I’m sitting on a train when a group of football fans streams on.
Fresh from the game – their team has clearly won – they occupy
the empty seats around me. One picks up a discarded newspaper and
chuckles derisively as she reads about the latest “alternative
facts” peddled by Donald Trump.

The others soon chip in with their thoughts on the US president’s
fondness for conspiracy theories. The chatter quickly turns to
other conspiracies and I enjoy eavesdropping while the group
brutally mock flat Earthers, chemtrails memes and Gwyneth Paltrow’s latest idea.

Then there’s a lull in the conversation, and someone takes it as
an opportunity to pipe in with: “That stuff might be nonsense,
but don’t try and tell me you can trust everything the mainstream
feeds us! Take the moon landings, they were obviously faked and
not even very well. I read this blog the other day that pointed
out there aren’t even stars in any of the pictures!”

To my amazement the group joins in with other “evidence”
supporting the moon landing hoax: inconsistent shadows in
photographs, a fluttering flag when there’s no atmosphere on the
moon, how Neil Armstrong was filmed walking on to the surface
when no-one was there to hold the camera.

A minute ago they seemed like rational people capable of
assessing evidence and coming to a logical conclusion. But now
things are taking a turn down crackpot alley. So I take a deep
breath and decide to chip in.

“Actually all that can be explained quite easily … ”

They turn to me aghast that a stranger would dare to butt into
their conversation. I continue undeterred, hitting them with a
barrage of facts and rational explanations.

“The flag didn’t flutter in the wind, it just moved as Buzz
Aldrin planted it! Photos were taken during lunar daytime – and
obviously you can’t see the stars during the day. The weird
shadows are because of the very wide-angle lenses they used which
distort the photos. And nobody took the footage of Neil
descending the ladder. There was a camera mounted on the outside
of the lunar module which filmed him making his giant leap. If
that isn’t enough then the final clinching proof comes from the
Lunar Reconnaissance Orbiter’s photos of the
landing sites where you can clearly see the tracks that the
astronauts made as they wandered around the surface.

“Nailed it!” I think to myself.

But it appears my listeners are far from convinced. They turn on
me, producing more and more ridiculous claims. Stanley Kubrick
filmed the lot, key personnel have died in mysterious ways, and
so on …

The train pulls up in a station, it isn’t my stop but I take the
opportunity to make an exit anyway. As I sheepishly mind the gap
I wonder why my facts failed so badly to change their minds.

The simple answer is that facts and rational arguments really
aren’t very good at altering people’s beliefs. That’s because our
rational brains are fitted with not-so-evolved evolutionary hard
wiring. One of the reasons why conspiracy theories spring up with
such regularity is due to our desire to impose structure on the
world and incredible ability to recognise patterns. Indeed, a
recent study showed a correlation between an individual’s need
for structure and tendency to believe in a conspiracy theory.

Take this sequence for example:

0 0 1 1 0 0 1 0 0 1 0 0 1 1

Can you see a pattern? Quite possibly – and you aren’t alone. A
quick twitter poll (replicating a much more rigourous study) suggested that
56% of people agree with you – even though the sequence was
generated by me flipping a coin.

 It seems our need for structure and our pattern
recognition skill can be rather overactive, causing a tendency to
spot patterns – like constellations,
clouds that looks like dogs and vaccines
causing autism – where in fact there are none.

The ability to see patterns was probably a useful survival trait
for our ancestors – better to mistakenly spot signs of a predator
than to overlook a real big hungry cat. But plonk the same
tendency in our information rich world and we see nonexistent
links between cause and effect – conspiracy theories – all over
the place.

Peer pressure

Another reason we are so keen to believe in conspiracy theories
is that we are social animals and our status in that society is
much more important (from an evolutionary standpoint) than being
right. Consequently we constantly compare our actions and beliefs
to those of our peers, and then alter them to fit in. This means
that if our social group believes something, we are more likely
to follow the herd.

This effect of social influence on behaviour was nicely
demonstrated back in 1961 by the street corner experiment, conducted by the US
social psychologist Stanley Milgram (better known for his work on
obedience to authority figures) and colleagues.
The experiment was simple (and fun) enough for you to replicate.
Just pick a busy street corner and stare at the sky for 60
seconds.

Most likely very few folks will stop and check what you are
looking at – in this situation Milgram found that about 4% of the
passersby joined in. Now get some friends to join you with your
lofty observations. As the group grows, more and more strangers
will stop and stare aloft. By the time the group has grown to 15
sky gazers, about 40% of the by-passers will have stopped and
craned their necks along with you. You have almost certainly seen
the same effect in action at markets where you find yourself
drawn to the stand with the crowd around it.

The principle applies just as powerfully to ideas. If more people believe a piece of information,
then we are more likely to accept it as true. And so if, via our
social group, we are overly exposed to a particular idea then it
becomes embedded in our world view. In short social proof is a much more effective persuasion
technique than purely evidence-based proof, which is of course
why this sort of proof is so popular in advertising (“80% of mums
agree”).

Social proof is just one of a host of logical fallacies that also cause us to
overlook evidence. A related issue is the ever-present confirmation bias, that tendency for folks to
seek out and believe the data that supports their views while
discounting the stuff that doesn’t. We all suffer from this. Just
think back to the last time you heard a debate on the radio or
television. How convincing did you find the argument that ran
counter to your view compared to the one that agreed with it?

The chances are that, whatever the rationality of either side,
you largely dismissed the opposition arguments while applauding
those who agreed with you. Confirmation bias also manifests as a
tendency to select information from sources that already agree
with our views (which probably comes from the social group that
we relate too). Hence your political beliefs probably dictate
your preferred news outlets.

The
difference.


The
Conversation



Of course there is a belief system that recognises logical
fallacies such as confirmation bias and tries to iron them out.
Science, through repetition of observations, turns anecdote into
data, reduces confirmation bias and accepts that theories can be
updated in the face of evidence. That means that it is open to
correcting its core texts. Nevertheless, confirmation bias
plagues us all. Star physicist Richard Feynman famously described an example of
it that cropped up in one of the most rigorous areas of sciences,
particle physics.

“Millikan measured the charge on an electron by an experiment
with falling oil drops and got an answer which we now know not
to be quite right. It’s a little bit off, because he had the
incorrect value for the viscosity of air. It’s interesting to
look at the history of measurements of the charge of the
electron, after Millikan. If you plot them as a function of
time, you find that one is a little bigger than Millikan’s, and
the next one’s a little bit bigger than that, and the next
one’s a little bit bigger than that, until finally they settle
down to a number which is higher.”

“Why didn’t they discover that the new number was higher right
away? It’s a thing that scientists are ashamed of – this
history – because it’s apparent that people did things like
this: When they got a number that was too high above
Millikan’s, they thought something must be wrong and they would
look for and find a reason why something might be wrong. When
they got a number closer to Millikan’s value they didn’t look
so hard.”

Myth-busting mishaps

You might be tempted to take a lead from popular media by
tackling misconceptions and conspiracy theories via the
myth-busting approach. Naming the myth alongside the reality
seems like a good way to compare the fact and falsehoods side by
side so that the truth will emerge. But once again this turns out
to be a bad approach, it appears to elicit something that has
come to be known as the backfire effect, whereby the myth ends up
becoming more memorable than the fact.

One of the most striking examples of this was seen in a study
evaluating a “Myths and Facts” flyer about flu vaccines.
Immediately after reading the flyer, participants accurately
remembered the facts as facts and the myths as myths. But just 30
minutes later this had been completely turned on its head, with
the myths being much more likely to be remembered as “facts”.

The thinking is that merely mentioning the myths actually helps
to reinforce them. And then as time passes you forget the context
in which you heard the myth – in this case during a debunking –
and are left with just the memory of the myth itself.

To make matters worse, presenting corrective information to a
group with firmly held beliefs can actually strengthen their view, despite the new
information undermining it. New evidence creates inconsistencies
in our beliefs and an associated emotional discomfort. But
instead of modifying our belief we tend to invoke
self-justification and even stronger dislike of opposing
theories, which can make us more entrenched in our views. This has become known
as the as the “boomerang effect” – and it is a huge problem when
trying to nudge people towards better behaviours.

For example, studies have shown that public information messages
aimed at reducing smoking, alcohol and drug consumption all had the reverse effect.

So if you can’t rely on the facts how do you get people to bin
their conspiracy theories or other irrational ideas?

Scientific literacy will probably help in the long run. By this I
don’t mean a familiarity with scientific facts, figures and
techniques. Instead what is needed is literacy in the scientific
method, such as analytical thinking. And indeed studies show that dismissing conspiracy
theories is associated with more analytic thinking. Most people
will never do science, but we do come across it and use it on a
daily basis and so citizens need the skills to critically assess
scientific claims.

Of course, altering a nation’s curriculum isn’t going to help
with my argument on the train. For a more immediate approach,
it’s important to realise that being part of a tribe helps
enormously. Before starting to preach the message, find some
common ground.

Meanwhile, to avoid the backfire effect, ignore the myths. Don’t
even mention or acknowledge them. Just make the key points:
vaccines are safe and reduce the chances of getting flu by between 50% and
60%
, full stop. Don’t mention the misconceptions, as they
tend to be better remembered.

Also, don’t get the opponents gander up by challenging their
worldview. Instead offer explanations that chime with their
preexisting beliefs. For example, conservative climate-change
deniers are much more likely to shift their views if they are
also presented with the pro-environment business opportunities.

One more suggestion. Use stories to make your point. People
engage with narratives much more strongly than with
argumentative or descriptive dialogues. Stories link cause and
effect making the conclusions that you want to present seem
almost inevitable.

All of this is not to say that the facts and a scientific
consensus aren’t important. They are critically so. But an an
awareness of the flaws in our thinking allows you to present your
point in a far more convincing fashion.

It is vital that we challenge dogma, but instead of linking
unconnected dots and coming up with a conspiracy theory we need
to demand the evidence from decision makers. Ask for the data
that might support a belief and hunt for the information that
tests it. Part of that process means recognising our own biased
instincts, limitations and logical fallacies.

So how might my conversation on the train have gone if I’d heeded
my own advice… Let’s go back to that moment when I observed that
things were taking a turn down crackpot alley. This time, I take
a deep breath and chip in with.

“Hey, great result at the game. Pity I couldn’t get a ticket.”

Soon we’re deep in conversation as we discuss the team’s chances
this season. After a few minutes’ chatter I turn to the lunar
landing conspiracy theorist “Hey, I was just thinking about that
thing you said about the moon landings. Wasn’t the sun visible in
some of the photos?”

He nods.

“Which means it was daytime on the moon, so just like here on
Earth would you expect to see any stars?”

“Huh, I guess so, hadn’t thought of that. Maybe that blog didn’t
have it all right.”
