Lying to our faces

Why are humans so prone to falling for complete bunk?

I ask this question because of two rather distressing studies that I ran into a while back, but which (understandably, when you see what they're about) didn't get much press.  Both of them should make all of us sit up and take notice.

In the first, a group of medical researchers led by Christina Korownyk of the University of Alberta studied over 400 recommendations (each) made on The Dr. Oz Show and The Doctors, medical talk shows in which advice is liberally dispensed to listeners on various health issues.  The recommendations came from forty episodes from each show, and both the episodes and the recommendations were chosen at random.

The recommendations were then evaluated by a team of medical scientists, who looked at the quality of actual research evidence that supported each. It was found that under half of Dr. Oz's claims had evidential support -- and 15% were contradicted outright by the research.  The Doctors did a little better, but still only had a 63% support from the available evidence.

In the second study, an independent non-partisan group called PunditFact evaluated statements on Fox News, MSNBC, and CNN for veracity, placing them in the categories of "True," "Mostly True," "Half True," "Mostly False," "False," and "Pants On Fire."  The latter category was reserved for statements that were so completely out of skew with the facts that they would have put Pinocchio to shame.

Fox News scored the worst, with only 18% of statements in the "True" or "Mostly True" categories.   60% of the statements on Fox were in the lowest three categories.  But before my readers who are on the liberal side of things start crowing with delight, allow me to point out that MSNBC doesn't win any awards for truth-telling, either.  They scored only 31% in the top two categories, and 48% in the lowest three.

Even CNN, which had the best scores, still only had 60% of their statements in the "True" or "Mostly True" categories!


Pretty discouraging stuff. Because far too many people take as gospel the statements heard on these sad examples of media, unquestioningly accepting what they hear as fact.

I think the reason is that so many of us are uncomfortable questioning our baseline assumptions.  If we already believe that liberals are going to lead the United States into ruination, then (1) we'll naturally gravitate toward Fox News, and (2) we'll hear lots of what we already thought was true, and have the lovely experience of feeling like we're right about everything.  Likewise the liberals who think that the Republicans are evil incarnate, and who therefore land right in happy MSNBC fantasy land.

And as the first study shows, this isn't confined to politics.  When Dr. Oz says, "Carb-load your plate at breakfast because it's heart-healthy" (a claim roundly contradicted by the evidence), the listeners who love waffles with lots of maple syrup are likely to say, "Hell yeah!"

What's worse is that when we're shown statements contradictory to our preconceived beliefs, we're likely not even to remember them.  About ten years ago, two of my students did a project in my class where they had subjects self-identify as liberal, conservative, or moderate, and then presented them with an article they'd written containing statistics on the petroleum industry.  The article was carefully written so that half of the data supported a conservative viewpoint (things like "government subsidies for oil companies keep gasoline prices low, encouraging business") and half supported more liberal stances (such as "the increasing reliance on fossil fuels has been shown to be linked with climate change").  After reading the article, each test subject was given a test to see which facts they remembered from it.

Conservatives were more likely to remember the conservative claims, liberals the liberal claims.  It's almost as if we don't just disagree with the opposite viewpoint; on some level we can't even quite bring ourselves to believe it exists.

It's a troubling finding.  This blind spot seems to be firmly wired into our brain, again bringing up the reluctance that all of us have in considering that we might be wrong about something.

The only way out, of course, is through training our brains to suspend judgment until we've found out the facts.  The rush to come to a conclusion -- especially when the conclusion is in line with what we already believed -- is a dangerous path.  All the more highlighting that we need to be teaching critical thinking and smart media literacy in public schools.

And we need to turn off the mainstream media.  It's not that one side or the other is skewed; it's all bad.

Monday's post, about the institutionalized sexism in scientific research, prompted me to decide that this week's Skeptophilia book recommendation is Evelyn Fox Keller's brilliant biography of Nobel Prize-winning geneticist Barbara McClintock, A Feeling for the Organism.

McClintock worked for years to prove her claim that bits of genetic material that she called transposons or transposable elements could move around in the genome, with the result of switching on or switching off genes.  Her research was largely ignored, mostly because of the attitudes toward female scientists back in the 1940s and 1950s, the decades during which she discovered transposition.  Her male colleagues laughingly labeled her claim "jumping genes" and forthwith forgot all about it.

Undeterred, McClintock kept at it, finally amassing such a mountain of evidence that she couldn't be ignored.  Other scientists, some willingly and some begrudgingly, replicated her experiments, and support finally fell in line behind her.  She was awarded the 1983 Nobel Prize in Physiology and Medicine -- and remains to this day the only woman who has received an unshared Nobel in that category.

Her biography is simultaneously infuriating and uplifting, but in the end, the uplift wins -- her work demonstrates the power of perseverance and the delightful outcome of the protagonist winning in the end.  Keller's look at McClintock's life and personal struggles, and ultimate triumph, is a must-read for anyone interested in science -- or the role that sexism has played in scientific research.

Reality blindness

I read an article on CNN yesterday that really pissed me off, something that seems to be happening more and more lately.

The article, entitled "Denying Climate Change As the Seas Around Them Rise" (by Ed Lavandera and Jason Morris), describes the effects of climate change in my home state of Louisiana, which include the loss of entire communities to rising seas and coastline erosion.  An example is the village of Isle Jean Charles, mostly inhabited by members of the Biloxi-Chetimacha tribe, which basically has ceased to exist in the last ten years.

But there are people who will deny what is right in front of their faces, and they include one Leo Dotson of Cameron Parish.  Dotson, a fisherman and owner of a seafood company, "turned red in the face" when the reporters from CNN asked him about climate change.  Dotson said:
I work outside in the weather on a boat, and it's all pretty much been the same for me.  The climate is exactly the same as when I was a kid.  Summers hot, winters cold...  [Climate change] doesn't concern me...  What is science?  Science is an educated guess.  What if they guess wrong?  There's just as much chance for them to be wrong as there is for them to be right.  If [a scientist] was 500 years old, and he told me it's changed, I would probably believe him.  But in my lifetime, I didn't see any change.
Well, you know what, Mr. Dotson?  I'm kind of red in the face right now, myself.  Because your statements go way past ignorance.  Ignorance can be forgiven, and it can be cured.  What you've said falls into the category of what my dad -- also a fisherman, and also a native and life-long resident of Louisiana -- called "just plain stupid."

Science is not an educated guess, and there is not  "just as much chance for them to be wrong as there is for them to be right."  Climate scientists are not "guessing" on climate change.  Because of the controversy, the claim has been tested every which way from Sunday, and every scrap of evidence we have -- sea level rise, Arctic and Antarctic ice melt, earlier migration times for birds, earlier flowering times for plants, more extreme weather events including droughts, heat waves, and storms -- support the conclusion that the climate is shifting dramatically, and that we've only seen the beginning.


At this point, the more educated science deniers usually bring up the fact that there have been times that the scientific establishment has gotten it wrong, only to be proven so, sometimes years later.  Here are a few examples:
  1. Darwin's theory of evolution, which overturned our understanding of how species change over time.
  2. Mendel's experiments in genetics, later bolstered by the discovery of the role of DNA and chromosomes in heredity.  Prior to Mendel's time, our understanding of heredity was goofy at best (consider the idea, still prevalent in fairy tales, of "royal blood" and the capacity for ruling being inheritable, which you'd think that any number of monarchs who were stupid, incompetent, insane, or all three would have been sufficient to put to rest).
  3. Alfred Wegener's postulation of "continental drift" in 1912, which was originally ridiculed so much that poor Wegener was forced to retreated in disarray.  The fact that he was right wasn't demonstrated for another forty years, through the work of such luminaries in geology as Harry Hess, Tuzo Wilson, Fred Vine, Drummond Matthews, and others.
  4. The "germ theory of disease," proposed by Marcus von Plenciz in 1762, and which wasn't widely accepted until the work of Robert Koch and Louis Pasteur in the 1870s.
  5. Big Bang cosmology, discovered from the work of astronomers Georges LemaƮtre and Edwin Hubble.
  6. Albert Einstein's discovery of relativity, and everything that came from it -- the speed of light as an ultimate universal speed limit, time dilation, and the theory of simultaneity.
  7. The structure of the atom, a more-or-less correct model of which was first described by Niels Bohr, and later refined considerably by the development of quantum mechanics.
There.  Have I forgotten any major ones?  My point is that yes, prior to each of these, people (including scientists) believed some silly and/or wrong ideas about how the world works, and that there was considerable resistance in the scientific community to accepting what we now consider theory so solidly supported that it might as well be considered as fact.  But you know why these stand out?

Because they're so infrequent.  If you count the start of the scientific view of the world as being some time during the Enlightenment -- say, 1750 or so -- that's 267 years in which there have been only seven times there has been a major model of the universe overturned and replaced by a new paradigm.  Mostly what science has done is to amass evidence supporting the theories we have -- genetics supporting evolution, the elucidation of DNA's structure by Franklin, Crick, and Watson supporting Mendel, the discovery of the 3K cosmic microwave background radiation by Amo Penzias and Robert Wilson supporting the Big Bang.

So don't blather at me about how "science gets it wrong as often as it gets it right."  That's bullshit.  If you honestly believe that, you better give up modern medicine and diagnostics, airplanes, the internal combustion engine, microwaves, the electricity production system, and the industrial processes that create damn near every product we use.

But you know what?  I don't think Dotson and other climate change deniers actually do believe that.  I doubt seriously whether Dotson would go in to his doctor for an x-ray, and when he gets the results say, "Oh, well.  It's equally likely that I have a broken arm or not, so what the hell?  Might as well not get a cast."  He doesn't honestly think that when he pulls the cord to start his boat motor, it's equally likely to start, not start, or explode.

No, he doesn't believe in climate change because it would require him to do something he doesn't want to do.  Maybe move.  Maybe change his job.  Maybe vote for someone other than the clods who currently are in charge of damn near every branch of government.  So because the result is unpleasant, it's easier for him to say, "ain't happening," and turn red in the face.

But the universe is under no obligation to conform to our desires.  Hell, if it was, I'd have a magic wand and a hoverboard.  It's just that I'm smart enough and mature enough to accept what's happening even if I don't like it, and people like Dotson -- and Lamar Smith, and Dana Rohrabacher, and James "Snowball" Inhofe, and Scott Pruitt, and Donald Trump -- apparently are not.

The problem is, there's not much we can do to fix this other than wait till Leo Dotson's house floats away.  Once people like him have convinced themselves of something, there's no changing it.

I just have to hope that our government officials aren't quite so intransigent.  It'd be nice to see them wake up to reality before the damage done to our planet is irrevocable.

Sifting fact from fiction

President-elect Donald Trump's latest ploy, any time he is criticized in the press, is to claim that what they're saying is "fake news."  (That, and to threaten to revoke their right to cover his speeches.)

Five days ago, he tweeted (of course, because that's how adults respond to criticism) that the Russian dossier alleged to have compromising information on him was "fake news and crap."  The, um, interaction he is alleged to have had with some Russian prostitutes was likewise "fake news, phony stuff, it did not happen."  About CNN, he said the "organization’s terrible...  You are fake news."  He's banned reporters from The Washington Post from attending his events, calling it "incredibly inaccurate... phony and dishonest."

There are two things that are troubling about this.

One is that Trump himself has been responsible for more than one demonstrably false claim intended to do nothing but damage his opponents.  Kali Holloway of AlterNet found fourteen, in fact.  Trump either created himself, or was responsible for publicizing, claims such as the following:
  • Barack Obama was a Kenyan Muslim and never attended Columbia University
  • Hillary Clinton was covering up a chronic debilitating illness and was too sick to serve
  • Ted Cruz's father was involved in the plot to kill John F. Kennedy
  • Thousands of Muslims in and around New York City had a public demonstration to cheer the events of 9/11
  • Supreme Court Justice Antonin Scalia was murdered
  • 97% of the murders in the United States are blacks killing other blacks (when confronted on this blatantly false claim, he said, "It was just a retweet... am I going to check every statistic?")
  • Millions of votes in the presidential election were cast illegally
  • Climate change is a Chinese hoax
  • Vaccines cause autism -- and that the doctors opposing this fiction deliberately lied to cover it up
And so on and so forth.

So Trump calling out others for fake news should definitely be an odds-on contender for the "Unintentional Irony of the Year" award for 2017.

The more upsetting aspect of this, however, is that Trump is implying that you can't trust anything on the media -- except, of course, what comes out of his mouth.  The implication is that nothing you see on the news or read in the newspaper is true, that the default stance is to say it's all fake.

This is a profoundly disturbing claim.  For one thing, as I've said many times before, cynicism is no more noble (or correct) than gullibility; disbelieving everything is exactly as lazy and foolish as believing everything.  For another, the media are really our only way of finding out what is happening in the world.  Without media, we would not only have no idea what was going on in other countries, our own government would be operating behind a smokescreen, their machinations invisible to everyone but those in on the game.

Which is a fine way to turn a democracy into a dictatorship.

There is some small kernel of truth to the accusation, however; it is true that all media are biased.  That CNN and MSNBC slant to the left and Fox and The Wall Street Journal slant to the right is so obvious that it hardly bears mention.  To jump from there to "everything they say is a lie," however, is to embrace a convenient falsehood that allows you to reject everything you hear and read except for what fits with your preconceived notions -- effectively setting up your own personal confirmation bias as the sine qua non of understanding.

The truth, of course, is more nuanced than that, and also far more powerful.  We are all capable of sifting fact from fiction, neither believing everything nor rejecting everything.  It's called critical thinking, and in these rather fractious times it's absolutely... well, critical.  As biologist Terry McGlynn put it, "When we teach our students to distinguish science from pseudoscience, we are giving them the skills to identify real and fake journalism."

I won't lie to you.  Sorting fact from fiction in the media (or anywhere else) is hard work, far harder than simply accepting what we'd like to believe and rejecting what we'd like to be false.  But it's possible, and more than that, it's essential.  Check sources -- even if (especially if) they're from your favorite media source.  Check them using sources that have a different slant.  Go to the original documents instead of merely reading what someone else has written about them.  Apply good rules of thumb like Ockham's Razor and the ECREE (Extraordinary Claims Require Extraordinary Evidence) principle.  Pay special attention to claims from people who have proven track records of lying, or people who are making claims outside of their area of expertise.

Donald Trump's snarling of "fake news, phony journalism" every time he's criticized should immediately put you on notice that what he's saying is questionable -- not (again) that it should be disbelieved out of hand, but that it should be scrutinized.  Over the next four years, people on both sides of the aisle are going to have to be on guard -- never in my memory has the country been so polarized, so ready to begin that precipitous slide into sectarian violence that once begun is damn near impossible to halt.  Our leaders are showing no inclination to address the problems we face honestly and openly -- so it falls to us as responsible citizens to start sifting through their claims more carefully instead of simply accepting whatever half-truths or outright lies fit our preconceived notions.

Political astrology

There is one word that makes me see red, skepticism-wise, and that word is "clickbait."

Clickbait articles, sensationalized bullshit that has as its only point inducing gullible people to click on links and therefore generate advertising revenue, are bad enough from an ethical standpoint.  But what really torques me about this sort of thing is the fact that many of the clickers end up believing what they read, regardless of the reliability of the source.  The strategy started with such dubious sites as The Weekly World News and Above Top Secret, but has moved its way into more mainstream media (The Daily Mail has adopted this approach to the extent that most of us refer to it as The Daily Fail).  And now, it has moved all the way up to the media source on which I found a clickbait article yesterday...

... none other than CNN.

The article in question, which required the collaboration of no less than three authors -- Pamela Boykoff, Alexandra Field, and Jason Kwok -- is entitled, "2016 Election: Which Candidate Will Triumph in the Year of the Monkey?"  And it is about -- yes -- using feng shui and Chinese astrology to predict who's going to win in November.

The worst part about this is that it's not even in some kind of "Weird Stuff" category of CNN's webpage.  It's filed squarely under CNN Politics.  Let me be clear about this: this is not politics.  This is pseudoscientific nonsense.  Let me give you a taste of what's on it, so you don't have to click on the link and give them ad money yourself:
With the Year of the Monkey and the New Hampshire primary upon us, CNN asked Hong Kong fortune teller Priscilla Lam to divine the fates of the candidates battling it out for the U.S. presidency. 
A practitioner of feng shui, the ancient Chinese system of summoning good luck, she combined the art of face reading with analysis of the candidates' birthdays and current life cycles according to the Chinese Zodiac. 
She says the new lunar year will fuel good fortune for "earth dog" Donald Trump, while also lighting a fire under Hillary Clinton. 
Bernie Sanders' missing metal is a problem with older voters and the fighting elements of fire, and water might just leave Marco Rubio all wet.  And don't ask about Ted Cruz's face reading. 
Lam says she is "about 80%" confident in her predictions for the 2016 election. Those sound like pretty good odds.
So, yeah.  That's the level of political reporting we're seeing.  Trump's going to do well because he's an "earth dog."  Hillary Clinton's on fire.

And trust me, I don't even want to think about Ted Cruz's face, much less read it.

If we further peruse the article, we find out that Donald Trump has "a lot of sunshine in his favor."  that Hillary Clinton "has flexible lips," that Marco Rubio's "nose is okay -- it means management skill or power," and that Ted Cruz is in trouble because "in his birthday there is no wood... if you burn the wood, the fire can come up."

Whatever the fuck that means.

And the whole time I'm looking at this, I'm thinking, "how the hell is this news?"

The answer, of course, is that it isn't.  This is clickbait.  But the problem is, seeing such nonsense on a an internationally-known news media source gives it a veneer of authority, and reinforces the belief people have in such pseudoscientific claptrap.

So I'm really not able to laugh this sort of thing off.  I spend enough time, as a high school science teacher, trying to instill in students a good understanding of how the universe works, along with some skills regarding telling truth from falsehood.  Having something like this in mainstream media just makes my job that much harder, something I very much don't need.  Fighting the creationists and the climate-change deniers is bad enough; I really don't want to have to do battle with the Chinese astrologers as well.
