How not to be ignorant about the world | Hans and Ola Rosling
Summary
TLDRHans Rosling stellt in seinem Vortrag drei Multiple-Choice-Fragen, die zeigen, wie unser Weltbild oft von Vorurteilen und Fehlinformationen geprägt ist. Er verwendet Daten und Graphiken, um zu demonstrieren, dass die Anzahl der durch Naturkatastrophen verursachten Todesfälle im letzten Jahrhundert zurückgegangen ist, dass Frauen heute in der Regel so lange wie Männer zur Schule gehen und dass die extreme Armut signifikant gesunken ist. Rosling und sein Sohn Ola führen das 'Ignoranz-Projekt' ein, um diese Fehlvorstellungen zu bekämpfen und zeigen, wie man durch einfache Faustregeln bessere Entscheidungen treffen kann.
Takeaways
- 🌍 Die Anzahl der durch Naturkatastrophen verursachten Todesfälle im letzten Jahrhundert hat sich verringert, im Gegensatz zu der gängigen Meinung, dass sie sich verdoppelt oder unverändert geblieben ist.
- 📚 Die Bildung von Frauen hat sich verbessert; im Durchschnitt haben 30-jährige Frauen weltweit etwa die gleiche Schulbildungsdauer wie Männer.
- 📉 Die extreme Armut hat in den letzten 20 Jahren signifikant abgenommen, was weniger bekannt ist als die Annahme, dass sie sich verdoppelt oder unverändert gehalten hat.
- 🐵 In einer Studie der Gapminder Foundation haben die Teilnehmer schlechter abgeschnitten als Zufallsauswahl, was auf tief verwurzelte Vorurteile hinweist.
- 📈 Die Weltbevölkerung verändert sich, wobei die Unterschiede zwischen Armen und Reichen verringert werden und mehr Menschen in die mittlere Einkommensklasse aufsteigen.
- 🎓 Bildung und soziale Entwicklung, wie das Schulbesuch von Mädchen, sind weit verbreiteter als allgemein angenommen, und diese Entwicklungen sollten in der Öffentlichkeit stärker thematisiert werden.
- 📊 Die Ignoranzprojekte von Gapminder Foundation zeigen, dass viele Menschen, einschließlich der Medien, über globale Entwicklungen nur wenig wissen und oft falsche Vorstellungen haben.
- 🔍 Um unsere Vorurteile und Vorstellungen zu verbessern, sollten wir unsere Intuition in Kraft setzen und generelle Regeln entwickeln, um komplexe Informationen besser zu verstehen und zu beurteilen.
- 🌐 Eine fundierte Kenntnis der aktuellen globalen Entwicklungen ist entscheidend, um die Zukunft richtig einschätzen und gezielte Entscheidungen zu treffen.
- 🚀 Die wirtschaftlichen Verhältnisse der Welt verändern sich schnell, und es ist wichtig, diese Veränderungen zu verstehen, um in der zukünftigen globalen Wirtschaft erfolgreich zu sein.
Q & A
Wie hat sich die Anzahl der durch Naturkatastrophen verursachten Todesfälle pro Jahr im letzten Jahrhundert verändert?
-Die Anzahl der durch Naturkatastrophen verursachten Todesfälle ist im letzten Jahrhundert deutlich gesunken und ist heute weniger als die halbe von 1900.
Wie lange gingen Frauen durchschnittlich 30 Jahre alt in der Schule?
-Frauen gingen durchschnittlich so lange in der Schule wie Männer, nahezu acht Jahre.
Wie hat sich der Anteil der Weltbevölkerung, die in äußerster Armut lebt, in den letzten 20 Jahren verändert?
-Der Anteil der Weltbevölkerung, die in äußerster Armut lebt, hat sich halbiert.
Warum haben die Schweden in der Umfrage oft falsche Antworten gegeben?
-Die Schweden haben oft falsche Antworten gegeben, weil sie von vorschnellen Vorstellungen und einer unzureichenden Kenntnis der aktuellen globalen Entwicklungen beeinflusst wurden.
Was ist das Ziel des Ignoranzprojekts von der Gapminder Foundation?
-Das Ziel des Ignoranzprojekts ist es, systematisch gegen die zerstörerische Unwissenheit vorzugehen und die Öffentlichkeit auf globale Fakten aufmerksam zu machen.
Wie hat sich die Welteinkommensverteilung von 1975 bis heute verändert?
-Die Welteinkommensverteilung hat sich von einer zwei-Hügel-Struktur (ein Kamel) zu einer ein-Hügel-Struktur (ein Einhörner) gewandelt, was eine Verringerung der Armut und eine Annäherung der Einkommensgruppen zeigt.
Was bedeuten die vier allgemeinen Regeln, die Ola Rosling zur Verbesserung der Weltsicht vorschlägt?
-Die vier Regeln sind: 1) Die meisten Dinge verbessern sich. 2) Die meisten Menschen sind in der Mitte, nicht am Ende der Einkommensskala. 3) Die Mehrheit hat bereits soziale Fortschritte wie Bildung und Elektrizität. 4) Übertreibe die Bedeutung von Dingen, von denen du bang bist, nicht.
Warum ist es wichtig, eine faktenbasierte Weltsicht zu haben?
-Eine faktenbasierte Weltsicht hilft uns, die Gegenwart besser zu verstehen und mögliche Zukunftsentwicklungen vorherzusagen, was für Entscheidungen in Politik, Wirtschaft und Gesellschaft von entscheidender Bedeutung ist.
Wie sieht Ola Roslings Prognose für die Verteilung der reichen Verbraucher bis 2035 aus?
-Ola Rosling prognostiziert, dass bis 2035 73 Prozent der reichen Verbraucher außerhalb von Nordamerika und Europa leben werden, was eine signifikante Veränderung der globalen Wirtschaftsmacht bedeutet.
Was ist die Idee hinter dem globalen Wissenszertifikat, das Ola Rosling vorschlägt?
-Das globale Wissenszertifikat ist ein Instrument, um Organisationen, Schulen, Universitäten und Nachrichtenagenturen zu zertifizieren, die eine fundierte Kenntnis globaler Fakten haben und somit informierte Entscheidungen treffen können.

📊 Statistische Erkenntnisse über globale Entwicklung
Hans Rosling stellt drei Multiple-Choice-Fragen zur globalen Entwicklung, wie der Anzahl von Naturkatastrophen-Todesfällen, Schulbesuch von Frauen und der Armutsquote. Er zeigt, dass die meisten Menschen, einschließlich der Schweden, diese Fragen falsch beantworten, oft schlechter als zufällig. Er verwendet Graphiken, um die tatsächlichen Veränderungen in diesen Bereichen aufzuzeigen, wie die Verringerung der durch Naturkatastrophen verursachten Todesfälle und die Zunahme der Schulbesuchsdauer von Frauen. Rosling betont, dass die Wahrnehmung von Fortschritten in der Welt oft von Vorurteilen und unzureichenden Informationen beeinflusst wird.
🌍 Ignoranz und die Herausforderung der globalen Entwicklung
Rosling führt das Ignoranz-Projekt der Gapminder Foundation ein, das von seinem Sohn Ola Rosling initiiert wurde. Das Ziel ist es, systematisch gegen 'verheerenden Unwissen' vorzugehen. Er zeigt, dass die öffentliche Meinung oft von vorgefassten Meinungen beeinflusst ist, insbesondere was die Welteinkommensverteilung betrifft. Er verwendet historische Daten und veranschaulicht, wie sich die Welt von einer zwei-Hügel-Struktur (Arm und Reich) in eine eine-Hügel-Struktur (eine größere Mitte) gewandelt hat, was auf eine Verringerung der Armutsquote hindeutet. Rosling fordert zu einer aktualisierten Wahrnehmung der Welt auf, um effektiver gegen Armut und andere globale Herausforderungen vorzugehen.
📚 Überarbeitung des Weltbildes durch Fakten
Ola Rosling diskutiert die Ursachen für das allgemeine Unwissen und die Herausforderungen, die dabei auftreten, um ein aktualisiertes Weltbild zu entwickeln. Er identifiziert persönliche Vorurteile, veraltete Lehrmaterialien und sensationelle Nachrichten als Hauptquellen von Missinformation. Er betont die Notwendigkeit, diese Fehlinformationen zu messen und zu beheben, indem man die Öffentlichkeit mit Fakten ausstattet. Er schlägt vor, ein 'globales Wissenszertifikat' einzuführen, um Organisationen zu helfen, fundierte Entscheidungen zu treffen. Rosling teilt praktische Tipps mit, wie man seine Intuition in einen Vorteil umwandeln kann, indem man allgemeine Regeln entwickelt, um die Wahrscheinlichkeit, korrekte Antworten zu geben, zu erhöhen.
🌐 Zukunftsprognosen und die Bedeutung von Fakten
Ola Rosling schildert die Bedeutung eines faktenbasierten Weltbildes für die Vorhersage zukünftiger Entwicklungen. Er verwendet historische und projizierte Wirtschaftsdaten, um zu zeigen, wie sich die wirtschaftliche Macht und der reiche Verbrauchermarkt von West zu Ost verschiebt. Er argumentiert, dass es für Unternehmen und Organisationen wichtig ist, fundierte Entscheidungen zu treffen, indem sie sich auf aktuelle Fakten und Trends stützen. Rosling fordert dazu auf, ein besseres Verständnis der globalen Realität zu entwickeln, um erfolgreich auf die Herausforderungen der Zukunft reagieren zu können.

Transcripts
Hans Rosling: I'm going to ask you
three multiple choice questions.
Use this device. Use this device to answer.
The first question is, how did the number
of deaths per year
from natural disaster,
how did that change during the last century?
Did it more than double,
did it remain about the same in the world as a whole,
or did it decrease to less than half?
Please answer A, B or C.
I see lots of answers. This is much faster than I do it at universities.
They are so slow. They keep thinking, thinking, thinking.
Oh, very, very good.
And we go to the next question.
So how long did women 30 years old
in the world go to school:
seven years, five years or three years?
A, B or C? Please answer.
And we go to the next question.
In the last 20 years, how did the percentage
of people in the world
who live in extreme poverty change?
Extreme poverty — not having enough food for the day.
Did it almost double,
did it remain more or less the same,
or did it halve?
A, B or C?
Now, answers.
You see,
deaths from natural disasters in the world,
you can see it from this graph here,
from 1900 to 2000.
In 1900, there was about half a million people
who died every year from natural disasters:
floods, earthquakes, volcanic eruption, whatever, droughts.
And then, how did that change?
Gapminder asked the public in Sweden.
This is how they answered.
The Swedish public answered like this:
Fifty percent thought it had doubled,
38 percent said it's more or less the same,
12 said it had halved.
This is the best data from the disaster researchers,
and it goes up and down,
and it goes to the Second World War,
and after that it starts to fall and it keeps falling
and it's down to much less than half.
The world has been much, much more capable
as the decades go by
to protect people from this, you know.
So only 12 percent of the Swedes know this.
So I went to the zoo and I asked the chimps.
(Laughter) (Applause)
The chimps don't watch the evening news,
so the chimps,
they choose by random, so the Swedes answer worse than random.
Now how did you do?
That's you.
You were beaten by the chimps.
(Laughter)
But it was close.
You were three times better than the Swedes,
but that's not enough.
You shouldn't compare yourself to Swedes.
You must have higher ambitions in the world.
Let's look at the next answer here: women in school.
Here, you can see men went eight years.
How long did women go to school?
Well, we asked the Swedes like this,
and that gives you a hint, doesn't it?
The right answer is probably the one
the fewest Swedes picked, isn't it?
(Laughter)
Let's see, let's see. Here we come.
Yes, yes, yes, women have almost caught up.
This is the U.S. public.
And this is you. Here you come.
Ooh.
Well, congratulations, you're twice as good as the Swedes,
but you don't need me —
So how come? I think it's like this,
that everyone is aware that there are countries
and there are areas
where girls have great difficulties.
They are stopped when they go to school,
and it's disgusting.
But in the majority of the world,
where most people in the world live,
most countries, girls today go to school
as long as boys, more or less.
That doesn't mean that gender equity is achieved,
not at all.
They still are confined to terrible, terrible limitations,
but schooling is there in the world today.
Now, we miss the majority.
When you answer, you answer according to the worst places,
and there you are right, but you miss the majority.
What about poverty?
Well, it's very clear that poverty here
was almost halved,
and in U.S., when we asked the public,
only five percent got it right.
And you?
Ah, you almost made it to the chimps.
(Laughter) (Applause)
That little, just a few of you!
There must be preconceived ideas, you know.
And many in the rich countries,
they think that oh, we can never end extreme poverty.
Of course they think so,
because they don't even know what has happened.
The first thing to think about the future
is to know about the present.
These questions were a few of the first ones
in the pilot phase of the Ignorance Project
in Gapminder Foundation that we run,
and it was started, this project, last year
by my boss, and also my son, Ola Rosling. (Laughter)
He's cofounder and director,
and he wanted, Ola told me
we have to be more systematic
when we fight devastating ignorance.
So already the pilots reveal this,
that so many in the public score worse than random,
so we have to think about preconceived ideas,
and one of the main preconceived ideas
is about world income distribution.
Look here. This is how it was in 1975.
It's the number of people on each income,
from one dollar a day —
(Applause)
See, there was one hump here,
around one dollar a day,
and then there was one hump here
somewhere between 10 and 100 dollars.
The world was two groups.
It was a camel world, like a camel with two humps,
the poor ones and the rich ones,
and there were fewer in between.
But look how this has changed:
As I go forward, what has changed,
the world population has grown,
and the humps start to merge.
The lower humps merged with the upper hump,
and the camel dies and we have a dromedary world
with one hump only.
The percent in poverty has decreased.
Still it's appalling
that so many remain in extreme poverty.
We still have this group, almost a billion, over there,
but that can be ended now.
The challenge we have now
is to get away from that, understand where the majority is,
and that is very clearly shown in this question.
We asked, what is the percentage of the world's
one-year-old children who have got those
basic vaccines against measles and other things
that we have had for many years:
20, 50 or 80 percent?
Now, this is what the U.S. public and the Swedish answered.
Look at the Swedish result:
you know what the right answer is.
(Laughter)
Who the heck is a professor of global health in that country?
Well, it's me. It's me.
(Laughter)
It's very difficult, this. It's very difficult.
(Applause)
However, Ola's approach
to really measure what we know made headlines,
and CNN published these results on their web
and they had the questions there, millions answered,
and I think there were about 2,000 comments,
and this was one of the comments.
"I bet no member of the media passed the test," he said.
So Ola told me, "Take these devices.
You are invited to media conferences.
Give it to them and measure what the media know."
And ladies and gentlemen,
for the first time, the informal results
from a conference with U.S. media.
And then, lately, from the European Union media.
(Laughter)
You see, the problem is not that people
don't read and listen to the media.
The problem is that the media doesn't know themselves.
What shall we do about this, Ola?
Do we have any ideas?
(Applause)
Ola Rosling: Yes, I have an idea, but first,
I'm so sorry that you were beaten by the chimps.
Fortunately, I will be able to comfort you
by showing why it was not your fault, actually.
Then, I will equip you with some tricks
for beating the chimps in the future.
That's basically what I will do.
But first, let's look at why are we so ignorant,
and it all starts in this place.
It's Hudiksvall. It's a city in northern Sweden.
It's a neighborhood where I grew up,
and it's a neighborhood with a large problem.
Actually, it has exactly the same problem
which existed in all the neighborhoods
where you grew up as well.
It was not representative. Okay?
It gave me a very biased view
of how life is on this planet.
So this is the first piece of the ignorance puzzle.
We have a personal bias.
We have all different experiences
from communities and people we meet,
and on top of this, we start school,
and we add the next problem.
Well, I like schools,
but teachers tend to teach outdated worldviews,
because they learned something when they went to school,
and now they describe this world to the students
without any bad intentions,
and those books, of course, that are printed
are outdated in a world that changes.
And there is really no practice
to keep the teaching material up to date.
So that's what we are focusing on.
So we have these outdated facts
added on top of our personal bias.
What happens next is news, okay?
An excellent journalist knows how to pick
the story that will make headlines,
and people will read it because it's sensational.
Unusual events are more interesting, no?
And they are exaggerated,
and especially things we're afraid of.
A shark attack on a Swedish person
will get headlines for weeks in Sweden.
So these three skewed sources of information
were really hard to get away from.
They kind of bombard us
and equip our mind with a lot of strange ideas,
and on top of it we put the very thing
that makes us humans, our human intuition.
It was good in evolution.
It helped us generalize
and jump to conclusions very, very fast.
It helped us exaggerate what we were afraid of,
and we seek causality where there is none,
and we then get an illusion of confidence
where we believe that we are the best car drivers,
above the average.
Everybody answered that question,
"Yeah, I drive cars better."
Okay, this was good evolutionarily,
but now when it comes to the worldview,
it is the exact reason why it's upside down.
The trends that are increasing are instead falling,
and the other way around,
and in this case, the chimps use our intuition against us,
and it becomes our weakness instead of our strength.
It was supposed to be our strength, wasn't it?
So how do we solve such problems?
First, we need to measure it,
and then we need to cure it.
So by measuring it we can understand
what is the pattern of ignorance.
We started the pilot last year,
and now we're pretty sure that we will encounter
a lot of ignorance across the whole world,
and the idea is really to
scale it up to all domains
or dimensions of global development,
such as climate, endangered species, human rights,
gender equality, energy, finance.
All different sectors have facts,
and there are organizations trying to spread
awareness about these facts.
So I've started actually contacting some of them,
like WWF and Amnesty International and UNICEF,
and asking them, what are your favorite facts
which you think the public doesn't know?
Okay, I gather those facts.
Imagine a long list with, say, 250 facts.
And then we poll the public
and see where they score worst.
So we get a shorter list
with the terrible results,
like some few examples from Hans,
and we have no problem finding these kinds
of terrible results.
Okay, this little shortlist, what are we going to do with it?
Well, we turn it into a knowledge certificate,
a global knowledge certificate,
which you can use, if you're a large organization,
a school, a university, or maybe a news agency,
to certify yourself as globally knowledgeable.
Basically meaning, we don't hire people
who score like chimpanzees.
Of course you shouldn't.
So maybe 10 years from now,
if this project succeeds,
you will be sitting in an interview
having to fill out this crazy global knowledge.
So now we come to the practical tricks.
How are you going to succeed?
There is, of course, one way,
which is to sit down late nights
and learn all the facts by heart
by reading all these reports.
That will never happen, actually.
Not even Hans thinks that's going to happen.
People don't have that time.
People like shortcuts, and here are the shortcuts.
We need to turn our intuition into strength again.
We need to be able to generalize.
So now I'm going to show you some tricks
where the misconceptions are turned around
into rules of thumb.
Let's start with the first misconception.
This is very widespread.
Everything is getting worse.
You heard it. You thought it yourself.
The other way to think is, most things improve.
So you're sitting with a question in front of you
and you're unsure. You should guess "improve."
Okay? Don't go for the worse.
That will help you score better on our tests.
(Applause)
That was the first one.
There are rich and poor
and the gap is increasing.
It's a terrible inequality.
Yeah, it's an unequal world,
but when you look at the data, it's one hump.
Okay? If you feel unsure,
go for "the most people are in the middle."
That's going to help you get the answer right.
Now, the next preconceived idea is
first countries and people need to be very, very rich
to get the social development
like girls in school and be ready for natural disasters.
No, no, no. That's wrong.
Look: that huge hump in the middle
already have girls in school.
So if you are unsure, go for the
"the majority already have this,"
like electricity and girls in school, these kinds of things.
They're only rules of thumb,
so of course they don't apply to everything,
but this is how you can generalize.
Let's look at the last one.
If something, yes, this is a good one,
sharks are dangerous.
No — well, yes, but they are not so important
in the global statistics, that is what I'm saying.
I actually, I'm very afraid of sharks.
So as soon as I see a question about things I'm afraid of,
which might be earthquakes, other religions,
maybe I'm afraid of terrorists or sharks,
anything that makes me feel,
assume you're going to exaggerate the problem.
That's a rule of thumb.
Of course there are dangerous things that are also great.
Sharks kill very, very few. That's how you should think.
With these four rules of thumb,
you could probably answer better than the chimps,
because the chimps cannot do this.
They cannot generalize these kinds of rules.
And hopefully we can turn your world around
and we're going to beat the chimps. Okay?
(Applause)
That's a systematic approach.
Now the question, is this important?
Yeah, it's important to understand poverty,
extreme poverty and how to fight it,
and how to bring girls in school.
When we realize that actually it's succeeding, we can understand it.
But is it important for everyone else
who cares about the rich end of this scale?
I would say yes, extremely important,
for the same reason.
If you have a fact-based worldview of today,
you might have a chance to understand
what's coming next in the future.
We're going back to these two humps in 1975.
That's when I was born,
and I selected the West.
That's the current EU countries and North America.
Let's now see how the rest and the West compares
in terms of how rich you are.
These are the people who can afford
to fly abroad with an airplane for a vacation.
In 1975, only 30 percent of them lived
outside EU and North America.
But this has changed, okay?
So first, let's look at the change up till today, 2014.
Today it's 50/50.
The Western domination is over, as of today.
That's nice. So what's going to happen next?
Do you see the big hump? Did you see how it moved?
I did a little experiment. I went to the IMF, International Monetary Fund, website.
They have a forecast for the next five years of GDP per capita.
So I can use that to go five years into the future,
assuming the income inequality of each country is the same.
I did that, but I went even further.
I used those five years for the next 20 years
with the same speed, just as an experiment what might actually happen.
Let's move into the future.
In 2020, it's 57 percent in the rest.
In 2025, 63 percent.
2030, 68. And in 2035, the West is outnumbered in the rich consumer market.
These are just projections of GDP per capita into the future.
Seventy-three percent of the rich consumers
are going to live outside North America and Europe.
So yes, I think it's a good idea for a company to use this certificate
to make sure to make fact- based decisions in the future.
Thank you very much.
(Applause)
