How not to be ignorant about the world | Hans and Ola Rosling

Spread The Viralist

How much do you know about the world? 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.

About the Author: TED


  1. My heartiest gratitude for all the people who have watched the full video. You are not indifferent. You made it to the mark!

  2. I read this professor's book Factfulness. I got to know him from there and came to see this video.
    Until now, I myself thought I knew about the view of information and the truth about the world.But the truth I was seeing was fiction. It was thanks to this video that I was able to notic this.

  3. I can't help but notice Rosling has no rosy projections for climate change, sea level rise, or the loss of river delta farmland to saltwater incursion…

  4. I applied the rules and I nailed the certificate in 3 tries. I missed two questions, both questions where good VS bad was not as clear cut.

  5. I think this was basically the AICE program for me, it taught me a lot about the world.
    Advanced International Cambridge Education (AICE).

    This is also the same thing I believe the Honors program in colleges try to do.

  6. I scored 55% on the worldview quiz in their book 'Factfulness', but only because I had read a few months before Steven Pinker's book 'Enlightenment, Now' which contained a lot of information about the improvement in the human condition in recent times. If the 20 riches countries would contribute only <1% of their GDP toward poverty mitigation projects, we could end extreme poverty in the world by 2050 or before.

  7. The extreme poverty statistic is dangerously inaccurate; it comes from the World Bank, whose notions of what constitutes extreme poverty is extremely misleading. Let's not trust the banks on poverty!

  8. Terribly enthusiastic audience, or is that my Britishness kicking in… they clapped when Rosling picked up a pointer!? Great talk, thank you. I read the book about a year ago but had forgotten its importance.

  9. I see misrepresented data, the difference between 1 and 10 is the same as in between 10 and 100? That's where the valley between the hump is

  10. Concerning Ignorance: Pick any subject and you will find (as I have the physics professor) that most people don’t mind being ignorant. In fact, they prefer it. Fortunately, I’m not like most people.

  11. Ok. But this man and others should be confronted by other experts . I would like to know precisely the sources of his statistics !

  12. I live five years before stalins' rule, and I assume "things will probably improve". Now can we just shoot these idiots and the audience that applauds them, thank you.

  13. How is it not obvious by these ridiculous answers that the more elite you are (like attending a TED Conference) the less you know about anything.
