Having a laugh with someone whilst standing in a queue, whose name you don't even know, or see the exhilarated look of surprise and appreciation on a stranger's face when you go out of your way to help them with something, is a great feeling. It is like a drug effect.

I hug my dog 8 times a day. I love my poochie and my poochie loves me. I'm glad that she can make oxytocin too. Life is good.

Mr Zac, that was incredibly interesting and makes so much sense of things that I've wondered about! I saw something on telly (a few years ago-English) where they measured the levels of oxytocin produced during a wedding, and I'm rather guessing that was the wedding you were talking about.

This is so fascinating!! Back when TED used to be amazing to watch.

Thank You

Massage, Dancing and Praying- Yes!

YES> Love this guy and his work. Met him yesterday. A kind and connected soul... Hugs are the future... RVE

I'm so glad they lowered the intro volume!

8:13 - a words to live by

Great speaker. This is one of those 1 in 50 ted talks that I'll really remember

i have his book and i find his ideas very interesting and logical ,i dont know why people judge him wrong.

That was amazing!!! One of the best TED talks ever!

This reminds me of the "Ron Gutman: The hidden power of smiling" and the "Amy Cuddy: Your body language shapes who you are" TED Talks...interesting!

Excellent! This is a real breakthrough! I wonder what effect music has on this...

Paul Zak , I just sent this to everybody I love and to the World. About Prayer, That was so cool. 307,950 views •

John Oliver had some things to say about this talk

@delatroy You miss the point completely. He's argument was that the capacity to produce oxytocin is a human faculty, but that the faculty can be inhibited by various factors (chemical, psychological, etc.). His aim is not to paint it as being a niche-specific factor in contributing to empathy and trust, but as a prima facie heuristic for gauging empathic social interaction.

Thank you! This eviscerates anything sacred or pure about a notion of higher truth. I don't disagree with research (in fact, I myself am part of oxytocin research and aging) but I at least someone recognizes the gravity of this

Woow!! I came here from Método CIS by Paulo Vieira from Febracis. Amazing how great is to produce confidence through people to build a better world. OGA! (The Giant Awake - O Gigante Acordou!)

Brilliant--engaging--powerful!

reminds me why i subscribed to TED, love it :)

@Mgopro omg they did. I didn't notice because I'm so used to skipping past it. FINALLY

@1:30 "Breathe it in!!! Breathe ittttt!"

Excellent presentation!

I've actually been very interested in morality as of late because it came up in a debate with a very nice Christian, and I was unable to explain morality at that time. Now I have an answer for both myself and others regarding the reason we are moral, as well as a new line of research to follow!

thank you great video

I love this video. Everything just makes sense. It is so true that when you are feeling ramped up on testosterone, your emotional connection with others is down. I find it interesting that testosterone and oxytocin are opposite (in effect) to each other.

Thank you science!

It works I heard about hugging your kids to reduce stress years ago and something so little makes a big difference

good researcher and a good showman !

I want a hug :( I want more oxytocin!

Love this

This is the first talk where the Ted gingle didn't try to make me deaf! I love it!

@Bracerjack reading your comment spiked mine, I believe...empathy is powerful...

I thoroughly enjoyed this! What a great guy =) Need more research from him!

I learned a lot from this. Thank you!

This made me wanna hug somebody right now : )

Just watching the hug increased my oxytoxin, I could feel it

i like this alot...this made me happy

Thank you ! :)

brilliant thanks

I love it when I understand what the top comments actually are saying when I've seen the whole Ted Talk.

Very interesting and informative.

So good.

very nice talk.

Touching research.

Amazing!

I've loved it!

I really love his voice... O_O

обожаю обнимашки!!)) видимо мой окситоцин на высоком уровне)) есть ощущение, что людям при взаимодействии со мной становится лучше им не хочется от меня уходить 😊 хоть пожилые хоть совсем маленькие детки 🥰

this guy is too good

Interesting talk about molecular interactions forming societal changes

I loved this talk! It's a little hard to swallow though; I always regarded morality as a social convention that varies in each culture. Maybe oxytocin would be more related to empathy, from which morality stems?

Incredible !

@mellamosean Exactly, the thing is what psychologists bring is not a conflicting answer to what Paul Zak brings.

Wonderful speech! I am watching it over and over again... Maybe it's my oxytocin. :-)

Very intresting talk 👍👍

I love it!

Fantastic! A must see :)))

I always heard that hugging it out 8 times a day would make you go blind.

love this :)

@aadrian13 It basically helps us cooperate so we can survive. If a person's oxytocin system is well-developed, they'll be more likely to be caring and giving individuals. By the experiments in this video, it looks like it makes a fairly significant difference in a person's generosity level. I agree, it will definitely not inhibit our reason of why someone values generosity, but I think instead, it will make someone value it through the rewards and feelings of giving.

Me and my friend Aldous Huxley approve !!! Please create this drug for wide use as soon as possible

Makes me feel sane that others think this way:)

An excellent talk. All we need now is to find the Higgs Boson :)

I would be interested in oxytocin levels under the influence of different drugs, particularly comparing alcohol and pot, but also coffee, sugar, nicotine. Also what about different jobs, habits, etc. It would be really interesting to see if there is any connection between drinking coffee before work, or listening to a specific genre of music, stuff like this, and the economic state of a country.

Wonderfull

Reducing morality to cooperation, survival or feeding some internal reward system can only explain some very basic human behaviour, but not our notions of what is right and wrong.

So cool.

Uaooo FANTRASTIC, THANK YOUUU Dr. PAUL ZAK.

@Anthrax1551 I agree. I don't think it would be enough data to base conclusions on on its own but combined with other measurements it would surely give us some great insights!

John Oliver makes some great points about science - I’d highly recommend that video to everyone! (Search “John Oliver science” - it’s about 20 minutes long. The four minute one is not impressive when compared to the whole thing.) I also want to throw out some resources for people watching this who are interested in learning more about this particular research or oxytocin in general. One main point was brought up by John Oliver - oxytocin doesn’t necessarily make you happier all the time, but it does seem to be involved with the ability for social adaptation by normalizing under- or over-active functioning Ma, Shamay-Tsoory, Han, & Zink, 2016). That might sound a little vague and dry, but it provides the foundational knowledge for a whole lot of research that goes beyond morality. A lot of the research looks at social perception or social cognition. One interesting study reports that in a game of chance with a confederate, oxytocin appears to increase envy and gloating when participants won less and more, respectively, than the confederate (Shamay-Tsoory et al., 2009). Perhaps, that counts as being involved with morality. For a more comprehensive picture, I’ll outline a few possible situations that I considered and try to reason through some perspectives on oxytocin research. Any error or misinterpretation that follows is mine alone. When I was reading some literature on oxytocin for a class last term, I tended to think about 3 possible interpretations of this talk. If it was not already clear, these possibilities are more conjecture than systematic literature review. Anyone who is interested in this topic is encouraged to conduct their own literature review, but I have included references to some sources. 1) Paul Zak’s findings have been appropriately interpreted in the literature. Question: What did Dr. Zak find? Answer: It’s complicated; see “Option 1” below. 2) Paul Zak’s findings have been misinterpreted in the literature (as they were in this video). Question: Has the research begun to correct itself? Answer: Outlook is good; see Ma et al. (2016); Leng & Ludwig (2016). 3) Paul Zak’s findings are the result of questionable research practices and intranasal oxytocin does not increase trust. Question: Is there evidence for this? Answer: Uncertain; for one perspective, see Conlisk (2011). Option 1 What did Dr. Zak find? Below is a quote from Kosfeld, Heinrichs, Zak, Fischbacher, & Fehr (2005): “Our hypothesis that oxytocin increases the trusting behaviour of investors implies that the investors in the oxytocin group (n = 29) will show higher money transfers than those in the placebo group (n = 29). In fact, our data show that oxytocin increases investors’ trust considerably. Out of the 29 subjects, 13 (45%) in the oxytocin group showed the maximal trust level, whereas only 6 of the 29 subjects (21%) in the placebo group showed maximal trust (Fig. 2a). In contrast, only 21% of the subjects in the oxytocin group had a trust level below 8 monetary units (MU), but 45% of the subjects in the control group showed such low levels of trust. These differences in the distribution of trust result in higher average and median trust levels for subjects given oxytocin (Table 1). The investors’ average transfer is 17% higher in the oxytocin group (Mann-Whitney U-test; z = -1.897, p = 0.029, one-sided), and the median transfer in the oxytocin group is 10 MU, compared to a median of only 8 MU for subjects in the placebo group.” (p. 674) What does that mean? One finding seems very interesting - if you look at the figure (not included), there’s one very important bar - the “percentage of people showing maximum trust”. It’s a lot higher for the oxytocin category. Does this reflect trust per se, or a social adaptive process of weighing financial risks and gains? The researchers interpret the phenomenon as an increase in trust because the oxytocin only seems to work when the participant invests with a person, compared to a game played with a computer. I don’t know if I’d think “if I give all my money to this computer, its randomization procedures might spit out more money” in the computer game. While the researchers may have controlled for details like this, I’d be inclined to factor in social considerations when giving my money to a person who may or may not provide a return on the investment. Do we think that this is trust? I didn’t do much research into trust, and I won’t claim to be an expert on trust or morality. I think looking at how oxytocin is involved in many different situations helps to understand a larger, more nuanced picture of the role of oxytocin. A personal summary (no citations). Oxytocin seems to increase desire for investment returns, and specifically investment behavior when there is financial risk involved with investing money through a human banker.

this is how equilibrium starts

Empathy―the ability to feel what another person is feeling―is a very important human characteristic.This is because it encourages us to treat other people with kindness.But why do some people feel more empathy than others? Scientists believe that the answer may lie in a chemical called oxytocin.This chemical is related into the blood when women are pregnant,leading them naturally to form strong bonds with their babies

omg this explains SO much... especially why women tend to be more emphatic. Wow.

On a spur of the moment thought , it may be interesting to take an underlying look at some of the research being done at the institute of Heartmath like the youtube video example "Heartmath I am" and cross reference it to research on this subject the two subjects may cross relate.

Thanks for introducing the trust molecule, oxytocin.

@mobubabe You can click on the time to skip the loud intro. It is really just for everyone's convenience.

4 years ago, i got awarded "most friendliest" in high school and i said "just follow the 8 hugs a day rule". i should get credit for this... lol

we have a biology of trustworthiness. fascinating stuff.

Yes, it's mostly utilitarian, but i've arrived at it through analysis and reflection, and actually use it in practice. I also do some charitable work because i can, by donating some of my computers idle processing power to science (Folding@Home) and some money to other causes (currently SOS Children's Villages). I don't advertise this, but confronted with your comment it gives context. I'm quite cynical and emotionally reserved, but if you ask people who know me i'm a "nice and helpful guy".

wow this is fantstic!

Interesting. I relate a lot to empathy and sharing. Have been doing both very easily since childhood. I don't think twice about giving something away, even if I could still use it. But the hugging part is tough. It is very uncomfortable. I stiffen up and only do it because I have to. So is it better to just skip that action or force it until I get used to it?

Lots of hugs¬¬¬¬¬!Q!!!!!

this is very likable, it's also crazy

@joeloud1 He's a neuroeconomist, not an economist. From wikipedia: It combines research methods from neuroscience, experimental and behavioral economics, and cognitive and social psychology.

@aadrian13 Actually it explains the current physical reason for generosity in high regard, i.e. the "moral molecule" being released. However, from a slightly more complicated thought it does not explain for what reason this is started ocurring etc. I think that will come from evolutionary biology, but currently we work with what we've got.

Paul Zak needs Tony Robbins to teach him how to catch the crowd's attention using EMOTION. Great topic, monotone lecture.

Regarding this, someone said to me: "Morality based on empathy seems to be the only testable moral system, where causes and effects are not abstract, but objectively measurable in the brain." But this is unjustifiable presumption. The first presumption is that you can't test abstract things. The second presumption is that you should be able to test morality. The third presumption is that neuron firings don't under- or over-determine one's mental world, but are like a ticker-tape for stock prices

He said his nickname was "Dr. Love" I'm going to use that for my R&B name.

Interesting... I need a hug.

Interesting

@TheChrisMedico you should watch serenity ( the movie )

I'm just here for the ASMR value.

6:34 max headroom lol

cool!

@mellamosean cool. i do wonder about sample of the experiment.

Arh! Free hug. So this is where the idea of "safe space" come from.

@aadrian13 it seems like the decision to make "the right moral" choice may come from previous experiences i.e. brain chemistry/neural pathways reinforced by the reward from a previous 'analogous' interaction. Moral dilemmas may arise from the fact that there is no strong oxytocin induced neural pathways and no way to establish it because of its subjective nature and maybe that's why makes us think harder.
