think about all that goes on. If we scale up the population to
730 million, we come to Europe at about the right size. Now
take Europe and shrink it until it all fits in the same land mass
as Ithaca.

Number Smiths
Every industry has numbers, and nearly every presenter in every
industry fails to make numbers interesting and meaningful. For
the rest of this scene, let’s examine several examples of individ-
uals and companies who have accomplished what Jobs does in
every presentation—make numbers meaningful.
DEFINING ONE THOUSAND TRILLION
On June 9, 2008, IBM issued a press release touting a superfast
supercomputer. As its name suggests, Roadrunner is one really
quick system. It operates at one petaflop per second. What’s a
petaflop? Glad you asked. It’s one thousand trillion calculations
per second. IBM realized that the number would be meaning-
less to the vast majority of readers, so it added the following description:
How fast is a petaflop? Lots of laptops. That’s roughly equiva-
lent to the combined computing power of 100,000 of today’s
fastest laptop computers. You would need a stack of laptops
1.5 miles high to equal Roadrunner’s performance.

DELIVER THE EXPERIENCE
It would take the entire population of the earth
—
about
six billion—each of us working a handheld calculator at the
rate of one second per calculation, more than 46 years to do
what Roadrunner can do in one day.
If it were possible for cars to improve their gas mileage
over the past decade at the same rate that supercomputers
have improved their cost and efficiency, we’d be getting
200,000 miles to the gallon today
.6
The comparisons were compelling and caught the attention of
the media. Conduct a Google search for “IBM + Roadrunner +
1.5 miles” and the search returns nearly twenty thousand links
to articles that use IBM’s comparison word for word from the
press release. The analogy works.
$700 BILLION BAILOUT
The bigger the number, the more important it is to place the
number into a context that makes sense to your audience. For
example, in October 2008, the U.S. government bailed out banks
and financial institutions to the tune of $700 billion. That’s the
numeral 7 followed by eleven zeros, a number so large that few
of us can get our minds around it.
San Jose Mercury News
reporter Scott Harris put the number into a context his Silicon Valley
readers could understand: $700 billion is twenty-five times the
combined wealth of the Google guys. It is the equivalent of 350
billion venti lattes at Starbucks or 3.5 billion iPhones. The gov-
ernment could write checks for $2,300 to every man, woman,
and child in America or provide free education for twenty-three
million college students. Few people can grasp the concept of
700 billion, but they know lattes and college tuitions. Those
numbers are specific and relevant
.7
CHIPPING DOWN $13 TRILLION
Environmental groups go to great lengths to make numbers
more meaningful. They must if they hope to persuade individ-
uals to break deeply ingrained habits and routines that might
contribute to damaging climate change. The numbers are sim-
ply too big (and seemingly irrelevant) without connecting the
DRESS UP YOUR NUMBERS

dots. For example, try telling someone that in 2006 alone, the
United States produced thirteen trillion pounds of carbon diox-
ide (CO ). It sounds like a humongous number, but what does
2
it mean? There is no context. Thirteen trillion could be small
or large in comparison with other countries. And frankly, what
would it mean to the average person? The number itself won’t
persuade people to change their habits.
Al Gore’s website, ClimateCrisis.org, breaks the number down
further, claiming the average American is responsible for 44,000
pounds of CO emissions per year, while the world average is
2
9,600 pounds per individual
.8
That’s specific and contextual.
The site then makes the number even more relevant by tell-
ing its readers what might happen if that number doesn’t come
down: heat waves will be more frequent and intense, droughts
and wildfires will occur more often, and more than a million
species could be driven to extinction in the next fifty years.
Scientists at NOAA (National Oceanic and Atmospheric
Administration) are also catching on. Senior scientist Susan
Solomon once told the
New York Times
that if the burning of fos-sil fuels continues at its present rate, carbon dioxide emissions
could reach 450 parts per million. What does that figure mean?
According to Solomon, at 450 parts per million, rising seas will
threaten coastal areas around the world, and western Australia
could expect 10 percent less rainfall. “Ten percent may not seem
like a high number,” said Solomon, “but it is the kind of number
that has been seen in major droughts in the past, like the Dust
Bowl.
”9
Whether or not you believe in global warming, climate
change experts such as Al Gore and Susan Solomon are mas-
ters at making large numbers meaningful, and by doing so,
they hope to persuade governments and individuals to take the
action they deem necessary to solve the problem.
CHANGE YOUR DIET OR PAY THE ULTIMATE PRICE
What if you knew nothing about blood pressure and a doctor
told you your blood pressure was 220 over 140? Would you be
motivated to change your diet and exercise habits? Perhaps not
until those numbers are put into context that makes sense to
112
DELIVER THE EXPERIENCE
you. One doctor I know once told a patient, “Your blood pres-
sure is 220 over 140. We consider 120 over 80 to be normal.
Your blood pressure is severely high. That means you have a
much higher risk of having a heart attack, kidney disease, and
stroke. In fact, with numbers this high, you could drop dead at
any minute by blowing your gourd. The arteries in your brain
will literally burst.” By being specific, relevant, and contextual,
the doctor made his point and motivated his patient to make
changes right away!
Regardless of what industry you’re in, the numbers you throw
around will have little impact on your audience unless and until
you make them meaningful. Numbers out of context are sim-
ply unimpressive. Whether you’re presenting the data behind a
new technology or a particular medical condition, comparing
the number to something your listeners can relate to will make
your message far more interesting, impactful, and ultimately
persuasive.
D IR EC TO R ’ S N OT E S
Use data to support the key theme of your presentation.
As you do, consider carefully the figures you want to
present. Don’t overwhelm your audience with too many
numbers.
Make your data specific, relevant, and contextual. In
other words, put the numbers into a context that is
relevant to the lives of your listeners.
Use rhetorical devices such as analogies to dress up your
numbers.

STEVE JOBS, DESCRIBING THE SONG TRANSFER FEATURE
OF THE FIRST IPOD, FORTUNE, NOVEMBER 2001
Steve Jobs introduced an upgrade to the iPhone at Apple’s
Worldwide Developers Conference on June 9, 2008.
The iPhone 3G was twice as fast as the original model,
supporting the speedier third-generation AT&T data
network. A 3G network has a potential transfer speed of 3 Mbps,
versus 144 Kbps on a slower, 2G (second-generation) network.
Simply put, 3G is better for accessing the Internet and down-
loading large multimedia files on a mobile phone. Jobs made it
even simpler. “It’s amazingly zippy,” he said
.1
Jobs speaks in simple, clear, and direct language, free of the
jargon and complexity so common in business communications.
Jobs is one of the few business leaders who could confidently call
a product “amazingly zippy.” In an interview for
Fortune
maga-
zine, he was asked to describe the interface of Apple’s new OS X
operating system. “We made the buttons on the screen look so
good, you’ll want to lick them,” he said.

Even if you think Jobs is grandstanding from time to time, his choice of words puts a
smile on your face. He chooses words that are fun, tangible, and
uncommon in most professional business presentations.

DELIVER THE EXPERIENCE
Jobs, Gates, and the Plain English Test
Seattle Post Intelligencer
tech reporter Todd Bishop wrote a clever piece at the urging of his readers. He ran the transcripts from
four presentations in 2007 and 2008 (Steve Jobs’s Macworld key-
notes and Bill Gates’s Consumer Electronics Show presentations)
through a software tool that analyzes language. In general,
the lower the numerical score, the more understandable the
language.
Bishop used an online software tool provided by UsingEnglish
.com
.3
The tool analyzes language based on four criteria:
1.
Average number of words per sentence.
2.
Lexical density—how easy or difficult a text is to read. Text with “lower density” is more easily understood. In this case,
a lower percentage is better.
3.
Hard words—average number of words in a sentence that
contain more than three syllables. In this case, a higher
percentage is worse because it implies that are more “hard
words” in the text that are generally less understood by the
average reader.
4.
Fog index—the number of years of education a reader
theoretically would require to understand the text. For
example, the New York Times has a fog rating of 11 or 12,
while some academic documents have a fog rating of 18.
The fog index simply means that short sentences written in
plain English receive a better score than sentences written
in complicated language.
It should be no surprise that Jobs did noticeably better than Gates when their language was put to the test. Table 10.1 compares the results for both 2007 and 2008
.4
In each case, Jobs performs significantly better than Gates
when it comes to using terms and language people can eas-
ily understand. Jobs’s words are simpler, his phrases are less
abstract, and he uses fewer words per sentence.
