Hans Rosling, with his famous charts of global population, health and income data (and an extra-extra-long pointer), demonstrates that you have a high statistical chance of being quite wrong about what you think you know. Play along with his audience quiz - then, from Hans’ son Ola, learn 4 ways to quickly get less ignorant.

Sleep well, Mr.Rosling. Thank you for your contribution to human civilization.
glad he won't wake up again
@@lepetitchat123 wtf?
@@lepetitchat123 usually, when people die, they don't revive.
except rosling. he is the messiah. the christ. and he has risen again.
?????? yeah no i dont get it.
actually, he might be referring to zombies. I'd agree. A zombie rosling would just be disrespectful...

refreshing to hear a speech with optimism about the future for once.
Most of Hans Rosling's talks have a great positive takeaway, based on hard numbers. Now you can doubt the sources of the numbers, but the general improvement of life quality around the world cannot be denied. Also his sword-eating talk was awesome :)
ww3 here we come, keep pretending like things are going great, I''m sure it''s totaly going to happen.
Watching humans obsessed with unchecked human progress/growth while in denial of who they truly are and the negative impact they make is really excruciating
What about inflation? Looks like it's totally ignored when discussing the poverty/extreme poverty line. Surely if a person made 1 dollar in 1975, he could buy more food with it then than he can do now.. who's to say inflation didn't move faster than the poverty line suggested by the world bank?
It’s not optimism. It’s the reality.
Simple rule of thumb: when Rosling asks a multiple choice question, always go for the most optimistic answer.
Indeed, but it doesn't work on the full test: www.gapminderdev.org/ignorance/ignorance-test/
They made it a bit harder than that.
My rule is always select which is weird. If question is weired then answer should be weired
Always go to the opposite direction from the media.. That is going to be my rule now.
I tried that on Gapminder once. Only a third of that questionnaire had optimistic correct answers.
For most questions. There was a question about what percentage oil contributes to global energy consumption and the correct answer is 80% but that'd be common sense

My favourite Swede and professor of them all. So happy that I had the pleasure to meet and learn from him. The one and only, Hans Rosling. R.I.P dear professor. 🙏
R.I.P. ""We are extremely sad to announce that Professor Hans Rosling died this
morning. Hans suffered from a pancreatic cancer which was diagnosed one
year ago. He passed away early Tuesday morning, February 7, 2017,

Foundation said in a statement." TheLocalSweden
I am sorry and bummed . He clearly was a great contributor to understanding
Oh, that's too bad...

Videos like this remind me how much I love learning.
+Frosty yep perfect , its supposed to do that, now can you tell me what it taught you that you didnt already know ?
+Frosty watch again if you could, i havent seen it, humour me please , im conducting a very interesting experiment.
please attempt if you can to allow me the pleasureof learning what you just did from this video. The experiment involves the efficacy of the speaker to expound hius concept in that it might be then transferred.
+deadprivacy It taught me that not only is my own understanding of reality flawed and guided by personal bias, but that it's also very common among 1st world educated people, our cumulative ignorance goes a long way to spreading mis-information and how that might inform us into acting in ways which aren't congruent with reality.
*****
then why was he doing just that, whats your personal bias? as i said utterly vague bullshit for dont believe everything your told.
+deadprivacy My personal biases are pretty much what he explains in the video. He actually polls people and measures how ignorant they are on these topics, when we get scores which are statistically worse than simply guessing it means we have biases we need to address, if we simply didn't know and we guessed the answer you'd expect a distribution of answers approximately equal to random chance (the chimps). Maybe you should actually watch the video instead of waffling incoherent nonsense.
I discover Mr. Rosling Senior today, the very next thing that comes to revelation is that he is no more. RIP sir, you will be missed.
I read his book this week. „Factfulnes“ im more positiv now. I read a lot, but this was lifechanging. Everyone should read this
Just died today.. so sad. Rest in peace..
RastamanBob2001 watched and discovered this video because of his death. Really, really sad. Hopefully, his work doesnt go wasted
:'(
what ???? :O
:(
He said once "Vila kan jag göra när jag dör", which means "I can rest when I'm dead". I guess he can finally rest now! : )
(Probably the only positive thing about his death though ;_;)
Drink more coffee, you can sleep when you're dead. Unless you're Norwegian Lutheran I suppose.
oh i wish hans to be alive now to hear his insights about covid 19
same thoughts here while reading his book, factfulness, published last 2018
Finally! I've waited years for another TED presentation from this brilliant man.
there are many other videos of him on youtube, just look for them :)
***** I saw him first on TED so is extra special to see him back here :)
You can hear his enthusiasm and pride in sharing the world about his findings. Shaping the way we look at the world and how we should think about the world we live in. RIP to a great man who really opened the eyes of the public in how the media disseminates information and how we as consumers can filter and think about how situations can still be bad but also getting better simultaneously.
Rest in piece Hans! May your kindness and search for truth live on. And may the way you educated us inspire others to educate.
Turn our weakness, our gift of intuition, into our strength. Love this.
I am saddened by this news... May he rest in peace and his idea(l)s spread all over the world! We need people like this to change for the best. And we will. Thank you for your work Hans, and keep going, Ola!
Deaths from disasters (as a total number) should take into account that the population has exploded since 1900, so it's even more remarkable.
Adrian another point is prices has gone way higher than back in 1900s. The wage per day might have increased but the expenditure have increased a lot more. The study is seems highly flawed.
Gapminder always adjusts the prices/income for inflation
Roli Sanjivani
Any stats worth their salt calculate in the inflation. You failed using the first rule of the humb.
I believe they calculated those obvious factors in. No real scientists would have purposely presented there work without problem proofing these numbers beforeh hands.
Adrian I was thinking that too - whether these figures had been adjusted to account for variables such as population growth and inflation etc.
“The first thing to think about the future is to know about the present”
So true!!
I am sure that the chimps would win hands down against Bill Nye the science guy.

As a teacher I know you have to be a life long learner, this means constant research and willingness to change. A teacher that teaches what he was taught is no teacher at all, they are just a conduit for antiquated information.
Real learning comes when we step out of our comfort zones and into the unknown.
WTF, why didn't the TED audience know the poverty rate has dropped drastically?
It's mentioned in every one of Hans Rosling's TED Talks!!!
I read his book this week. Everyone should read it. I read a lot, but this was life changing. I’m more positiv now
@@janiss3700 It's great that more people are out of poverty, but species have gone extinct and our planet will be at a climate tipping point within 20 years, during which time, population will be GROWING, not shrinking.
The income-scale used is logarithmic. If you look at the numbers along the income-axis (x-axis) you will se that thay are 1, 10, 100 and that thay are evenly spaced.
This is not a problem in it self, it is a rather standard procedure to use logarithmic scales when presenting data that behaves exponentially. The problem is that, in this case, the grafic representation of the data becomes missguiding. It makes the incomedistribution seam less unequal than it really is and it especially missrepresents movements allong the scale (such as the "humps merging") by making movements at the top of the scale appear smaller than thay are and making movements at the bottom of the scale appear bigger than thay are.
A logarithmic scale linearises exponential relationships and thus makes it easy to observe relative changes. Ola Rosling, however, uses this scale to show absolute changes and it is therefore missguiding.
MrDamnnogoodnameslef to be a little fair though, that first dollar in income is worth a lot more than the second dollar of income. Like, if I win a million dollars on lottery, I will be SOOOOO happy. If I after that win another million dollars in another lottery I won't be nearly as happy as I was when I won the first one. 10 million dollars would probably make me as happy.
snuffeldjuret I agree that disposable income has deminishing marginal utility, i.e: the second million gives you less pleasure than the first one. That however does not change the fact that the grafic representation of change in the incomedistribution become missguiding when a logaritmic scale is used.
MrDamnnogoodnameslef
sure, if you want it to look the way you describe =).
+MrDamnnogoodnameslef Very good point, I totally agree with that, but if it helps people remember the main idea it looks fine to me. They never pretended that everything was good, just that the tendency wasn't what most people though.
I was so sorry to hear about the passing of Professor Hans Rosling, but I'm really glad to find this video which seems to suggest his son will carry on his good work.
I'm conflicted. As a Norwegian, I'm programmed to think that the greatest fools on the planet are Swedes. On the other hand, as a European, I'm programmed to think that it's Americans. It rarely comes to a point with a direct comparison. Americans definitely came closer to the truth than the Swedes. However, they also got a result closer to random. So, what's worse? Not following the news and be right by random chance, or following the news and be consistently wrong?
P.S.: Don't worry about the apparent anti-Swedish prejudice. Scandinavia was at constant war, until 205 years ago, when we started making fun of each other, instead. Since then, only jokes and insults have been fired across the borders. As for the apparent anti-American prejudice... Well, I'm just human. When a target gets too tempting, I start shooting -- but only insults and jokes.
Having more people choose the right answer with it being closer to the random 33% does not mean it was because of more randomness.
@@minecraftminertime That's true. However, it also means that you can't conclude that there was any other cause than randomness. The circumstances must also be very peculiar for it not to be random. A proportional number to those who answer right for the right reason must answer wrong because they've been deliberately (not coincidentally) misinformed. There's a very high probability that most of those who answered right did so randomly.
Most importantly, though, I was joking. Well, I was joking when I insinuated that Americans and Swedes are particularly bad. The likelihood is that the rest of the world is just as bad, including my own country. What I said about Swedes and Americans could be said about anywhere else, as well. Not both things about the same place, but one of them.
Sounds like an excuse to outright reject that they had a better score than yours.
@@AyaElizabethMaxis Well, I didn't take the test properly. The fact that it was presented in that way, tipped me off to the fact that it was expected that the majority would be wrong. Otherwise, what would be the point of presenting it like that? As a result, I did fairly well. How I would've done in a proper test setting, without a clue about what results were expected, I have no idea. I'm a contrarian by nature, though, which might have helped me.
When a target gets too tempting you shoot? I am glad that i am not american, i ve never had a temptation for school.
I wish this video went viral. Especially among journalists and teachers. But it won't.
sharing is caring
Where's the optimism?
JetBlackGT
You are right, I should have learned from the video! I should have a bias for thinking that things are improving! My error! :)
I got to know about this person by a teacher of mine. It's definitely happening somewhere.
My professor shared this video in my stats class
Rest In Peace, Mr. Hans. Thank you for spreading the knowledge and awareness to the world. Today i finished reading your book Factfulness and i feel really glad that i read it. Fully changed my way of seeing the world. You brought so much awareness of data and thank you for reminding us to look at facts and not just believe our intuitions. I have a high hope about a great and united world. Thank you so much. Love.
Excellent and exceptional presentation, the Roslings are brilliant in understanding the simplicity of man. Facts are universal and opinions are subjective, I am deeply motivated to increase my insight and knowledge, my humble gratitude.
it makes a change to laugh the same way the audience laughs, like I feel that the engagement is very universal, beyond just the live viewing, it certainly brings that sense of a genuine performance, rather than just a clinically rehearsed presentation. Great video.
what would be a really interesting idea is if instead of using those bits of information to make a global awareness test, it was used to make a new criteria for journalism. This would change the question of "what is the most sensational bit of news " to "what is the most (objectively) important bit of news".
the objectivity of news can a lot of time be down to if the news is for profit or not tbh
the objectivity of news can a lot of time be down to if the news is for profit or not tbh
I'm pretty sure their approach making a Global Awareness test is MUCH more comprehensive. It would affect Journalism as well as everything else.
@@xanuui Only if news organizations were legally required for you to pass on it. It also doesn't make the news corporations stop giving out useless information for views, winning the economy war against their (any) legitimate news competitors. If the news can go for bigger dollars, why wouldn't they?
RIP Mr Hans, this was extremely interesting and he seemed like an amazing person. Sadly this is the first I've heard of him, but I'm glad some of his words have been preserved in video.
I could listen to this guy talk all day. He reminds me of the professor who's always high on caffeine from RWBY.
now you mention it i can totally see that!
Why is their a Rooster Teeth reference in the wild?
Professor Oobleck XD
As a presenter Mr. Rosling is AMAZING, he is engaging and the results he shares are very compelling. I would highly recommend this speaker and he has been added to my bucket-list to see in person. #powerful #stats #speaker #data
as my mental health dependent on the positivity of the news, i am actually touched by this ted talk ♡
I'm absolutely shocked that I got all the answers wrong. This was very eye opening
the media, deliberately or otherwise, promotes fear and gloom, if it's deliberate it's because of politics, if it's ignorance it's because they just want a job. information passage needs to be as first hand as possible, when i doubt the source i try to pretend i didn't hear anything at all.
I got 2 correct and 1 wrong, which is twice the expected result for a given shimp. Nice!
at least u know it now
It’s ok that you got them wrong
The fact you see it as eye opening is amazing
You are and will be missed Hans in this world. I wish there were a few more like you.
RIP, Hans Rosling. :-( You were a good, cheerful soul. Excellent lectures.
Love this. Going to design a workshop based on this to share with young people I work with.
Poor countries are catching up. This is what the video argues. Poor individuals aren't. This is what the video is silent about. Look up GINI coefficient and see a different side to this story.
Keshav Bhatt Hi, how is the workshop going?
Marcin Olak Poor individuals too are catching up. Look at 6:49 . There was a higher number and percentage of people living under 1$ in 1975 than in 2014. This is what the video argues.
muragan, you dont understand averages, it would seem.
Embryophagist what do you mean? Can you explain.
I am rarely impressed but this human was one whom I really did find remarkable. I called him my "Data Angel" -- someone who promoted facts from a factual POV vs a FEAR POV. When I first met him in 2010, I was giggling with glee. Watch all you can as we can learn so much from him. My sincere condolences to his family. He died far too young, and thankfully has left a real legacy.
Delightful! This and his other videos are well worth watching. Some might nitpick some of the details, but overall the guy’s spot on.
We’ll miss him!
R.I.P Mr.Rosling.
You are my teacher who teaches the fact of society.
Thank you!!
RIP Hans. One of the world's best educators.
General knowledge on the world is important.
Brilliant mind ,amazing delivery as well as captivating speech with humour as a delightful topping 👏🏽👏🏽
My heartiest gratitude for all the people who have watched the full video. You are not indifferent. You made it to the mark!
I bought his book one day after looking at the bubble graph in the front cover. As I read it, I was thinking, "wow, I really want to meet this guy". Imagine how sad i was when i got to the back and saw that he died in February 2017. RIP my dude. You made stats fun.
this made my day, my week, my month and my year!
Great presentation with lots of humour, facts and the deeper insights into our global ignorance about several phenomena - with media people themselves leading the ignorant crowds!
Now we begin to understand why we are lacking basic knowledge about the true states of certain problem areas which grab headlines but don´t give us the truth....
highly recommendable TED speech from a great university brain and his son from Sweden!
Favorite human being. He continues to change lives
I loved his book 'Factfulness'.
It's amazing.
One of my favourite reads of 2019.
Factfoolness maybe ? Did you physically , by yourself check all the facts mentioned in this book ? If not , the only thing you've got is belief purely.....
SaNLeX771 1 no, the book is actually called factfulness
My favorite book of all time tbh
I read it last week. I read a lot, but this was lifechanging. Im now more positive and I would hope that everyone read it
@@janiss3700 What's the positive spin to major rivers drying up simultaneously all over the globe and in very important breadbasket regions? I want to be positive about massive crop failures all around the world.
The old guy is a great speaker, especially for a public official
Recently, i'm reading the book, Fact, written by Hans Rosling, and i intentionally search for this video to expand my knowledge. Mr Rosling is a person i deeply respect for. In my view, i am shocked by their value and will keep this value in my future
I'd love a 2021 update on this. What an epic explanation.
What a legend, such a novel way of speaking and presenting important information!
Rest In Peace, Hans
He is a master of presentation - love it!
6:05 I love this guy so much.
His son is just as entertaining and knowledgeable really enjoyed this video
Love the way the comments just show more and more continuing bias and ignorance - personal bias, wrong facts, bad data, news bias...TOP TIP: watch the whole video before commenting
I can't stop watching these videos! Hans is AWESOME
Alltid lika fantastisk och roande i sina föreläsningar 👍
I think his survey is a good example of why it is easy to write surveys that give the results you want (and he might have wanted it to come out that way), nearly as easy to write a survey that produces meaningless results (which is the benign case), and quite hard to write a survey that provides deep insight (in this case, into what people know about reality).
The problem I had with all three of the questions was that they were worded in absolute terms about relatively changing matters. He asks how many people died, but the population now is MUCH larger than before, so it is hard to believe that the absolute number is so greatly decreased even if you are sure that the percentage has decreased. Similar rationales apply to the other questions.
As a rhetorical mechanism to involve the audience, perhaps good, but I don't like trick questions or feeling like I was tricked. Yes, there is long-term progress, but we don't get to live on the long term.
P.S. Apparently this comment is annoying (or has annoyed) some people, so I think I should attempt to clarify why I was annoyed by his introductory survey. I'm tempted to change one part, but that might confuse matters, so I'm just adding this postscript to it.
I parenthetically noted "(and he might have wanted it to come out that way)", but upon reflection I think that is too soft a wording. Rather I think he did not merely want it to come out that way, but more likely that he deliberately tested his questions and attempted to word them in ways that would produce the results he wanted. In other words, I think he was approaching Sophistry. On the one hand he ostensibly opposes ignorance, but on the other hand he is trying to make his audience feel as ignorant as possible, apparently to pique their interest through his manipulations of the survey.
I'm not particularly questioning his sincerity. I even believe that TED tries to get sincere speakers and would not invite a speaker they regarded as insincere. I hope they have a good 'sincerity vetting' process, too. I am questioning his speaking tactics and attempting to explain why that specific tactic was ineffective in my case.
It isnt relatively changing, there is a clear trend. And so what if we don't get to live in the long run? We still have to work for a future even if we won't be part of it.
You can argue the semantics of how the questions were asked, the question didn't trick anyone, people tricked themselves.
+Shannon Jacobs It would be better that instead of pretending to be smarter than everyone else and that you were tricked into being wrong, you simply admit that you were about as ignorant as the rest of us, give or take a bit, and actually embrace learning something and reducing your ignorance. In a world of specialized knowledge the vast majority of us are ignorant about the vast majority of subjects, we should at least be smart enough to acknowledge that.
+Shannon Jacobs This is the pettiest comment I've seen this month.
+Shannon Jacobs I think being wrong is your shark.
My main comment is that I don't pay a lot of attention to Google Plus. Also, my memory of the video in question (probably a TED talk) is quite fuzzy. I think he had some good points, but his sales pitch was not good. Manipulative? Progagandistic? Whatever it was, it mostly negated or reduced my interests in his substantive points, making them less memorable though I'm confident that was not his intention.
On the general topic of ignorance, I actually feel like I'm amazingly ignorant, but when I compare my ignorance to other people, they mostly manage to surprise me by being even more ignorant. People mostly seem to believe whatever they want to believe, and damn any contradictory evidence.
Narrow-minded specialists may be the most ignorant of all, as though they have dug themselves so deeply into the pit of their expertise that they can't see any landmarks or orient themselves or their specialized data to anything in the real world... My own problem is that I'm excessively shallow, but at least I have a bit of breadth. I think. For what little that's worth.
Now for the question of making "good points" on Google Plus, you may reference the first paragraph of this reply comment. Maybe it could be fixed, but the google is too EVIL these days to fix anything that doesn't make money. LOTS of money, and as FAST as possible. Details of possible fixes available upon polite request, but significant effort on my part is contingent upon your ability to convince me you could do something with the fixes.
From an ekronomic perspective, I don't have the time. Too bad no one does. We fall back on economic models, eh?
If you guys haven't read his book 'Factfulness', please do. This gentleman had spent his life helping those less fortunate than himself and the Lord knows there were many. His book aims to dispell myths that are so entrenched in our minds and show us a world that's getting better.
Like that father and son duo is just dope. Really props!
Great talk! We need this information that is gathered over time and not just todays news.
This is truly the king !!
Rest in Peace , Hans.
one of the best TED talks yet!
Great talk! It's interesting to see how they framed the hump by using a logarithmic scale instead of linear scale. While this doesn't change the conclusion of their talk, it does show how facts can be 'massaged' to show a certain perspective. It's a great time to be alive to be able to nitpick about these kind of details!
What a Genius❤️
Apart from the great points they made in the conclusion, I also believe it helps us sleep easy - just the comfort that everyday when you go to bed, the world will be a slightly better place when you wake up. It might seem small, but it's improving nevertheless
Sixth Mass Extinction Event in Earth's history is very positive indeed. Mass death, war, famine and disease is what makes me happy.
That was excellent. Fun, funny, informative, thought provoking. Thank you.

Great video! Hans Rosling is so engaging and entertaining to watch
Very enjoyable and informative. I'd have loved to have Hans as a professor in university!
The statistic on wealth is a logarithmic hump, not linear, so it isn't easy to see that the wealthiest people own more, or 90% of all money. The upper middle class and below have more debt, like car payments, student loans, and mortgages, so they have negative net worth.
He is/was a statician and knows about scale. Are you implying he is trying to deceive the audience ?
Logarithmic scales are not good for this kind of "show the public" graph. It's hard to get your head around them in a short clip.
yes but that wasn't the point of the statistics. they were focused on the majority and how is their life.
@@dsdsspp7130 do you know what proportional means ?
thank you for your great book :) read it in one day, truely inspiring!
i think this proffessor is amazing and he is very good to explain. i love him. But the world can never be measured nor explained by statistics. and yes you can find alot by doing that. but it will never be 100%. no information can ever be that. information will always grow and expand. thumbs up, great guy, both of them.

So true!

Lots and lots of people should watch this, including one of the most powerful man in the world and all of his supporters!!!
Being dismissive of libraries is sinister. Books have a published date on them. As long as you contextualise them in this respect they become party of scientific history. The Arts are history and books and context can only be found in books; they are a physical manifestation of their time and the ideas of that time.
And, of course, if you find a book published in, say, 2010, it's still more up-to-date than a book published in 2000. Sure, not as up-to-date as a book from 2016, but still pretty up-to-date.
REST IN PEACE HANS

Incredibly interesting and an amazing way of presenting!
