  1. what is it with this guy? or worse what's is it with the audience not standing up and leaving. Its all about the bucks. People with money hang out with people with money. That's it.

  2. That time limit that they're bound to sucks. I would always like to hear more from these ppl and it looks like they're willing to tell more, but due to the time constraints, wrap it up in a hurry.

  3. @ponygutz I literally just had that yesterday and the day before lol. I got a good laugh when he said that

  4. This whole thing thing seems like bullshit. Although i hold to his conclusions he can't seem to justify them, the closest he gets is by odd analogies. But analogies don't justify.

  5. This guy is doing interesting work, but he thinks categorically,not mechanistically or creatively and is not that insightful. He must be an MD.

  6. excellent video! great speech. the world does need more connections, and unless some global catastrophe happens, global interconnection will inevitably proceed.

  7. The strength of each connection I feel is something that was not covered in these models and in this methodology. I feel this is essentially important.

  8. Very insightful…love it. It kind of relates to what Dr. Wayne Dyer says about people and their relationships with others…viewing oneself as part of a whole…or "higher network" if you will.

  10. This guy's right. More social connections are a good thing. I saw a study that said people with more close friends live longer and happier. I used to live in the US and its difficult to meet people there: people look at you like you're crazy if you dont know them and start talking to them. I live in Europe now and its a lot easier to make new friends here.

  11. great conclusions, I thought it was going to be some bs talk about social networks on the internet, but was very surprised. good stuff

  12. @Invaishir : omarly666 He does have a point though.

    I'd disagree that aggression and violence cuts ties especially where politics, religion and business are involved but I'm not trying to twist his words. You could replace the word "obesity" with any word, say "bigot", and the results, I reckon, would be very similar. His argument is positive if not a bit simplistic. Maybe he should have had more time. He seems a bit rushed.

  13. @bavwill He's right though in one sense about getting connected. It creates more options, helps to expand people's awareness of things and softens some people's fear of different lifestyles.

  14. @Ikar1 and if you see a clown on the street? like an art or acting student? It is supposed that there are some mirror-neurons (neuronas espejo) that throw the smile like a reflex.

  15. @vraciudude Take into account, the use of electronic communication, especially the use of texting as a substitute for personal interaction. The use of emoticons suddenly serves as a direct link to our emotions and how we feel about certain situations. It is as if we have neglected the need of personal communication and found a way to replace it by electronic communication. Facebook, texting, twitter, email etc all fall under this.

  16. @trentschirmer
    instead you have people sqrewing each other over like it was some kind of sport…..10 years and no-one can agree on what to build on the twin towers site….meanwhile Dubai has built a whole City…..i digress

  17. @Ikar1 It's also natural for us to try to kill each other too. Try smiling. then you won't get bits of bone and brain on you…..

  18. @vraciudude funny, most of the people in my facebook were or still are REAL friends
    in a real life. thats why there is 200 not 2000

  19. Does it mean that if get fat Facebook friends you will get fat too?
    How about other diseases and addictions? Do they spread by text messages?
    How positive qualitys spread relatively to negative?

  20. @Ikar1 perhaps the barrier of feeling personal threaten should be solved before all the mirror neurons enter the game. If you smile in front of a baby it smiles as far as I tested. It detects eyes+your teeth and reflects. There is a video in youtube called "monkey see monkey do" that explains it. If I say in my office, family or friends "I want to tell you something… " while smiling and self interrupting me they do return a smile. Of course that the stress inhibits that.

  21. obesity, 1st Visible sign of the general breakdown of our health. as acid rain had trees die back in the '80's. Trees that lived to 500 years when we first came to this land now are lucky to survive for a hundred years in the city. Most die from a disease, fungus carried by saws and clogged pores. We are as sick as the distance we live from nature's green belts, compounded by the trail of our toxic exhaust
    Like wise I

  22. @freshhug actually, there's a difference whether you think you know something, or you made a study and know something to the extent the study covers)

  23. @besionishe
    Yeah.., you can proove it to others. But in the word "think" as YOU put it here I incorporate having proof for your own self.

  24. @imanuel2012

    You're wrong here. Everyone is connected to the social networks, and everyone will be affected when a phenomenon waves through it.

  25. @liberationn15
    Hence why he mentioned the three ways it could be interpreted, with only one (induction) implying causation. He followed this up by saying there was evidence of each at play, although he didn't go into details.
    People trying to be smart overplay the "Correlation does not imply causation" card to the point where they seem to believe correlation never coincides with causality, which is clearly far from the truth. Don't fall into that trap.

  26. This is how true collaborations work, the connection between collaborative groups are fundamentally different to the connections between co-operative groups,

    There's a lot of merit in the argument that what the world needs is more connections, and it definitely needs a more collaborative spirit.

  27. One would ask if you could identify certain hosts that the world actually revolves around. Then kill them and hopefully the mass of humanity will die. Sigh… one can only wish.

  28. I've watched this all the way through and I've just realised he's talking about conformity, a well-documented phenomenon. But because he doesn't participate in communities that do study conformity, the phenomenon is new to him and he's inventing a new model unnecessarily. Inventing terms such as 'confounding' and 'interconnections' cloud comprehension.

  29. 14:50 Leave it to a nerd to use the molecular structure of minerals as an analogy for how the structure of social networking effects the properties of social groups.


  30. Interesting, so now we know…I am keeping millions of people happy and positive. How do we create a system where they pay me?

  31. It would be a shame if you did not shed fat when other normal people do it so easily with Fat Blast Blueprint (check it out on Google).

  32. isn't being shy a result of education and influences from outside rather than a result of genes? is it really as obvious as he claims?

  33. If you read his book ''Connected'' (which I strongly recommend) you will see that all the characteristics that designate someone's personality depend both on the genes that inherits from his parents AND the social network in which he/she lives and acts.

    Nicholas Christakis  PLEASE clarify this: this could mean so much that it starts to mean nothing again.

    To make this clear: this is everything else than clear:
    13:28      'explained by our genes'

    1.)genes don't explain we explain by genes.
    2.) 3 INTERPRETATIONS of the sentence at

    A) The behaviour of how I & people whith my set of genes network (transitivity, number, centrality) has a variation. [3 variables which vary in the populatoin of my gene set]

    B) I & people whith my set of genes network ((transitivity, number, centrality)
    over the course of their live with a variation in these behaiours.
    [3 variables which vary over the lifetime]

    C) with around 50% accuracy of all variation cases it is possible to link networking behaviour to the set of genes.

    3.) a) PREMISE & b) FINDINGS are very hard to understand.

    a) the variation has a finite set: this is the 100%
    [A) normal distribution:some gene sets vary in +/-4friends, some in +/-10-25friends]
    [B) normal distribution:gene sets lifetime behaviour varies in +/-4 friends]
    [C) too lazy……

    b) around 50% of this variation is determined by my genes.
    [A) my gene set explains, half the number of my firends if i have a +/- 4 friends variation over my lifetime, so looking at my genes says: +/-2 friends is certain??]
    [B) tooo lazy…. please clarify this….

    This means:
    A) 1) You should be able to observe an 'around 50% difference' in variation of these 3 numbers in every population which has a certain set of genes.
    [some have 4 some 6 friends some 2]
    2) You should be able to observe a clearly solid core of this variable numbers………

    PLEASE clarify this: this could mean so much that it starts zo mean nothing again.

  36. I just saw the Yale video and was completely blown away by the mob of angry snowflakes.
    But I'm far more fascinated that he anticipated and described the phenomena of generation snowflake long before it ever appeared on campuses.
    I also wonder if any of those students will ever reflect back on their behavior and appreciate that their outrage was learned via their social networks.

  37. As you go through life never loose the good fiends you meetAfter the death of a friend, healing in a human social network

  38. So they teach this stuff at the 'elite' institutions, along with courses like Sandel's Justice at Harvard, Haidts courses at Columbia, etc…and what comes out the other side is a bunch of twisted little fucksticks who not only cant/dont/wont comprehend these insights, but actually are so maligned as to get someone like Kristakis fired. It might be the end of W Civ we are witnessing: the media (propaganda tool), academic institutions, and political machines are all complicit. What do we do?

  39. nice, enthusiastic. as to why humans don't form networks in a shape of perfect grid: it's because the gird is a perfect creation of a designer who supervises everything and builds a grid while humans and all living creatures are down there, they see only their closest environment and just do what they can to create at least some vital bonds. our 'software' has to operate on individual level without supervision of a scientist or an engineer. the fact, that it works so well seems miraculous and righteously invokes an idea of an architect to many people … second reason is that bonds forming 'software' in humans is intended to create hierarchy, not egalitarian uniform network. why? because hierarchy is more effective in a small group. good hierarchy means that a group joyfully executes a will of their leader. democracy is only very recent invention and requires individual responsibility … which is still very scarce …

  40. Is this the idiot who came up and said we shouldn't dress up as cowboys and Indians on Halloween because it's not socially acceptable?
    This uber idiocy was spelled out by this SOCIOLOGY professor in Yale.

  42. tremendo importante conocer personalmente el discrimen de odio de personas elitistas con acceso a dinero en Puerto Rico lo hemos sufrido y nuestros hermanos Latinos por los Latinos en negación de Estados Unidos que era Nueva España en 1785 incluyendo partes de Alaska y Canada hoy ups tienen sagre Española . Les dejo Links de inmigraciones por ejemplo la Alemana que comenzo en la Isla antes inclusive que Estados Unidos invadiera en 1898; https://youtu.be/aV26MUJKruo https://youtu.be/kF_Y-5RujDk https://youtu.be/e3KbyuNVVJ0

  43. And this is the professor along with his wife (another professor) that was forced to leave their jobs because they came up with the idea of students policing themselves when it came to choosing halloween costumes.

  44. I wonder what algorithm they used for this.
    There must be some NLP going on here, but how is happy and unhappy measured or obese and not obese? I think he needs to emphasize more on his research methods so we can understand types of errors that he can run into. I'm seeing false positives here.

  45. There is a principal named 'Dependant Origination' denoting that all life is inextricably linked. In essence all life is a microcosm of the macrocosm. In other words we are the universe in miniature. As this reality always exists, how do we 'nourish and sustain' this network, whether obvious to us or not ? The key is inner transformation, sometimes referred to as 'Human Revolution'. In order to become happier we have to raise our life state, or life condition, and in so doing we transform our life and so contribute to the welfare of self and others. As our life and environment are inseparable, the good we do for others comes back to us and the good we do for ourselves benefits others; that way we live without regret. The 64,000 dollar question is how do we raise our life state and what is the most effective way to sustain such a process ? Courage, wisdom and compassion are characteristics innate in all life and likeminded people in the spirit unity to create value with the vision of a sustainable and responsible world are all part of that answer and response to what is so sorely needed in this world today. That includes treasuring the person in our immediate environment and rekindling one's unique qualities and talents to make our respective communities, and beyond, a meaningful place to exist. 'A rising tide raises all ships.'

  46. Thank you Nicholas. I have been given the book "Blueprint" for my birthday, I was interested in the JRE podcast with you and him. It was inspiring I couldn't help but think of A.I. and the importance of 6 degrees of connection. In the psychic medium world if you believe in the afterlife there is "connection".
