Social media is capable of spreading misinformation as
quickly as solid facts. Not only that,
but it spreads this misinformation at greater speeds and breadth than ever
before. It behooves everyone, therefore,
to be extra alert, cautious and skeptical.
Unfortunately, Americans have not learned this lesson. This lack of care and skepticism is shown by
the very fact that misinformation spreads so widely.
A couple of examples came up this month. This first is in a report from NBC that
begins, “Hyperbaric oxygen therapy. Have you ever heard of it? The Internet
sure has.” It goes on to say that the
use of this procedure that exposes patients to 100% oxygen at greater than
atmospheric pressure, at $2000 per treatment, is becoming more common “for treating
autism, infant brain trauma, multiple sclerosis, chronic fatigue, cerebral
palsy and many other conditions,” which lately include PTSD and traumatic brain
injury for veterans. The trouble is that
there is no solid evidence that it works.
They cite a recent JAMA Internal Medicine study on its
effectiveness for treating some veterans with PTSD finding that benefits were
not a result of the therapy but the placebo effect. “Those in the tanks felt better because they
really wanted to believe they would feel better even when they just breathed
room air.” Belief in remedies can be
powerful even when the remedies themselves are no better than sugar pills. Furthermore, self-reporting is also suspect
due to this placebo effect along with many other psychological factors. That is why we shouldn’t, but often do, take
at face value the testimonials of friends, neighbors, social media contacts, or
celebrity spokespersons – or even our own experience.
The second example was news that Pope Francis told a young
boy that his pet went to heaven. Pets
going to heaven was good news, something almost everyone wants to believe. It spread quickly, even on the mainstream
media. Unfortunately, that’s not quite
what he said. The New York Times “acknowledged its mistake, saying in a correction on Friday that it had misattributed the
remark by Paul VI to the current pope.”
Pope Francis did not make any comments about animals. It was all a misinterpretation by an Italian
reporter that spread with elaboration. (Later in the
month a picture of the Pope circulated on Facebook with a quote about not having to believe
in God. According to a quick check of
the Snopes website, “there is no proof for the claim that Pope Francis said it.”)
Whether pets are admitted to heaven or hyperbaric treatment
cures PTSD is not an immediate problem in most cases. These are just current examples, but other misinformation
can seriously affect your wallet and your health. The latest trends catch on based on celebrity
endorsements and Internet chatter with no science required. Think about how foods that would not
naturally contain gluten are now labeled gluten-free based on a fad of
self-diagnosis. Think how many foods
carry the meaningless label of “all natural” just to attract uniformed buyers. These may make a dent in the wallet, but far
more serious is the bad health advice, such as avoiding vaccinations, taking
supplements for serious conditions, turning down proven cures for home remedies
or ancient natural alternatives with no track record except the misperception
that “ancient” or “Chinese” always means good, safe and effective. Companies and individuals can get their
reputations savaged as the unchallenged stories of misdeeds or dangerous
products spreads like wildfire. As I
mentioned last time, a check of original sources is often all it takes to find
that a posting about dangers or magical cures is based on incomplete
evidence. Taking the better-safe-than-sorry
approach on everything leaves us unwilling to even cross the street.
There have always been dangers associated with not being
skeptical, being too credulous or accepting.
Years ago the locals would give money to the traveling medicine man only
to find out too late that they had been cheated. Today we encounter the same interaction many
times a day on the Internet, social media, magazines, and the news. Critical thinking, a skeptical attitude, is
more important than ever to protect ourselves against not only cheats and conmen,
but also against sneaky advertisers and our naïve neighbors who “like” and
repost unproven and unprovable “facts” without doing any investigation.
Update
December 21: Two days after publication,
I became aware of a move by the American Dental Association (ADA) to spend $500,000
to counter the increase of inaccurate
information on the Internet posted by groups that try to influence
communities to ban drinking water fluoridation.
