/opinion/letters/2010-06-01-letters01_ST2_N.htm

Daniel Dennet responding to criticism of the New Atheists:

"Commentary writer Karl Giberson apparently is so rattled by the New Atheism that he cannot quote accurately ("Atheists, play well with others," On Religion, May 24).
In the Forum piece, he says of me: "Tufts University philosopher and leading atheist Daniel Dennett no doubt finds all this mystifying, since he thinks seminary education should ultimately terminate one's faith: 'Anybody who goes through seminary and comes out believing in God hasn't been paying attention,' he told The Boston Globe." As the Globe article made clear, I was quoting a joke made by a pastor. If this were an isolated incident, I wouldn't bother responding, but faith fibbers like Giberson are polluting the media with their misrepresentations of the New Atheism.

We New Atheists don't need to tell lies to get our points across; the truth is damning enough. Our critics seem to have decided that telling the truth is just not a strong enough weapon to ward off the threat they see us posing. They should reflect that their willful misrepresentations dishonor the faiths they are defending.

Daniel Dennett; North Andover, Mass."
