What shapes our perceptions (and misperceptions) about science? In an eye-opening talk, meteorologist J. Marshall Shepherd explains how confirmation bias, the Dunning-Kruger effect and cognitive dissonance impact what we think we know — and shares ideas for how we can replace them with something much more powerful: knowledge.

      Hi, I’m Charlie Ladrona Bangtan-Scott on Facebook. I’m from the Philippines. +Van Tien Nguyen

    • Watch more Netflix bro.

      “I am Vietnamese” or “I am from Vietnam”*

      Vietnamese is your language or nationality. Vietnam is the country you are FROM.

      English is both a genius and idiotic language. It has nonsensical rules but once you are proficient, I’m not sure that there exists another language that allows for such complex and specific communication through the spoken word. Good luck, I am glad I didn’t have to learn it as a 2nd language.

      EDIT: I had to edit this comment 3 times for “proper” English. Case in point.

    • You are from Vietnam, or you are vietnamese; you mixed the structure there 😉

      As said above, watch things with subtitles and look up the lyrics of english speaking music that you like. That should help a lot. Translated books (the ones that have one page in english and one in your language) are very helpful too.

    • I could teach you.

  4. •G Dragon;
    • Jimin;
    • Jisoo;

    • Ceci. that’s what i thought because in the background of the thumbnail, it said *uga* but i thought it said *“suga.”*

  5. If u listen to kpop you will understand the confusion with bias, *damn it*

  6. oh TED knows about bias very well…

    • Did you even watch the video my dude? Drop that confirmation bias that lets you deny every other resource, check yourself.

  7. first ted talk i’ve watched in 2019, and this was pretty good. definitely thought provoking.

    • ​+mathijs How can I attempt to understand his perspective with “Meh”? That’s a very silly viewpoint, but thank you. I am well aware I wasn’t being super mature, but at least I got something from the video and it seems I got a reply from him that DOES explain, so I think I did fine. Thanks for your non-contribution.

      You replied while I was typing
      Hold up

      Frankly I think ‘meh’ is concise and straight forward.

      You wanted a deeper explanation and you got one.

      Im still curious what exactly you meant by ‘high potential human being.’

      You appear to have a lot of frustration in your life as you are very quick to attack people.
      Are you OK?

    • +Morty Sanchez I think anyone who HAS perspective and life experiences to demonstrate something from it can talk about it, plus he did his homework. The fact that you think he’s a meteorologist so of course he has nothing to contribute because pretty obviously Dunning-Kruger is a bit sad.
      Rating it “Meh” because you already knew everything is not intelligent in my opinion because perspective is something very fluid and it’s not bad to remind ourselves about the things we know. If you’re so smart when it comes to psychology you should be aware there is a big difference between simply knowing something and being MINDFUL about it.
      What I meant? Rating “Meh” without any context what so ever is frankly dumb is what I felt. It adds nothing. You said nothing about your perspective which made the impression that you thought his message overall was “Meh” which it certainly wasn’t.
      The subject if you’re intelligent enough to apply it to many things in society, perhaps above all mass media propaganda, is very important. Being self aware of the type of bias we have and try to improve our knowledge and understand other people’s perspective is something desperately needed in this world and nothing to scoff at.
      That’s what I meant, but thanks for the context-adding reply which was not dumb in any way and I can see why it would be kind of boring when you have a lot of pre-existing knowledge on the subject. Happy new year to you and your loved ones. Peace!

      I explicitly made it clear that being a meteorologist doesnt mean he can’t contribute.

      Cheers
      Happy New Year

  8. Nice, thanks. More talks on cognitive bias & logical fallacies please

  9. I want more of those NASA forecast

  10. Why does the public not trust science? From the experiments on the world without the people permission, to the classification of information for more big market manipulation.

    You do not have to look far and wide for reason why people are having trouble trusting the suit, even if you have removed the tie.

    Much love brother. Good talk. ✌️

    • The short answer is, because science doesn’t produce clicks.

    • Pierre Delapotterie // 2nd January 2019 at 9:15 pm // Reply

      Scientists are humans too, are you asking to blindly trust people?

    • Because all governments lie. Governments are the biggest mass murderer in history.

    • +Pierre Delapotterie That one comment pretty much summed up your ignorance of how science works. “Blindly trust people” has NOTHING to do with how science is done. We don’t take people’s opinions, we rely on their data, their evidence. Then it is continuously & rigorously tested over & over to either disprove or solidify their results. The scientist, or individual, has nothing to do with the WHY we trust science.

    • Pierre Delapotterie // 2nd January 2019 at 10:25 pm // Reply

      +Cookie Nibz That’s not it, being human, there is no guarantee that a person’s work, in this instance a scientist’s findings are 100% true, it could be false or it could be misleading. That’s why it’s not enough that a scientist is declaring something for people to trust them, you’ll have to convince them.

  11. I was expecting something about confirmation bias based on the title and stopped watching as soon as I got the answer I was looking for.

  12. facts dont care about your feelings!

    How dare you accuse me of bias! I am a 100% objective observer!

  14. thegeneral123 // 2nd January 2019 at 4:14 pm // Reply

    Answer, because less educated people are less able to academically and dispassionately evaluate things.

    • Nestoras Zogopoulos // 2nd January 2019 at 5:03 pm // Reply

      For some the bias comes because of their academic performance

    • Rabi Halawani // 2nd January 2019 at 5:09 pm // Reply

      Nestoras Zogopoulos true

    • Rabi Halawani // 2nd January 2019 at 5:11 pm // Reply

      I also feel it’s because of the heavy flaws in the education we are given, it teaches us bias facts depending on the place/ country you are taught in. Sad, really

    • @thegeneral I’d say less educated and intelligent but I fully agree. I used very much a scientific and academic process of analysis and logic several years before I ever attended University and would have kept doing it regardless or academic studies, but that absolutely doesn’t apply to everyone. Academic education or at least learning and always applying the scientific process is super important.

    • Well-educated people are pretty terrible at this as well, to be fair.

    Good talk, but we still need some “TED’s basics” playlist for talks that do not contain anything specific
    Or it’s just me, I dunno

  16. Tell people climate change is good for them and they don’t have to change their behavior in any way and they will immediately believe you.
    No one takes issue with quantum mechanics even though it’s so mind blowing. Why? Because they don’t see it as a threat to their lifestyle.
    People will only accept things that don’t require them to do much. If they have to do something, there must be something in it for them. That’s why climate change is such a though sell.

    -“Science isn’t a belief system.”
    Also
    -“87% of scientist believe in global warming.”

    • i am really surprised the % was that low you would think it should be 95%

    • yeah the left don’t get into industry they get into the institutions like education health care and government so they need a way to fund their institutions and so obviously almost all of them agree on the science. things get tricky when you disagree with the orthodoxy.

    • “87% believe that climate change is mostly due to human activity”

    • I had an issue with that first statement myself. Science IS a belief system, although it’s supposed to be an evidence-driven one with specific standards. A single scientific study shouldn’t dictate your beliefs, although its evidence should inform and perhaps adjust your beliefs. In the case of climate change, there is a wealth of evidence supporting its reality, so it’s far less reasonable to doubt it (that said, there’s less certainty about specific long-term effects, how to address it, and so on).

      Don’t misquote just to fuel your bias, thats literally an aspect of his argument in this video

  18. there’s a huge difference between ‘humans are contributing to climate change’ and
    ‘humans are causing CC’.

  19. and the next “scientist” babbling about how humans are the reason for climat change without giving any shred of evidence. the very thing he accuses the common people is his own biggest fault, he does not understand the difference between climat and weather.

  20. 1:10 “Science isn’t a belief system”
    2:35 “87% of scientists BELIEVE that humans are contributing to climate change”

    Conclusion : 87% of scientists accept a belief system that is anti-science.
