NEW SCIENTIST readers are more
knowledgeable than the general
public and experts on certain issues,
but don’t score much better than
monkeys would on some questions.
“To score worse than monkeys
requires misconceptions,” Ola
Rosling, author of Factfulness, told
attendees of New Scientist Live on
10 October. Most people are not
only ignorant of some basic facts
about the world, they don’t even

realise they are ignorant, he said.
For example, about 88 per cent
of children around the world are
now vaccinated against at least one
disease, but most people think the
figure is much lower. When asked if
this proportion is around 20, 50 or
80 per cent, only about 15 per cent
of people in countries such as the US
and the UK get the answer right in
Rosling’s surveys. At a recent world
health summit, only 27 per cent
of attendees got it right. Nobel
laureates and medical scientists
would be outsmarted by monkeys
randomly picking answers, he said.
New Scientist readers do a bit

better, though. In an online survey,
46 per cent of New Scientist
readers correctly answered the
vaccination question. On climate,
they excelled. When asked what
climate experts believe will happen
to global temperatures over the
next 100 years – grow warmer,

cooler or stay the same – 99 per
cent opted for the right answer.
In other surveys, the proportion
answering correctly has ranged
from 94 per cent in Hungary to
just 76 per cent in Japan. In the US,
81 per cent get it right and 87 per
cent do so in the UK.
But on questions about
endangered species and world
population trends, New Scientist
readers fared worse. Overall, they
got 3.9 out of 12 questions right.
“That’s on par with monkeys,”
said Rosling. The average score
is just 2.2.  ❚

AUTOMATED accounts on social
media platforms have been
accused of many abuses, including
large-scale political manipulation,
but they aren’t all bad. Speaking
at New Scientist Live on 12 October,
Tony Veale from University
College Dublin, Ireland, and
Mike Cook from Queen Mary
University of London argued that
bots can also be forces for good.
For example, many Twitter
bots created for fun or art don’t
pretend to be human, unlike
those with more serious or
sinister aims. These bots
often follow in the footsteps
of surrealist artists, working
to make the everyday seem new
and fascinating, said Veale.
“When a bot strives to be
creative, people respond
creatively,” he said. People choose
to follow bots to see how they
subvert our expectations by
building language algorithmically
rather than intuitively, he said.
Cook shared a number of
examples, including a bot that
tweeted every word from the
dictionary in order, provoking
startling engagement with certain

words. Notably, “butt” received far
more retweets than the average.
“Lots of people in our field see
this as the future of creativity,”
said Cook. Anyone with a basic
knowledge of coding can build a
bot, and its success relies on how
others interact with it. “Some of
the best bots are incredibly simple.
It’s really about how it works
in the space that it’s in,” he said.

Cook also demonstrated three
Twitter bots that he had created
for the event. All three use a set
of 45,000 New Scientist headlines
that have appeared online since
2003 to build new headlines, but
each bot uses a different method.
The first bot (@NewerScientist1)
uses a neural network that learns
from the original headlines
to generate strange new
ones, including gems such as
“Self-destruction of the brain
power” and “Inside the most
powerful thing”.

The second (@NewerScientist2)
uses a Markov chain, which works
by learning what words generally
go together in New Scientist
headlines and combining them

in common orders. Its output
includes “Global warming: Will
the anaconda or the ‘Garbage of
Eden’?” and “A total solar eclipse
with non-addictive cigarettes by
alien worlds without words”.
The final bot (@NewerScientist3)
uses a simpler protocol similar to
cut-and-paste methods used in
songwriting by artists like David
Bowie. Cook divided the headlines
into lists of topics; the bot replaces
words from a headline under one
topic with words from another.
Its output included headlines
such as “There may already be
crows on Mars”, “Tiny pebbles may
be the reason most politicians
spin in the same direction” and
“Leopards that live in memes are
protecting people from rabies”. ❚

“ One dictionary-tweeting
bot provoked startling
engagement when it
posted the word ‘butt’”
