I know not all of you like to listen to podcasts. So I went through it and transcribed a good chunk of what Luke said in his lecture, the parts that I thought were most important. I have a few thoughts afterward. By the way, I missed the beginning for reasons I can’t remember (this took me a couple of days to make it all make sense) but this is a lecture about Dr. Ernest Becker and Terror Management Theory.

Partial transcript:

…This is where we get neurotic about death. It’s the ultimate inferiority complex. Our lifespan is limited. We realize we must die but in striving to overcome that, it creates more problems. We put a lot of energy into denying death.

One way to summarize Becker’s theory: It’s good to have a brain that can plan for the future and be self-aware, but the problem is that when we become scared of our own mortality it sets up a defense against that. Part of the defense involves symbols. We think symbolically and so our symbols set up a barrier. These symbols can be religious, political, symbols of our mastery over the world, symbols of making money, etc.

What Becker thought was that culture itself is a buffer against these threats to our self esteem. We set up our belief in culture and human culture really is an attempt to deal with threats to our own mortality and our self esteem. So first, what is self esteem?

Self esteem is not just a product of you, individually. What Becker thought was that self esteem was something you get a sense of only through other people. So you think of yourself as a valued person who has powers, who can act upon the world, but that is socially validated by parents, siblings, peers, a gradually expanding group of people. This gets more abstract and symbolic as the child grows up. So as a young adult you might latch onto ideologies. For many people this is religion. You join a church and get a sense of what you need to do to be good or bad from those groups too. The good thing is that these groups give you clear guidelines to derive your self esteem.

This can be positive or negative. So if you don’t get positive reinforcement, you’ll look for self esteem and validation in other ways. So this is why people join cults and gangs, etc.

Hero Striving System: whatever you use to seek pride and superiority. Everyone does this in different ways. The system is different for different people but it all boils down to wanting to feel worthwhile.

So cultural symbols can provide a buffer against our mortality fear. How can I transcend death? This is Immortality Striving. It all boils down to “the end is not the end.” This could also be more abstract. Your cultural striving could be symbolic striving against death. You believe your genes and your legacy will pass down even after you die through your children. You create something that will last after your death, like a pyramid, or a lot of money, etc. You’re saying, “I was here, I mattered.” This maintains your self esteem.

Here’s where the problem comes in. If you are so invested in these strivings, in these worldviews to drive your self esteem, that means any threat to those worldviews, to that symbolic system, if they are poked at, is not trivial. This will poke at your self esteem. This person is challenging my worldview. And someone doesn’t even have to be mean to threaten you, because there are different worldviews. Every time you encounter a different person, a different culture, you see the standards of normal differ.

What Becker thought was that being presented with a different worldview is inherently threatening. Because if that guy’s right, he has a different worldview, he seems perfectly happy with his system, and it’s contradictory to my system, there’s a problem for my system.

So a lot of war, strife and prejudice was really about more than just “you’re different, I don’t like you, you have funny gods”, but it’s a threat to our self esteem. So if he’s right, I’m not going to heaven, or there isn’t a heaven.

So an atheist’s world view is very different and therefore very threatening.

People, when confronted with different worldviews have to find a way to deal with it. You can denigrate people (call them stupid); try to convert them to your worldview (proselytize or missionary work) – which validates your worldview and your self esteem; assimilate people – neutralizes the threat by getting them to give up part of it (Native Americans, etc);  accommodation – declaw the other worldview by incorporating some of their elements into ours (like blue jeans, hippy symbols, etc) in a very sterilized sort of way; or annihilate the other worldview – genocide, stamping out everything about the American Indians, even their buffalo, don’t let them speak their own language, etc.

Here’s where Terror Management Theory comes in, with empirical testing. There are 2 main predictions to test:

1. If we threaten someone with mortality thoughts, if we remind them of death, that should result in compensatory response to bolster their worldview.

Mortality Salience Hypothesis (around the 30 minute mark)

2. If we poke at someone’s worldview and suggest that they may not be correct, we should see an increase in their death anxiety. They might become more fearful of their own mortality if their worldviews are challenged in some way.

From the clip of the video, Life and Death: Flight From Death: The Quest for Immortality (video on demand), Flight From Death – The Quest for Immortality (dvd)

The first component of TMT states that individuals need to sustain faith in a meaningful worldview.  The second component states that individuals need to feel as though they are value protected members, objects of significance within this worldview. This is self esteem.

Talk of politics and what kinds of leaders people will choose when their mortality feels threatened: (39 minute mark). (there is a polarizing effect)

There is a reciprocal relationship between threats and my own mortality and worldview.

49:00 – more religious studies: Here’s an interesting one. A group of high fundamentalists (believing in biblical literalism) were confronted with contradictions in the bible, they unconsciously thought about their own mortality more.

What does that mean? What’s at stake? It goes a bit deeper than they just want the bible to be perfect and literal, or that they want to preserve a belief in doctrine. When people are defending religious concepts, their worldview is at stake. When someone pokes at their belief and says your belief isn’t true, or here is evidence against your views, it’s more than just a contradiction of these facts, it’s an emotional reaction the person is going to have because that is their ticket to immortality. It raises fears of their own death when those are challenged.

52:30 – creation and evolution worldview studied with similar results. Creationists who had their worldview threatened had higher unconscious death fears.

Implications: why won’t people accept data on evolution? This study would imply that it’s not simple bullheadedness or dogmatism, it cuts deeper than that. From a TMT perspective, these people are defending their worldview. This is what keeps mortality fears in check. If someone comes along and pokes at that worldview it’s not just a matter of intellectual debate anymore, this is an actual threat to their sense of symbolic immortality.

55:00 Dual nature to mortality salience. Studies show that if you show the positive aspects of a religion, for example, then expose them to mortality salience, the people end up defending a worldview that is more accepting. So religion and politics might contain mixed positive and negative messages. If the positive ones are primed and made more active, the person when under threat defends those more too.

So mortality salience isn’t all about doom and gloom and threats. What this would imply is that, it depends on what message is accentuated.

57:20 What about atheists, who don’t have a worldview of literal immortality? Does that mean that we’re immune from the effects of death threats because we’re not expecting to live for the resurrection, or be reincarnated? That is, we are probably not using that as a security blanket. Essentially Becker says it  doesn’t matter – “It doesn’t matter whether their cultural hero system is frankly magical, religious and primitive, or secular, scientific and civilized. It’s still a mythical hero system in which people serve in order to earn a feeling of primary value, of unshakable meaning. Civilized society is a hopeful belief and a protest that science, money and goods make man count for more than any other animal. In this sense, everything that man does is religious.” So there are just as many non-theistic, nonreligious worldviews that can be defended as religious worldviews. For example, the cult of Stalinism and Mao. Or other things people value like human rights, humanism, science: these things are also worldviews that are defended because they give our life meaning.

Somebody might not say, “I’m going to go to heaven, that’s the only thing that would matter to me”, but they might say that they support these values. That’s their ticket to immortality. So this has the same effect. If anyone pokes at the Bill of Rights, messes with Jefferson, or says that science doesn’t matter, to many people who have a naturalistic worldview that would be just as threatening as people who have religious worldviews. So these theories don’t just apply to people who have supernatural or religious worldviews.

1:00:00 What should people do with this information? The denial of death in our culture is particularly strong. So one way to deal with that is to learn to have a worldview that acknowledges mortality on a regular basis. Live more consciously with those reminders everyday, not in a negative or morbid sense, but in a sense that this is part of life. “This is going to happen to me, and I’m going to make life count now, instead of saying I can transcend and cheat death.”

Also, choose ideologies that don’t rely upon the strident defense of “that guy is threatening my worldview, I’m going to wipe him out”. Ideologies don’t have to be threatening to other people. Make the unconscious conscious. Recognize that this is a bulwark to my worldviews, to recognize when you see a commercial, a political package, or a doctrine that this is really more than what it says. It’s actually a worldview defense. If we make that conscious, we can recognize what it is that we’re doing when we do it. So then we can take a step back and say, “I’m going too far. I’m defending myself against my own sense of insignificance by doing this action.”

1:02:13 There are ways you can strive for immortality in a nondestructive way. It doesn’t necessarily mean you have to strive against other peoples’ worldviews. Find positive ways to find meaning for your lives through positive ways to defend your worldview; charity, supporting other people, etc.

~

If you’ve made it through the transcript and are still with me, congratulations. This isn’t the most fun topic, and this post is really long. But it does have huge implications and can really help us in understanding our own motivations as well as how other people are dealing with their own fears and thoughts.

I have a followup, also by Dr. Luke Galen and the rest of the Reasonable Doubts crew, that will give us some very practical advice in dealing with people and their dogmatic beliefs. But this post was plenty long enough, so I thought I’d save it for later.

I welcome your thoughts.

Update! Boobquake results are in: Our immodest hair and cleavage did not cause any earthquakes. In fact, the mean magnitude of quakes actually went down during the experiment. Read the full results over at Blag Hag.

~

Jennifer over at Blag Hag decided to start something by asking women to dress immodestly to show that it doesn’t cause earthquakes. It was spurred on by some little Iranian man who said:

“Many women who do not dress modestly … lead young men astray, corrupt their chastity and spread adultery in society, which (consequently) increases earthquakes,” Hojatoleslam Kazem Sedighi was quoted as saying by Iranian media. Sedighi is Tehran’s acting Friday prayer leader.

Women in the Islamic Republic are required by law to cover from head to toe, but many, especially the young, ignore some of the more strict codes and wear tight coats and scarves pulled back that show much of the hair.

“What can we do to avoid being buried under the rubble?” Sedighi asked during a prayer sermon Friday. “There is no other solution but to take refuge in religion and to adapt our lives to Islam’s moral codes.”

“A divine authority told me to tell the people to make a general repentance. Why? Because calamities threaten us,” Sedighi said.

Minister of Welfare and Social Security Sadeq Mahsooli said prayers and pleas for forgiveness were the best “formulas to repel earthquakes.”

“We cannot invent a system that prevents earthquakes, but God has created this system and that is to avoid sins, to pray, to seek forgiveness, pay alms and self-sacrifice,” Mahsooli said.

So on April 26, I will show my cleavage for science. I dress for comfort, not looks, so I’m a perfect person to “tip the scales” towards total devastating earthquake on Monday April 26. This is a scientific experiment.

You can read the whole thing over at Blag Hag. She also clarifies that she’s not trying to offend anyone in a follow up.

There is a Facebook Event and you can twitter about it: #boobquake.

Here is what Jennifer says:

Sedighi claims that not dressing modestly causes earthquakes. If so, we should be able to test this claim scientifically. You all remember the homeopathy overdose?

Time for a Boobqauke.

On Monday, April 26th, I will wear the most cleavage-showing shirt I own. Yes, the one usually reserved for a night on the town. I encourage other female skeptics to join me and embrace the supposed supernatural power of their breasts. Or short shorts, if that’s your preferred form of immodesty. With the power of our scandalous bodies combined, we should surely produce an earthquake. If not, I’m sure Sedighi can come up with a rational explanation for why the ground didn’t rumble. And if we really get through to him, maybe it’ll be one involving plate tectonics.

So, who’s with me? I may be a D cup, but that will probably only produce a slight tremor on its own. If you’ll be joining me on twitter, use the tag #boobquake!

I think it would be good to post pictures to the facebook or twitter pages for scientific verification on the 26th, and to make sure to attend the event on Facebook, etc.

If you’re a skeptic woman, this is a good experiment. We’ll look for a significant increase in earthquake activity on April 26th to see if our immodesty pisses off God enough to tear the Earth apart in his jealous rage.

Again from Jennifer:

Dressing modestly won’t end earthquakes, so help out the victims of inevitable natural disasters at the Red Cross: http://www.redcross.org/

Our topic was:

Who We Admire in Science, Philosophy or Atheism and Why.

Update:

Ivy: Victor Frankl, author of Man’s Search For Meaning. His Logotherapy was about searching for a new and increased awareness in the present and enabling a new freedom and responsibility to act. The patient can then accept they they are not special and that their existence is simply coincidental, without destiny or fate. By accepting this, they can overcome their anxieties, and instead view life as moments, in which they are fundamentally free.

Daniel: Thomas Jefferson, the third president and a founding father. A freethinker and a great leader, he worked very hard to give America the separation of church and state. He was also opposed to a central bank, he was very insightful, and wanted to keep the power of the federal government in check.

Tim: John Shelby Spong is a retired bishop of the Episcopal church. He wrote Here I Stand: My Struggle for a Christianity of Integrity, Love, and Equality and followed the principle of the Episcopal seminary’s adage, “Seek the truth, come whence it may, cost what it will.” He revolutionized the Episcopal church.

Brent: August Weismann, Leonard Hayflick and Aubrey de Grey are three men in different biology fields who worked or work in life extension.

David: Richard and Mary Leaky who were doing great things in 1968, a book called African Genesis: A Personal Investigation into the Animal Origins and Nature of Man which helped David to seek a scientific basis to life, and Paul Monette who wrote Becoming a Man: Half a Life Story.

Neece: Carl Sagan and Richard Dawkins. Both great men who taught and teach critical thinking, skepticism, and make science attainable for anyone willing to look at how awesome the universe really is naturally. Sagan wrote quite a few books and so has Dawkins.

Butch: Frank Zappa and George Carlin, both men who were proponents of free speech and not letting yourself get crushed under the boot heel of religion or the government. Zappa was a part of the PMRC trials in the 80′s and Carlin was an outspoken critic of the church back in the 60′s before it was fashionable.

Gerald: Martin Gardner and James Randi. Gardner started the ball rolling in the 50′s with speaking out against creationism. He was a secular humanist. He wrote Did Adam and Eve Have Navels?: Discourses on Reflexology, Numerology, Urine Therapy, and Other Dubious Subjects and Fads and Fallacies in the Name of Science. James Randi is a big part of the skeptical movement, a part of CFI and the founder of the JREF (James Randi Educational Foundation). He has written many books.

Chad: Neil deGrasse Tyson is an astrophysicist who brings passion to science and scientific literacy. This video of a talk by Tyson from 2006 is about 38 minutes long. He talks about the god of the gaps throughout scientific history, intelligent design and then about Stupid Design. Highly recommended watching. Tyson has written several books.

Joe: Pearl S. Buck and the Freedom From Religion Foundation (FFRF). Pearl S. Buck took Joe out of his Ozzie and Harriet life and showed him other ways of life and different ways of thinking. Buck wrote many books. Here’s a quote from her about religion: “I feel no need for any other faith than my faith in the kindness of human beings. Like Confucius of old, I am so absorbed in the wonder of earth and the life upon it that I cannot think of heaven and angels.” The FFRF is a group that fights for the separation of church and state.

You may have noticed the tab under the banner that says Library. That lists all the books and media we each recommend. Feel free to contribute to it. In that list you’ll find that Tim recommended a book called  Don’t Sleep, There Are Snakes: Life and Language in the Amazonian Jungle by Daniel L. Everett. Brent found an interview on Groks Science Radio Show with the author.

Daniel has three stories to share:

The first is from RadioLab. Here’s the description from the page:

Parasites: What’s gotten into you? In this hour we explore nature’s moochers – the good, the bad, and the hideous. We have stories of lethargic farmers, zombie cockroaches, and even mind-controlled humans (kinda, maybe). Could parasites be the shadowy hands that pull the strings of life?
Carl Zimmer plays defense lawyer, trying to exonerate parasites for their wrongs, while Jad and Robert argue in defense of the victims. Our producer Lulu Miller comes in to moderate a lightning round of: “Parasites: are they evil, or are they awesome?” The parasites in question are the zombie wasp, the nematode, and the lovey-dovey blood fluke.

From NPR he sends a story about throwing out the Primordial Soup theory:

Is the “primordial soup” theory — the idea that life emerged from a prebiotic broth — past its expiration date?
Biochemist Nick Lane thinks so. The University College London writer and his colleagues argue that the 81-year-old notion just doesn’t hold water.
Lane tells NPR’s Guy Raz there’s another possible explanation for the emergence of life. But before we get to that, why toss out the soup theory?
Lane says the idea of a primordial soup goes back to 1929, and great biologists like J.B.S. Haldane.

And he shares another story from NPR about “mystical” baboons:

I’m not saying something magical happened. I can’t. Because I’m not a baboon.
And neither is Barbara Smuts, though she spent years in the field in East Africa studying baboons.
What Smuts saw one day in Africa while watching a troop of some 30 baboons is one of the more mysterious baboon tales ever. Her account was published in the Journal of Consciousness Studies a few years ago, and when I told the story to my co-host Jad Abumrad, on NPR and WNYC’s Radiolab, he was leery. He couldn’t explain what the baboons did, but when I proposed an explanation, he found it ridiculous.

The next two are from me (Neece):

How about an iron-plated snail? This little hydrothermal-vent-living creature was discovered in 1999. Scientists at MIT have been studying it. Here is the paper that they published. They write, “the shell is “unlike any other known natural or synthetic engineered armor.” It’s amazing

Life isn’t easy for the “scaly-foot gastropod”. This humble snail lives in hydrothermal vent fields two miles deep in the Indian ocean, and is surrounded by vicious predators. For example, there’s the “cone snail”, which stabs at its victims with a harpoon-style tooth as a precursor to injecting them with paralyzing venom. Then there’s the Brachyuran crab, which has been known to squeeze its prey for three days in an attempt to kill it. Yowsa.

Ah, but the scaly-foot gastropod has its own tricks. To fight back, it long ago evolved a particularly cool defense structure: It takes the grains of iron sulfide floating in the water around it and incorporates it into the outer layer of its shell. It it thus an “iron-plated snail”.

The other day Brent and I shared podcasts and radio shows with you. Well, I just found a new one! From Skepchick.org comes a new podcast called Curiosity Aroused. There’s one episode up now which is about calorie restriction for long life. It’s very interesting.

Why am I talking about nanotech on Darwin’s birthday? If you think about it, without evolution, we wouldn’t be able to manipulate our world so deftly and with such finesse. About 195,000 years ago homo sapiens first appeared in the fossil record. We started leaving Africa about 70,000 years ago, and migrated as far as the Americas 14,500 years ago.

A mere 10,000 years ago, we were mostly hunter-gatherers in nomadic groups. The first proto-states were developed only 6,000 years ago. Think of that! Look how far we’ve come in such a short time!

Think of how we lived just 100 years ago in 1910.

• By 1910 many suburban homes were wired up with power and new electronic gadgets.
• Vacuum cleaners and washing machines had just become commercially available, though still expensive for middle class folks
• The telephone was new, and millions of American homes were connected by manual switchboard
• People relied on the paper for their news, but radio technology was in its infancy
• The age of the airship was in full swing. Only 7 years previously, the Wright brothers had flown at Kitty Hawk
• Henry Ford introduced the Model T 2 years before and sold about 10,000 of them this year
• Advances in the use of gases meant the first electric refrigerators and air conditioning units.
• Neon lighting was debuted in Paris
• Inventions included: escalators, teabags, cellophane, instant coffee and disposable razor blades
• Women still had another 3 years of corsets

Things they didn’t have in 1910:

• stainless steel
• zippers
• the modern bra
• the modern band-aid
• the pop-up toaster
• sliced bread

But let’s get back to Liquid Glass. You spray it on. It’s transparent, non-toxic and can protect virtually any surface against almost any damage from hazards such as water, UV radiation, dirt, heat and bacterial infections. It’s flexible and breathable, which means it can be used on all kinds of products.

The liquid glass spray (technically termed “SiO2 ultra-thin layering”) consists of almost pure silicon dioxide (silica, the normal compound in glass) extracted from quartz sand. Water or ethanol is added, depending on the type of surface to be coated. There are no additives, and the nano-scale glass coating bonds to the surface because of the quantum forces involved. According to the manufacturers, liquid glass has a long-lasting antibacterial effect because microbes landing on the surface cannot divide or replicate easily.

Liquid glass was invented in Turkey and the patent is held by Nanopool, a family-owned German company. Research on the product was carried out at the Saarbrücken Institute for New Materials. Nanopool is already in negotiations in the UK with a number of companies and with the National Health Service, with a view to its widespread adoption.

The liquid glass spray produces a water-resistant coating only around 100 nanometers (15-30 molecules) thick. On this nanoscale the glass is highly flexible and breathable. The coating is environmentally harmless and non-toxic, and easy to clean using only water or a simple wipe with a damp cloth. It repels bacteria, water and dirt, and resists heat, UV light and even acids. UK project manager with Nanopool, Neil McClelland, said soon almost every product you purchase will be coated with liquid glass.

Food processing companies in Germany have already carried out trials of the spray, and found sterile surfaces that usually needed to be cleaned with strong bleach to keep them sterile needed only a hot water rinse if they were coated with liquid glass. The levels of sterility were higher for the glass-coated surfaces, and the surfaces remained sterile for months.

Other organizations, such as a train company and a hotel chain in the UK, and a hamburger chain in Germany, are also testing liquid glass for a wide range of uses. A year-long trial of the spray in a Lancashire hospital also produced “very promising” results for a range of applications including coatings for equipment, medical implants, catheters, sutures and bandages. The war graves association in the UK is investigating using the spray to treat stone monuments and grave stones, since trials have shown the coating protects against weathering and graffiti. Trials in Turkey are testing the product on monuments such as the Ataturk Mausoleum in Ankara.

The liquid glass coating is breathable, which means it can be used on plants and seeds. Trials in vineyards have found spraying vines increases their resistance to fungal diseases, while other tests have shown sprayed seeds germinate and grow faster than untreated seeds, and coated wood is not attacked by termites. Other vineyard applications include coating corks with liquid glass to prevent “corking” and contamination of wine. The spray cannot be seen by the naked eye, which means it could also be used to treat clothing and other materials to make them stain-resistant. McClelland said you can “pour a bottle of wine over an expensive silk shirt and it will come right off”.

In the home, spray-on glass would eliminate the need for scrubbing and make most cleaning products obsolete. Since it is available in both water-based and alcohol-based solutions, it can be used in the oven, in bathrooms, tiles, sinks, and almost every other surface in the home, and one spray is said to last a year.

Liquid glass spray is perhaps the most important nanotechnology product to emerge to date. It will be available in DIY stores in Britain soon, with prices starting at around £5 ($8 US). Other outlets, such as many supermarkets, may be unwilling to stock the products because they make enormous profits from cleaning products that need to be replaced regularly, and liquid glass would make virtually all of them obsolete.

A bit more info on it:

The flexible and breathable glass coating is approximately 100 nanometres thick (500 times thinner than a human hair), and so it is completely undetectable. It is food safe, environmentally friendly (winner of the Green Apple Award) and it can be applied to almost any surface within seconds . When coated, all surfaces become easy to clean and anti-microbially protected (Winner of the NHS Smart Solutions Award ). Houses, cars, ovens, wedding dress or any other protected surface become stain resistant and can be easily cleaned with water ; no cleaning chemicals are required. Amazingly a 30 second DIY application to a sink unit will last for a year or years, depending on how often it is used. But it does not stop there – the coatings are now also recognised as being suitable for agricultural and in-vivo application. Vines coated with SiO2 don’t suffer from mildew, and coated seeds grow more rapidly without the need for anti-fungal chemicals. This will result in farmers in enjoying massively increased yields.

…The really clever part is that there are no added nano-particles , resins or additives- the coatings form and bond due to quantum forces. Our research informs us that in all probability, we offer the most versatile coating in the world. This technology is now available for domestic use in Germany. Full scale retail availability in the UK will commence in early 2010.
