Bias amplification

Last week I had a frustrating exchange with an acquaintance over the safety of the COVID-19 vaccine.

He'd posted on social media a meme with the gist that there'd been so much waffling and we're-not-sure-ing by the medical establishment that you couldn't trust anything they said.  I guess he'd seen me post something just a few minutes earlier and knew I was online, because shortly afterward he DMd me.

"I've been waiting for you to jump in with your two cents' worth," he said.

I guess I was in a pissy mood -- and to be honest, anti-vaxx stuff does that to me anyhow.  I know about a dozen people who've contracted COVID, two of whom died of it (both members of my graduating class in high school), and in my opinion any potential side-effects from the vaccine are insignificant compared to ending your life on a ventilator.

"Why bother?" I snapped at him.  "Nothing I say to you is going to make the slightest bit of difference.  It's a waste of time arguing."

He started in on how "he'd done his research" and "just wasn't convinced it was safe" and "the medical establishment gets rich off keeping people sick."  I snarled, "Thanks for making my point" and exited the conversation.


It's kind of maddening to be told "I've done my research" by someone who not only has never set foot in a scientific laboratory, but hasn't even bothered to read peer-reviewed papers on the topic.  Sorry, scrolling through Google, YouTube, and Reddit -- and watching Fox News -- is not research.

Unlike a lot of anti-science stances, this one is costing lives.  Every single day I see news stories about people who have become grievously ill with COVID, and whose relatives tell tearful stories after they died about how much they regretted not getting the vaccine.  Today's installment -- from a man in Tennessee who has been in the hospital for three weeks and is still on oxygen -- "They told us not to worry, that it was just a bad cold.  They lied."

The problem is -- like my acquaintance's stubbornly self-confident "I've done my research" comment -- fighting this is a Sisyphean task.  If you think I'm exaggerating, check out the paper that came out this week in Journal of the European Economic Association, about some (actual, peer-reviewed) research showing that not only do we tend to gloss over evidence contradicting our preferred beliefs, when we then share those beliefs with others, our certainty we're right increases whether or not the people we're talking to agree with us.

The phenomenon, which has been called bias amplification, is like confirmation bias on steroids.  "This experiment supports a lot of popular suspicions about why biased beliefs might be getting worse in the age of the internet," said Ryan Oprea, who co-authored the study.  "We now get a lot of information from social media and we don't know much about the quality of the information we're getting.  As a result, we're often forced to decide for ourselves how accurate various opinions and sources of information are and how much stock to put in them.  Our results suggest that people resolve this quandary by assigning credibility to sources that are telling us what we'd like to hear and this can make biases due to motivated reasoning a lot worse over time."

I don't even begin to know how to combat this.  The problem is, most laypeople (and I very much include myself in this) lack the expertise to comprehend a lot of peer-reviewed research on immunology, which is usually filled with technical jargon and abstruse details of biochemistry.  And every step you take away from the actual research -- from university or research-lab press releases, to summaries in popular science magazines, to blurbs in ordinary media, to Some Guy's blog -- introduces more opinions, oversimplifications, and outright misinformation.

And I'm completely aware that Skeptophilia is also Some Guy's blog.  I will say in my own defense, however, that I do try to base what I write on the actual research, not on Tucker Carlson quoting Nicki Minaj's tweets about how her boyfriend got the COVID vaccine and afterward his balls swelled up.  (No, I am not making this up.)

So that's today's rather discouraging scientific study.  It's sad that so many of us have to become gravely ill, or watch someone we love die in agony, before we'll admit that we might have been wrong.  I'll just end with what the research -- from the scientists themselves -- has to say: the COVID vaccines are safe and effective, and the vast majority of people who have had severe COVID are unvaccinated.  The "breakthrough cases" of vaccinated people testing positive almost never result in hospitalization, and when they do, it's because of comorbidities.

But don't take my word for it.  If you honestly want to know what the research says, and you're willing to keep an open mind on the topic and shape your opinion based upon the evidence, start here.  And after that, go out and get the fucking vaccine.

Seriously.

 **************************************

London in the nineteenth century was a seriously disgusting place to live, especially for the lower classes.  Sewage was dumped into gutters along the street; it then ran down into the ground -- the same ground from which residents pumped their drinking water.  The smell can only be imagined, but the prevalence of infectious water-borne diseases is a matter of record.

In 1854 there was a horrible epidemic of cholera hit central London, ultimately killing over six hundred people.  Because the most obvious unsanitary thing about the place was the smell, the leading thinkers of the time thought that cholera came from bad air -- the "miasmal model" of contagion.  But a doctor named John Snow thought it was water-borne, and through his tireless work, he was able to trace the entire epidemic to one hand-pumped well.  Finally, after weeks and months of argument, the city planners agreed to remove the handle of the well, and the epidemic ended only a few days afterward.

The work of John Snow led to a complete change in attitude toward sanitation, sewers, and safe drinking water, and in only a few years completely changed the face of the city of London.  Snow, and the epidemic he halted, are the subject of the fantastic book The Ghost Map: The Story of London's Most Terrifying Epidemic -- and How It Changed Cities, Science, and the Modern World, by science historian Steven Johnson.  The detective work Snow undertook, and his tireless efforts to save the London poor from a horrible disease, make for fascinating reading, and shine a vivid light on what cities were like back when life for all but the wealthy was "solitary, poor, nasty, brutish, and short" (to swipe Edmund Burke's trenchant turn of phrase).

The necessity of safety

I suppose it's a good sign when what I write grabs me by the emotions and swings me around, and it bodes well for the story having the same effect on my readers.  There are a few scenes that make me choke up every time I read them -- one of which boils down to a single line of dialogue.

In the story, one of the main characters wakes up in the middle of the night to find that his partner, who has gone through some terrible emotional trauma, is crying silently, obviously trying not to wake him up.  He pulls his lover into a hug and whispers, "Go ahead and cry if you need to.  I've got you.  You're safe in my arms."

What got me thinking about this scene is a conversation I had with some online writer friends, one of whom asked the provocative and fascinating question, "How could you tell someone 'I love you' without using those words?"  My immediate response was "You are safe."  Those words resonate with me for a great many reasons, not least because I virtually never felt safe as a child or young adult.  Everything around me always seemed precarious -- I spent the first half of my life feeling like I was a tightrope walker, always a single misstep from utter ruin, and because of that needed to be constantly vigilant and wary.

It was exhausting.

The pragmatists in the audience might point out that in reality none of us are safe, and technically they'd be right.  Bad stuff can happen any time, for any reason or no reason at all, and as the line from Fight Club says, "On a long enough timeline, the survival rate for everyone drops to zero."  But still, that feeling of safety and security, that there's someone looking out for you and that your friends have your back, is pretty critical for our emotional health.

These days, a sense of safety is hard to find.  We're still in the midst of a pandemic, trying to guard ourselves against an invisible enemy that can jump from one person to another with frightening speed.  Here in the United States almost a half a million people have died of COVID, and countless others have become desperately ill with complications lasting for months.  Everywhere people are losing their jobs, businesses closing down, schools going entirely virtual.  Health care workers are facing the awful double-whammy of dealing with incredible overwork and the fact that despite their best efforts, some of their patients aren't going to survive.  Add to all that the fact that in many parts of the world we've seen unprecedented social unrest, with deep-seated hatred and prejudice bubbling up nearly everywhere -- and its victims are often people who just happen to be in the wrong place at the wrong time.

Security is in very short supply lately.

Three separate studies conducted late last year track the outcome.  The United States Center for Disease Control, Boston University, and Johns Hopkins University independently found that the incidence of anxiety, severe depression, and serious psychological distress has tripled since the start of the pandemic.  Unsurprisingly, the effect was larger in vulnerable populations -- low-income individuals, minorities, people with prior mental health issues, people who have lost friends or family members to COVID.  Most alarming, young adults across the board showed skyrocketing incidence of emotional distress -- the CDC study found that almost two-thirds of the people from eighteen to twenty-four who participated in the study reported experiencing severe depression since the outbreak started, a quarter reported greater use of alcohol or drugs to cope with the stress, and a quarter said they'd seriously considered suicide in the last thirty days.

This is horrifying and alarming.  We already had a built-in mental health crisis ongoing because of the stigma of mental illness and our society's unwillingness to radically revamp the way it's monitored, treated, and covered by insurance.  COVID has taken a dreadful situation and made it much, much worse, and I fear the repercussions will far outlast the pandemic itself.

The worst part is that the nature of the pandemic has taken away the one thing that can make emotional distress bearable; comfort from our friends and loved ones.  I was talking with some friends (online, of course) a few days ago about what we miss most from the pre-pandemic days, and one that came up over and over was "long hugs from friends."  I'm terribly shy by nature, but that one was spot-on.  Even we introverts are struggling with the isolation.

Unfortunately, it looks like we are going to be going without long hugs from friends for quite some time, and that means we need to be especially assiduous about looking out for each other.  Check in with the people you care about, especially the ones who don't seem to need it, who are used to being the strong, secure, competent ones who put everyone else's needs in front their own.  Okay, we can't have the level of physical and emotional real-time contact we had before, but we can do things to compensate -- Zoom or Skype visits, phone calls, even something simple like a text message saying, "Hi, I was thinking about you.  How are you doing?"

In times like these we have to lean on our friends -- and let our friends lean on us.  Be honest about what you're feeling, and reassure yourself that right now we're pretty much all feeling that way.  If you're having a hard time coping, let the people you love know rather than suffering in silence.  If you are really at the end of your tether, get on the phone -- the suicide prevention hotline is 1-800-273-8255.  There's help to be had if you are willing to reach out for it.

We'll get through this, but if we're to come through as unscathed as possible, it will be because we've banded together and helped each other through.  Don't be afraid to show others you're hurting; it's how you'll get past this horrible low point.

And don't be afraid to tell your friends and loved ones, "Go ahead and cry if you need to.  I've got you."  It may be a while before we can back it up with a long hug, but for now, it's the best we can do.

************************************

Science fiction enthusiasts will undoubtedly know the classic 1973 novel by Arthur C. Clarke, Rendezvous with Rama.  In this book, Earth astronomers pick up a rapidly approaching object entering the Solar System, and quickly figure out that it's not a natural object but an alien spacecraft.  They put together a team to fly out to meet it as it zooms past -- and it turns out to be like nothing they've ever experienced.

Clarke was a master at creating alien, but completely consistent and believable, worlds, and here he also creates a mystery -- because just as if we really were to find an alien spacecraft, and had only a limited amount of time to study it as it crosses our path, we'd be left with as many questions as answers.  Rendezvous with Rama reads like a documentary -- in the middle of it, you could easily believe that Clarke was recounting a real rendezvous, not telling a story he'd made up.

In an interesting example of life imitating art, in 2017 astronomers at an observatory in Hawaii discovered an object heading our way fast enough that it has to have originated outside of our Solar System.  Called 'Oumuamua -- Hawaiian for "scout" -- it had an uncanny, if probably only superficial, resemblance to Clarke's Rama.  It is long and cylindrical, left no gas or dust plume (as a comet would), and appeared to be solid rather than a collection of rubble.  The weirdest thing to me was that backtracking its trajectory, it seems to have originated near the star Vega in the constellation Lyra -- the home of the superintelligent race that sent us a message in the fantastic movie Contact.

The strangeness of the object led some to speculate that it was the product of an extraterrestrial intelligence -- although in fairness, a team in 2019 gave their considered opinion that it wasn't, mostly because there was no sign of any kind of internal energy source or radio transmission coming from it.  A noted dissenter, though, is Harvard University Avi Loeb, who has laid out his case for 'Oumuamua's alien technological origin in his new book Extraterrestrial: The First Sign of Intelligent Life Beyond Earth.

His credentials are certainly unimpeachable, but his book is sure to create more controversy surrounding this odd visitor to the Solar System.  I won't say he convinced me -- I still tend to side with the 2019 team's conclusions, if for no other reason Carl Sagan's "Extraordinary Claims Require Extraordinary Evidence" rule-of-thumb -- but he makes a fascinating case for the defense.  If you are interested in astronomy, and especially in the question of whether we're alone in the universe, check out Loeb's book -- and let me know what you think.

Put down the ducky

Yesterday, we looked at the fact that scientists have actually not admitted that vaccines cause autism.  Today, we consider the fact that your child's rubber duck is not going to kill them, either.

You'd think this would be unnecessary, but in this time of fearmongering and sensationalism, no claim is too outlandish to gain traction as long as it plays on someone's anxiety.  In this case, the whole thing started with a paper in Nature called, "Ugly Ducklings—The Dark Side of Plastic Materials in Contact With Potable Water," by Lisa Neu, Carola Bänziger, Caitlin R. Proctor, Ya Zhang, Wen-Tso Liu, and Frederik Hammes, which found that after several uses, plastic bath toys were covered with bacteria (including fecal coliform bacteria) and various species of fungi.

When I read the paper, my general response was, *yawn*.  Of course bath toys are covered with bacteria.  Everything is.  Add to that the fact that (1) bath water is warm, (2) tubs are generally not spotless to start with, and (3) the bath-taker is immersing his or her naked body into the water with the purpose of washing dirt off, it's no wonder bath water is a soup of various bacteria.

Even fecal coliforms.  Because, I hope, we all periodically wash our butts, too.

But there were people who stumbled on this paper, with its alarming-sounding title (which, as scientific researchers, Neu et al. should have known better than to give it), and immediately interpreted the study as implying that rubber duckies posed a deadly danger to children.  Bacteria!  Oh no!  Must immediately throw away all bath toys!

Let's just clear up a few things, here.

Even in a healthy human, the number of bacterial cells in or on you exceeds the number of human cells you have.  You read that right; a study way back in 1977 estimated about 39 trillion bacterial cells in or on a typical human, significantly outnumbering the 30 trillion human cells you have (84% of which are red blood cells).  More to the point, the vast majority of these bacteria are either neutral or actively helpful; disturbances in the "intestinal flora" are thought to have roles in such horrible diseases as Crohn's disease, peptic ulcers, CDiff (Clostridium difficile) infection, and ulcerative colitis.  (Which is why there is a promising therapy to treat those using -- I kid you not -- fecal transplants from a healthy individual, to reestablish the right intestinal flora.)

So if your rubber ducky is coated with bacteria, the fact is, so are you.  And most of us are still healthy most of the time.

But that logic evidently wasn't sufficient; there have been various alarming articles on "alternative-medicine" and "natural parenting" sites claiming that not only were bath toys deadly, but there was a systematic coverup of the research, presumably sponsored by Big Ducky.

The whole thing was debunked roundly by Alex Berezow over at the website of the American Council on Science and Health last week.  Berezow went even further with regards to the Neu et al. study; he claimed that they were actively seeking an alarmist reaction for the purposes of publicity:
Amazingly, the authors cite mommy blogs and the sensationalist book Slow Death by Rubber Duck: The Secret Danger of Everyday Things in their paper.  The book is about the dangerous "chemicals" that are poisoning everybody, a chemophobic tactic that we've debunked over and over again. 
Quite honestly, I don't think I've ever seen anything like this in my professional career. Serious scientists don't cite mommy blogs and sensationalist popular science books in peer-reviewed journal papers. 
The authors had a clear strategy in mind: (1) Do a study on a common household object; (2) Produce boring data that doesn't surprise any microbiologist; (3) Write a provocative, fearmongering headline; (4) Market it to a gullible, clickbait-hungry press (like the New York Times), who would repeat their claims without any criticism or critical thinking; and (5) Watch the media interview requests and grant dollars come rolling in. 
Mission accomplished.  The deceitful manipulation of the press for their own professional benefit would be a thing of fascination if it wasn't so utterly disgusting.
And I have to admit he's got a point.

Of course, the craziest thing about the Natural Organic Health people who started running around in circles flailing their arms and making alarmed little squeaking noises after reading the study is that they apparently never thought of the simplest expedient for dealing with the situation if you're worried: wash the fucking toys.  I mean, seriously.  If you think there are nasty bacteria on the rubber duck, scrub it with a little soap and water after your kid's done in the bath.  Or, if you really want to go crazy, wipe it off with some rubbing alcohol.

VoilĂ .  If not no bacteria -- there nothing that could do that, short of an autoclave, which would turn your bath toys into a puddle of brightly-colored melted plastic -- at least there'll be fewer.

All of this goes to show that if there's nothing to be scared of, people will find something.  Added to the problem that (if Berezow is right about Neu et al. being guilty of deliberate sensationalization) fearmongering sells.  So if you like playing with a rubber ducky in the tub, have at it.  I hear you have to put it down if you want to play the saxophone, but other than that, it's perfectly safe.

Safety shift

It's simultaneously amusing and a little frightening how sure we all are of our own opinions.

When challenged, we tend to react either with incredulity or with anger.  How on earth could anyone believe differently than we do?  Our own beliefs arise, of course, from a careful consideration of the facts, of the world as it is.  If you think differently, well, you're just not putting things together right.

And not only do we use our certainty in our own rightness to make judgments about others, we also use it to cement our own conclusions over time.  I recall with some discomfort the time I was being interviewed on a radio program, and the host asked me a perfectly legitimate question for someone who is a self-styled skeptic, namely: has there been a time that I have been challenged in one of my beliefs, and after analysis, turned out to be wrong?

Well, it was a fair knock-out.  I could only recall one time that, in the (then) five years I'd written Skeptophilia, that a reader had posted an objection that changed my mind.  (If you're curious, it was about the efficacy of low-level laser therapy on wound healing; she came at me with facts and data and sources, and even if I'd been inclined to argue, I had no choice but to admit defeat and retreat in disarray.)

But other that that?  When I get objections, I tend to do what most of us do.  Say, "Oh, how sad for you that you don't agree with me," and forthwith stop thinking about it.

What's so appalling about this is how easily those seemingly set-in-stone root beliefs can be changed by circumstances outside of our control, and often, without our even knowing it's happening.  Which brings me to a simple but elegant experiment done at Yale University by John Bargh, Jaime Napier, Julie Huang, and Andy Vonasch that appeared in the European Journal of Social Psychology late last year.  The experiment springboarded off a longitudinal study done at the University of California that showed that the more fear a child expressed over novel situations in a laboratory at age four, the more conservative (s)he was likely to be twenty years later.  Conservatives, it has been found, are more likely to regard the unfamiliar with suspicion, and in fact, have higher activity in the amygdala, a part of the brain associated with anxiety.  Liberals, on the other hand, have a greater degree of trust in the unknown (whether justified or not), and tend to be less fearful of new people and new experiences.

So what Bargh et al. decided to do was to see if the opposite might hold true -- if changing people's sense of being safe would alter their political stances.

[image courtesy of the Wikimedia Commons]

And they did.  Bargh's team guided participants through an intense visualization exercise, which for some participants was about having the ability to fly, and for others being invulnerable and safe from harm in all situations.

The results were dramatic.  In Bargh's words:
If they had just imagined being able to fly, their responses to the social attitude survey showed the usual clear difference between Republicans and Democrats — the former endorsed more conservative positions on social issues and were also more resistant to social change in general. 
But if they had instead just imagined being completely physically safe, the Republicans became significantly more liberal — their positions on social attitudes were much more like the Democratic respondents.  And on the issue of social change in general, the Republicans’ attitudes were now indistinguishable from the Democrats.  Imagining being completely safe from physical harm had done what no experiment had done before — it had turned conservatives into liberals.
This study has a couple of interesting -- and cautionary -- outcomes.

First, the researchers did not look at how long-lasting these changes were, so even for those who think the changes were a good thing (probably my left-leaning readers), there's no guarantee that the leftward shift was permanent.  Second, consider the fact that the shift occurred by having people visualize an imaginary scenario -- i.e., something that isn't true.  Even if the shift was long-lasting, I have some serious qualms about changing people's beliefs based on having them imagine a falsehood.  That, to me, is no better than having them persist in erroneous beliefs because of a lack of self-analysis.

But to me the scariest result of the experiment by Bargh et al. is to consider how this tendency is exacerbated -- or, more accurately, manipulated -- by the media.  Conservative news sources thrive on inducing fear.  (As one example, think about the yearly idiocy over at Fox News about we atheists' alleged "War on Christmas.")  By the same token, liberal media tends to focus on stories that make you feel better, at least about the usual left-wing talking points -- stories, for example, of immigrants who have succeeded and become model citizens.  In both cases, it's powered by our tendency to shift rightward when we feel threatened and leftward when we feel safe -- and, in both cases, to keep listening to the news sources that reinforce those feelings.

I'm not at all sure what to do about this, or honestly, if there's anything that can be done.  We all have our biases in one direction or the other to start with, and we're pretty likely to seek out news sources that corroborate what we already thought.  A combination of confirmation bias and the echo-chamber effect.  But what the Bargh et al. study should show us is that we can't become complacent and stop considering our own beliefs in the sharpest light available -- and always keep in mind the possibility that our own opinions might not be as carved in stone as we'd like to think.

Fact-free zone

It's a theme that has cropped up over and over here at Skeptophilia; the fact that people spend a lot more time reacting from emotion than they do from rational thinking.

But the fact of its being familiar doesn't mean it's not maddening.  Which is why I responded to a recent paper that appeared in Perspectives on Psychological Science a couple of days ago with a wince and a facepalm.

Entitled "Evidence for Absolute Moral Opposition to Genetically Modified Food in the United States," and written by Sydney E. Scott and Paul Rozin of the University of Pennsylvania and Yoel Inbar of the University of Toronto, the paper had the following depressing conclusion:
Public opposition to genetic modification (GM) technology in the food domain is widespread (Frewer et al., 2013).  In a survey of U.S. residents representative of the population on gender, age, and income, 64% opposed GM, and 71% of GM opponents (45% of the entire sample) were “absolutely” opposed—that is, they agreed that GM should be prohibited no matter the risks and benefits.  “Absolutist” opponents were more disgust sensitive in general and more disgusted by the consumption of genetically modified food than were non-absolutist opponents or supporters.  Furthermore, disgust predicted support for legal restrictions on genetically modified foods, even after controlling for explicit risk–benefit assessments.  This research suggests that many opponents are evidence insensitive and will not be influenced by arguments about risks and benefits.
Catch that?  45% of the people surveyed think that GMOs should be illegal regardless of the risks or benefits.  In other words, regardless of the evidence.  Apparently, a little under half of the respondents could be presented with persuasive evidence that GMOs are risk-free and have proven benefits, and they still would be against them.


It's a discouraging finding.  There are a great many issues facing us today that drive an urgent need to make smart decisions.  We need to be making those decisions based on facts and logic, not on knee-jerk gut response and inflammatory rhetoric.  Climate change, policy on vaccines, regulation of alternative medicine, even the oversight of public education -- how can we do what's right if we're making decisions irrespective of the facts?

Of course, part of the problem is that even people with access to the facts often don't know the facts.  Witness the study released last week in the Journal of the Federation of American Societies for Experimental Biology that showed that 80% of respondents wanted to have laws mandating labeling identifying all foods that contain DNA.

Yes, you read that right.  Not genetically modified DNA; DNA, period.  To make it even worse, 33% of the respondents thought that non-genetically-modified tomatoes "did not contain genes," and 32% thought that "vegetables do not contain DNA."  As Katherine Mangu-Ward put it over at Reason.com, "When it comes to genetically modified food, people don't know much, they don't know what they don't know, and they sure as heck aren't letting that stop them from having strong opinions."

The problem is, the people who shriek the loudest tend to be the ones with the least comprehension of science.  Senator James Inhofe, who for some baffling reason is the chair of the Committee on Environment and Public Works, thinks that holding up a snowball disproves anthopogenic climate change.  The alt-med/anti-vaccine crowd still believe Andrew Wakefield's discredited study linking vaccinations to autism, despite overwhelming research demonstrating that there is no connection -- and anyone who argues otherwise is said to be "a shill for Big Pharma."  (Makes me wonder when my first Shill Check is going to arrive.  Soon, I hope.  I could use the money.)

Only rarely does anyone look at the evidence and say, "Oh.  Okay.  I guess I was wrong, then."  And the paper by Scott et al. seems to support the contention that if I'm waiting for this to happen, I better not be holding my breath.

Of course, along with resistance to change, another natural human inclination is the whole "Hope Springs Eternal" phenomenon.  So I'm not giving up on blogging, at least not any time soon.  Despite the rather dismal conclusion of the recent research, I'm still hopeful that we can make change, incrementally, by picking away wherever we can.

Food fight

There's a logical fallacy I've seen a lot lately.  It's called argumentum ad Monsantum (also known as argumentum ad Hitlerum).  The idea is that you can immediately cast doubt on the motives of a person or organization if you compare them to, or (worse) claim they got their ideas from, a stand-in for The Boogeyman.  Monsanto, Hitler, communists, Muslims, whatever one seems apt at the time.

Of course, this boils down to lazy thinking, which most of the fallacies do.

What's rather maddening about this is that the opposite can happen, too.  Give something an association with a name that's considered positive, and you automatically reap the benefits of a reflected glow of goodness, whether or not it's deserved.

You could call this the Compare-Yourelf-To-Mother-Teresa-And-Declare-Victory ploy.

The argumentum ad Monsantum strategy has been much used in the fight against GMOs, since Monsanto has been heavily involved in developing genetically modified crops for years.  How anyone who has even a smidgen of a background in science can fall for this is beyond me; comparing RoundUp-Ready Wheat with late blight-resistant potatoes makes no sense from any standpoint, from effects on human health to ecological impact.  (Consider that the former results in an increase in the use of chemical pesticides, and the latter decreases it.)

Saying that all GMOs are bad is, in fact, precisely equivalent to claiming that all genes do the same thing.

What's wryly amusing about this is that the opposite side of the same coin -- the word organic -- is maybe not as squeaky-clean as it's been billed.  The reputation of organic produce for containing less in the way of Nasty Chemicals is apparently ill-deserved, considering a story by David Zaruk over at The Risk-Monger that revealed a startling fact -- that organic farmers in the United States are certified to use three thousand substances that are designated as toxic, and that are considered acceptable purely because they're "natural."

Copper sulfate, used as a fungicide, is highly toxic to fish, and is completely non-biodegradable.  Pyrethrin and azadirachtin (neem oil), insecticides that come from plants and therefore are somehow thought to be better than synthetics, are lethal to honeybees and carcinogenic in humans.  Rotenone, from the leafy parts of the jicama plant, kills damn near everything you put it on.

Also on the list is nicotine.  Made, presumably, from all-natural, organic, health-supporting tobacco plants.

Worse still, once produce is certified organic, it bypasses any kind of requirement for pesticide residue testing.  Because organic produce isn't supposed to have any pesticides on it, right?

Of course right.

Monsanto = bad.  GMO = bad.  Organic = good.  All a way to give yourself a nice warm feeling of being socially and environmentally responsible, not to mention healthy, and then to stop thinking.  Myself, I would rather the responsible use of synthetic fertilizers and pesticides, which comes along with mountains of information on hazards and requirements for residue testing, than giving free rein to people who believe that Natural Must Mean Good For You.

Now, don't get me wrong; I think that a lot of the organic food movement is driven by the right motives.  Creating our food with as little negative environmental impact as possible, and producing food that is healthy and nutritious, are certainly goals to be lauded.  What is unclear is whether the rules governing organic food production as they now exist are meeting those goals.

But the beat goes on, which is why there was an apparently serious article over at The Organic Authority wherein we learn that artist and practitioner of magic Steven Leyba is mounting a one-man campaign against Monsanto, spurred by his own personal health experiences:
In 2010 I had been overweight and decided to get healthy.  I started eating large amounts of fruits and vegetables from my local grocery store.  I got sick and that was the time I found out about GMOs.  I was appalled.  I couldn’t understand why I would get so sick by eating what I thought was so healthy.  When I switched to organic food I got healthy again.
And since anecdote with a sample size of one is apparently data, Leyba decided to take matters into his own hands, and is launching a magic spell against Monsanto:
Death curses work like any manifestation of will like Gestalt psychology; you visualize and act in accordance and at some point what you can conceive and believe you can achieve.  Medicine men practice this and even medical doctors to some extent practice this.  They plant suggestions in people’s minds for healing and those people start to do things that promote their own healing.  For me I see a great need to identify the cancer (Monsanto and NestlĂ©) and attack with full force and mirror back this so-called Black Magic they are doing to all of us.
So he made a book full of disturbing imagery that includes demented portraits of executives who work for Monsanto, and also Supreme Court Justice Clarence Thomas, who worked as an attorney for Monsanto in the 1970s.  

"I encourage everyone to Death Curse Monsanto and NestlĂ©," Leyba says.  "Justifiable Death Curses are effective on many levels, fun, cathartic... and completely legal."

Article author Jill Ettinger, far from casting a wry eye at Leyba's Eye Of Newt approach to taking down Monsanto, seems to think it's a great idea.  And given the recent push in the United States for mandatory labeling of GMOs, "it may just be working," she says.

No harm, I suppose, if it amuses him.  But wouldn't it be better to learn some actual science, rather than giving in to fear talk and ignorance?  Not to mention (literal) magical thinking?

The world is complex, and when the motives of people and corporations get involved, it becomes even worse.  It'd be nice if categorical thinking really worked.  The difficult truth is, if you want to give yourself the best shot at making smart choices for yourself, both with respect to your personal health and the environmental impact, there's no substitute for bypassing the hype on both sides and understanding the reality beneath it all.

Giving up on convincing the pigeons

The furor over vaccinations has a long history.

The history, which is intensely frustrating to people like me who think that the anti-vaxxers' rhetoric borders on deliberate endangerment of people's lives, seems always to play out the same way.  In 1998, the now-infamous Dr. Andrew Wakefield published a study in Lancet claiming that there was a connection between the MMR vaccination and autism.  The study turned out to involve only twelve patients, so there was a bias right from the beginning that was so big you could drive a tanker truck through it.  When you add the investigation by Brian Deer that uncovered the fact that Wakefield was being subsidized by a group of lawyers who were conspiring to file lawsuits against vaccine manufacturers, then... well, you get the picture.

The British Medical Journal called Wakefield's study "fraudulent."  Ten of the twelve authors of the Wakefield paper formally withdrew their support in 2004, stating, "We wish to make it clear that in [the 1998] paper no causal link was established between MMR vaccine and autism as the data were insufficient.  However, the possibility of such a link was raised and consequent events have had major implications for public health.  In view of this, we consider now is the appropriate time that we should together formally retract the interpretation placed upon [the] findings in the [1998] paper, according to precedent."

None of that mattered.  The anti-vaccination movement was off and running.  A claim was made that thimerosal, a mercury-based preservative in many vaccines, was what was causing the link between vaccines and autism (which was based on a fraudulent claim from the beginning, remember?).  Many governments caved to the hype, removing thimerosal, which had been used safely since the 1930s.  Surprisingly enough, the rates of autism were unaffected.

That apparently didn't matter, either.

Then the claim started running about that getting "natural" diseases was better for your immune system than getting "artificial" vaccines.  Apparently the idea was that getting diseases was like lifting weights for the immune system.  In 2002, the American Institute of Medicine sponsored a study to see if this was true.  They found no support for it.

Guess what effect this had on the anti-vaccination movement?

Further studies tried to find a link between vaccination and multiple sclerosis, ALS, diabetes, rheumatoid arthritis, and sudden infant death syndrome.  Yup... no connection.  So the anti-vaxxers decided that some children were more sensitive to vaccines, and the studies hadn't taken that into account.  Other, more extreme spokespeople for the movement started claiming that the researchers, not to mention all the doctors and nurses, were shills for "Big Pharma."  "Big Pharma," they say, wants to keep people sick (or worse, make people sick) in order to keep making profits.  And people like me, who object to policy being driven by folks who evidently have no understanding of how science and peer review are done, are just plain stupid.

But the research continued to pile up, and always in favor of the safety of childhood vaccination.  So the anti-vaxxers shifted the goalposts again.  Now they went after gardasil, the vaccine against HPV, a virus shown to be one of the main triggers for cervical, oropharyngeal, vaginal, and anal cancer.  So that was studied.  Once again: the vaccine is safe and effective.  Any side effects are extremely uncommon, and the risk is far lower than the risk of contracting the virus and eventually developing cancer.  But the claims continued to circulate; I've heard more than one parent say, "I'm not having my kid get the HPV vaccine!  It's too risky!"

So more studies were done.  No connection continued to be found.  And just last week, a study was published in the Journal of the American Medical Association showing that in a study of 95,000 children, there was no link between vaccinations and autism -- being vaccinated doesn't alter the risk even in children who have a higher risk of autism from other factors.

An article about the study in Vocativ states that "this should end the debate once and for all."  But it won't.  You know why?

This is not a debate.  This is people who understand science trying to argue with alarmists who believe every damn thing a celebrity says, over the advice given by medical researchers.  This is playing chess with a pigeon -- no matter how cleverly you play, the pigeon just shits all over the chessboard and then struts around like it won.

This should have been over, as a discussion, twenty years ago.  Eliminating vaccines is dangerous and irresponsible.  The childhood diseases of the pre-vaccine period are not mild tummy aches; kids died of them.  Lots of kids.  But you know why the anti-vaxxers don't recognize that?  Here's why.

No one in the United States remembers how horrific these diseases are.  Hardly anyone dies of them any more, because nearly everyone has had the fucking vaccine.  Measles is not just "a bunch of spots," it causes sky-high fever that can leave a child deaf or permanently brain damaged.  Mumps can cause sterility, especially in young men.  Diphtheria kills you by slow suffocation.  Typhoid gives children such serious vomiting and diarrhea that they can die of dehydration, not to mention getting lovely symptoms like intestinal hemorrhage.

Vivid enough mental images for you?

Some people do change their views, but it often takes being walloped by a metaphorical two-by-four for it to happen.  Last month there was the highly publicized story of a mom from Ottawa who was an outspoken anti-vaxxer, but changed her tune after all seven of her unvaccinated children simultaneously contracted whooping cough.

Wouldn't it be nice if people could be convinced by evidence and logic, and not by their children being at risk of dying?

So my general opinion is that if the research we already had hasn't convinced people, further research won't, either.  It's time we stop wasting resources on these people.  The evolutionary biologists learned that long ago; you don't see them doing research and publishing papers to demonstrate over and over again that the Earth is not six thousand years old.  We need to treat the anti-vaxxers as what they are -- the young-earth creationists of the medical world.

And mandate that children be vaccinated, nationwide.  No exemptions, sorry.

This discussion is over.

Fluid morality

I try not to let my skepticism slide over into cynicism.  The latter, a disbelieve-everything-they-say approach, seems to me to be as fundamentally lazy as gullibility.  Being a skeptic is harder, but ultimately more likely to land you near the truth; keep your mind open, wait for hard evidence, and then follow that wherever it leads.

But there are some realms in which I am reminded of Lily Tomlin's line, "No matter how cynical I get, it's just not enough to keep up."  And one of those is the way fracking is being presented by the powers-that-be.

Consider the highly publicized publicity stunt by Colorado Governor John Hickenlooper, who in 2013 drank a glass of fracking fluid to show how safe it was.

"You can drink it," Hickenlooper told the Senate Committee on Energy and Natural Resources.  "We did drink it around the table, almost rituallike, in a funny way.  It was a demonstration… they’ve invested millions of dollars in what is a benign fluid in every sense."

The gas companies have stated outright that the ingredients are "sourced from the food industry," but still refuse to give a complete formulation for how it's made, saying such information is "proprietary."  Hickenlooper agrees, and said, "If we were overzealous in forcing them to disclose what they had created, they wouldn’t bring it into our state."

Under pressure from environmental groups, the gas industry has released a list of "the chemicals used most often" in fracking fluid, along with their purpose.  They state that "there are dozens to hundreds that could be used as additives" above and beyond these, although this is downplayed.

They look like they're doing everything they can to be completely transparent, up to the point where it starts to jeopardize their trade secrets.  "Here, we'll show you what we're doing!" they seem to be saying.  "You want the water supply protected, and safety to be paramount?  Well, so do we!"

Then you have to wonder why the industry has not rushed into the breach when people have been injured by the chemicals in their "benign" fracking fluid.  Makes you almost think they're... covering something up.

In 2008, a gas driller, Clifton Marshall, came into the emergency room in Durango Mercy Regional Medical Center in Durango, Colorado, after he had spilled fracking fluid on his clothes and boots.  Marshall was in a bad way, but it didn't end there; Cathy Behr, an emergency room nurse, spent ten minutes working on Marshall without using adequate protective equipment.  By this time, the emergency room had to be cleared because the smell of the chemicals was strong enough to make people gag.  But Behr, who had come into direct contact with the contaminated clothing, was to experience worse.  Two days later, the nurse found herself back in the emergency room, but this time because she was sick; she had jaundice, and was vomiting and feverish.  The doctors found that Behr was in multiple organ failure from "poisoning by an unknown chemical."

Pressed by the hospital to tell them what was in the fracking fluid that sickened Behr and Marshall, the gas company -- Halliburton Industries -- refused, saying it was a trade secret.  If anyone released what was in the fluid, they said, they would sue -- and then pull their multi-million-dollar drilling operation from the state.

Hospital officials backed down.  To this day, no one knows what was in the fluid.

In a rural community in Pennsylvania -- no one knows exactly where, for reasons you'll see in a moment -- the owners of a 300-acre dairy farm signed a land-use agreement with a gas company, allowing fracking on their land.  The disturbance would be minimal, the gas company said, and the risk slight.  After the drilling began, though, the family who owned the farm, the "Rogers" family (not their real name), began to question the effects that the operation was having on their drinking and agricultural water, and agreed to participate in a study by an independent agency to monitor what was happening.

But they couldn't do that, they found out quickly.  Here's how TruthOut reported the story:
The Rogers did not realize they had signed a nondisclosure agreement with the gas company making the entire deal invalid if members of the family discussed the terms of the agreement, water or land disturbances resulting from fracking and other information with anyone other than the gas company and other signatories... 
Mrs. Rogers initially agreed to participate in a study Perry [the scientist coordinating the study] was conducting on rural families living near fracking operations. She later called Perry in tears, explaining that her family could no longer participate in the study because of the nondisclosure clause in the surface-use agreement. She told Perry she felt stupid for signing the agreement and has realized she had a good life without the money the fracking company paid them to use their land.
There are also dozens of cases where gas companies have been sued because their operations have permanently contaminated drinking water supplies, and have settled in the litigants' favor -- but only on the condition that the litigants sign a statement mandating that they never disclose what the gas companies did.  This is an easy out for the gas companies; people will usually settle for an amount of cash that the gas industry considers a pittance as compared to the bad press they'd receive if such information became public.  "At this point they feel they can get out of this litigation relatively cheaply," Marc Bern, an attorney with Napoli Bern Ripka Sholnik LLP in New York, who has negotiated on behalf of homeowners, said in an interview.  "Virtually on all of our settlements where they paid money they have requested and demanded that there be confidentiality."

There are also multiple cases where doctors have appealed to gas companies to release what is in fracking fluid, to allow the doctors to treat patients poisoned by exposure to it, and the industry has complied -- but only if the doctors themselves agree to a lifelong nondisclosure statement.

And state governments are caving in from the pressure by the industry.  Just last year, North Carolina passed a bill that made it a crime for anyone to disclose the constituents of fracking fluid.  The name of the bill?  The "Energy Modernization Act."

Still think that the gas companies are all about safety and transparency?  Then consider one more story, again from southwestern Pennsylvania, only two years ago.

Chris and Stephanie Hallowich lived with their two children, then 7 and 10, in a house in rural Washington County, when they started experiencing health issues from water that had been fouled by a fracking operation nearby.  They were desperate to get out of their house, and sued the gas company, Range Resources, for enough money to cut their losses and move.  Range Resources agreed to a $750,000 settlement, but required (guess what?) a nondisclosure agreement.  The Hallowichs could not speak to anyone about fracking, or the Marcellus Shale, or Range Resources, or their symptoms, or the contamination to their water supply, ever.

And that lifelong gag order also applied to their children.

The Hallowichs' attorney, Peter Villari, said directly to Washington County Common Pleas Court Judge Paul Polonsky, who heard the case, "I, frankly, your Honor, as an attorney, to be honest with you, I don’t know if that’s possible that you can give up the First Amendment rights of a child."  Pozonsky didn't have an answer to that except that this is what the Hallowichs had to agree to if they wanted to settle.

"That someone would insist on confidentiality of a minor child," Villari said, "or that it would be discussed within the context of a proposed settlement was unusual.  I have not encountered it before and I have yet to encounter it again."

"Unusual" isn't the word I'd use.  I think "unconstitutional" comes closer to the mark.

The frightening part of this is that because the gas industry is wealthy and powerful, they are pulling the strings here -- and everyone else is dancing to their tune.  They have no reason to bend.  They've been getting their own way at every turn, from politicians and courts that conveniently ignore the dangers to ordinary citizens because (frankly) money talks.

Where this skein of lies comes full circle, though, is in asking why the gas companies are this protective of the ingredients in the fracking fluid.  I simply don't believe that this is a trade secret that is worth keeping simply from a proprietary-protection argument alone.  Surely each of these companies can't have discovered a formula that they think is so wonderful, so much better than their rivals', that they'd engage in all of these dubiously-legal shenanigans to protect it?

Isn't it just slightly more likely that there's something in this fluid that is not exactly "benign?"  Something that might, in fact, be toxic enough that to make it public would alert the public to how much danger they're actually in?

But surely the Toxic Substances Control Act would protect the public from this kind of thing.  That's why it was passed.  Right?

Wrong.  TSCA has an exemption for reporting "Tier 2" exposure to chemicals -- i.e., exposure that happens after the chemicals leave the site of manufacture -- for "petroleum process streams."  If you're exposed to fracking chemicals, you have no federal leverage to force the industry to give you information, much less to force them to stop what they're doing.

So the only way all of this will halt is if enough people know about it, and refuse to sign the fracking leases.  Already we're seeing cases of eminent domain being invoked in laying in pipelines to carry the gas; the only way to halt the industry is to cut off its source.

Which is why it's so critical that people find out about these things.  Because as we've seen, once the damage is done, the industry has been more interested in hushing it up than cleaning it up (or, heaven forfend, changing their ways).  And if that doesn't justify some level of cynicism about their commitment to decency, safety, and public health, I don't know what would.

Microwave phobia

In order to avoid falling for whatever absurd nonsense happen to be in the offing, you not only need to have some good critical thinking skills, you also need a basic knowledge of the sciences.

This is especially critical given the penchant that pseudoscience hacks have for using scientific-sounding terms in bogus ways.  Given that said hacks are quite good at sounding convincing, and can throw around random vocabulary words with the best of 'em, if you don't understand the basic laws of science, as well as a few solid definitions, you're going to fall for whatever tripe they're offering.

Take, for example, the article from Prevent Disease that I've now seen several times on social media, called "12 Facts About Microwaves That Should Forever Terminate Their Use."

[image courtesy of photographer Christian Rasmussen at apoltix.dk, and the Wikimedia Commons]

This piece, written by one Marco Torres, is so full of false statements and specious science that it's hard to know where to start.  Here's a sample, picked more or less at random:
Microwaves are a source of electromagnetic energy (a form of nonionizing form of radiation) electronically generated. When penetrating the aliments, they trigger an inner rotation of the water molecules inside the food. This rotation triggers a friction between the molecules and the result is a rapid growth in temperature.
Okay, he starts out well.  Microwaves are a form of non-ionizing electromagnetic radiation that is electronically generated.  But so is the light from a light bulb.  And I don't know what an "inner rotation of the water molecules" even means -- since microwaves are good at making water molecules (and also fat molecules) spin, maybe this was just a slip.  But the water molecules are not experiencing "friction" -- they're simply moving.  Because that's what an increase in temperature means.  The faster molecules move, the higher the temperature, whether that temperature increase is caused by a microwave, a conventional oven, or just sitting out in the sun.

Then, though, we start hearing about all the bad things this can cause:
Microwaves use super-fast particles to literally radiate the contents of water inside food and bring it to boil. Not only has microwave use been linked to causing infertility in men, but it also denatures many of the essential proteins in the food making them virtually indigestible.
"Super-fast" -- sure, given that all electromagnetic waves travel at the speed of light.  And what's the alternative to "literally radiating" the food?  Figuratively radiating it?

And there is no connection between using microwaves and infertility, as long as you keep your genitalia outside of the microwave oven.  So guys -- if you're microwaving your lunch while naked, don't accidentally shut your junk in the door and then turn the oven on.

Then we have this unintentionally funny statement:
Most animals will only consume food in its natural, unprocessed state, but humans actually go out of their way to render food nutritionally worthless before eating it.
True, I suppose.  I've hardly ever seen a squirrel operating a microwave oven.
Think about all the prepackaged and processed foods we purchase and consume annually. It's no wonder the state of our health is in dire straits.
So here we have a mix of truth, opinion, and blatant falsehood, all in one sentence.  Prepackaged food is wasteful of resources -- consider the practice, common in grocery stores, of individually shrink-wrapping zucchini and cucumbers.  Processed food is another matter -- a lot of canned food (especially things like soups) are sky-high in salt and sugar, and rather low in solid nutritional content.  But as far as "our health (being) in dire straits," it actually isn't.  Our life expectancy and general health is better now than at any time in the Earth's history.  The distant past wasn't some kind of idyll in which our ancestors lived in a healthy, natural paradise; it was closer to the line from Thomas Hobbes' Leviathan.

Solitary, nasty, poor, brutish, and short.

Then we have this:
Microwave ovens work physically, biochemically and physiologically, producing ions and various free radicals, which destroy viruses and bacteria, but not toxins and microtoxins. The experts have concluded that food cooked in microwaves loses between 60% and 90% of its vital energy and, at the same time, the structural disintegration processes accelerates. Also, the nutrient substances are altered, leading to digestive diseases. These microwaves can increase both the number of cancerous cells in blood and the number of stomach and intestinal cancerous cells.
How does non-ionizing radiation produce ions, pray tell?  And it's true that microwaving food won't destroy most toxins, but neither will conventional cooking.  Are you therefore somehow implying that raw toxins are better than cooked ones?  Generally, if your food is toxic, you shouldn't eat it.

And there's no such thing as "vital energy."  Your food is supposed to be dead when you consume it.  My general opinion is that if you're getting your "vital energy" by biting chunks out of live animals, you need psychiatric evaluation, not nutritional counseling.

And there's no connection between microwaves and cancer.  Cf. the Skepticink article I linked above, which explains why that claim is bogus quite nicely.

And so on and so forth.  It's easy to see how someone who isn't well-versed in science might be swayed by this garbage.  Between the science-y sounding language, and the fear talk, you can understand how someone could be alarmed into getting rid of their microwave oven.  The only insurance against this kind of spurious pseudo-journalism is knowing some science, and catching these folks at their game.

So, in short: go ahead and use your microwave.  It's clean, efficient, and has low energy consumption rates.  Used properly, it has no negative health impact.

As long as you don't accidentally microwave your testicles.  I have to admit, that was good advice.
