Have you ever wondered what makes humans unique? One fascinating aspect is our deep concern with morality. As social beings, we constantly seek to understand the motivations behind people’s actions. My own curiosity about morality was inspired by my mother, Sister Mary Stella, and my experiences as an altar boy. Surrounded by incense and Latin phrases, I often pondered whether moral principles were universally applicable. This curiosity led me to explore the chemistry behind moral decisions, specifically searching for a “moral molecule.”
After a decade of research, I believe I have identified this molecule: oxytocin. This simple and ancient molecule is found only in mammals. In rodents, it encourages maternal care and fosters tolerance among burrow mates. In humans, oxytocin is known for its role in childbirth, breastfeeding, and intimate moments.
Initially, my hypothesis that oxytocin might be the moral molecule was met with skepticism. Some colleagues dismissed it as a “female molecule” with limited significance. However, I argued that since men also produce oxytocin, it must play an important role in human behavior.
To test whether oxytocin influences moral behavior, I needed to measure it accurately. This was challenging due to its low baseline levels and short half-life. However, since oxytocin is produced in both the brain and blood, I could conduct experiments without invasive procedures.
I focused on trustworthiness as a key virtue. In the early 2000s, I found that countries with more trustworthy individuals tend to be more prosperous. To explore this further, I designed an experiment where participants were given ten dollars and could choose to share it with another person. The amount shared would be tripled for the recipient. Surprisingly, 90% of participants sent money, and 95% of recipients returned some of it.
By measuring oxytocin levels, we discovered that the more money the second person received, the more oxytocin was produced, and the more they returned. This suggested a biological basis for trustworthiness. To establish a direct causal relationship, we conducted an experiment using a nasal inhaler to manipulate oxytocin levels. Participants who received oxytocin showed increased trust, with more sending all their money to a stranger.
Further studies revealed that oxytocin infusion increased generosity in monetary transfers and donations to charity. We also explored non-pharmacological ways to raise oxytocin, such as massage, dancing, and praying.
To understand the emotional impact of oxytocin, we conducted an experiment where participants watched a video of a father and his terminally ill son. Changes in oxytocin levels predicted their feelings of empathy, suggesting that empathy connects us to others and drives moral behavior. This aligns with Adam Smith’s philosophy that we are moral creatures because we share the emotions of others.
Understanding the molecule behind morality helps us identify what influences moral behavior and what can inhibit it. Some individuals do not release oxytocin in response to trust, leading to selfish behavior. High stress and improper nurturing can also inhibit oxytocin release. Interestingly, testosterone can affect this system, as higher levels can lead to selfish behavior but may also motivate individuals to punish others for immoral actions.
To see if these findings apply in real life, I attended a wedding in Southern England and took blood samples before and after the vows. The results showed that weddings cause a significant release of oxytocin, particularly in the bride and her mother. I also explored the role of social media in increasing oxytocin levels and found that interactions on social media can lead to substantial spikes in oxytocin.
In conclusion, oxytocin connects us to others and enhances our feelings of empathy. Simple actions, such as hugging, can increase oxytocin levels and improve our relationships. So, embrace the idea of “eight hugs a day” for a happier life. Thank you!
Engage in a virtual simulation where you can manipulate oxytocin levels in a controlled environment. Observe how changes in oxytocin affect trust and generosity in various scenarios. Reflect on how these findings relate to real-world social interactions.
Participate in a structured debate on whether oxytocin should be considered the “moral molecule.” Prepare arguments for and against this hypothesis, drawing on evidence from the article and additional research. This will enhance your critical thinking and public speaking skills.
Analyze a series of case studies that illustrate the role of oxytocin in moral decision-making. Discuss in groups how oxytocin might influence outcomes in each case, and propose alternative scenarios based on different oxytocin levels.
Attend a workshop focused on empathy-building exercises. Learn about the connection between empathy and oxytocin, and practice techniques such as active listening and perspective-taking to enhance your empathetic responses.
Develop a research proposal to explore a new aspect of oxytocin’s role in human behavior. Identify a specific hypothesis, design an experiment, and outline the methods you would use to test your hypothesis. This activity will help you apply scientific research principles.

Is there anything unique about human beings? Yes, we are the only creatures with fully developed moral sentiments. We are obsessed with morality as social creatures; we need to understand why people do what they do. Personally, I am fascinated by morality, and this interest stems from my mother, Sister Mary Stella.
As an altar boy, I was surrounded by incense and learned to say phrases in Latin, but I also had time to ponder whether my mother’s top-down morality applied universally. I observed that both religious and non-religious people were equally concerned with morality. This led me to wonder if there was an earthly basis for moral decisions, and I wanted to explore the chemistry of morality. Specifically, I sought to identify a “moral molecule.”
After ten years of experiments, I believe I found it. Would you like to see it? I brought some with me. This syringe contains the moral molecule known as oxytocin.
Oxytocin is a simple and ancient molecule found only in mammals. In rodents, it is known to encourage maternal care for offspring and, in some species, foster tolerance among burrow mates. In humans, it was primarily recognized for its role in childbirth and breastfeeding, as well as being released during intimate moments.
I hypothesized that oxytocin might be the moral molecule. I shared this idea with colleagues, but one of them dismissed it as the “world’s stupidest idea,” claiming it was only a “female molecule” and couldn’t be that significant. However, I countered that men also produce oxytocin, suggesting there must be a reason for its importance.
Despite the skepticism, I believed I could design an experiment to test whether oxytocin influences moral behavior. However, I soon discovered that measuring oxytocin was challenging. Its baseline levels are low without a stimulus, and it has a short half-life, degrading quickly at room temperature. Thus, I needed to create a surge of oxytocin and capture it rapidly.
Fortunately, oxytocin is produced in both the brain and blood, allowing me to conduct my experiment without needing neurosurgery. I decided to focus on one specific virtue: trustworthiness. In the early 2000s, I had shown that countries with a higher proportion of trustworthy individuals tend to be more prosperous, as more economic transactions occur, alleviating poverty.
To investigate the chemistry of trustworthiness, I designed an experiment where participants were tempted to share money. They would receive ten dollars and could choose to give some to another participant they couldn’t see or talk to. The amount they gave would be tripled for the other person. Surprisingly, we found that 90% of the first decision-makers sent money, and 95% of those who received money returned some.
By measuring oxytocin levels, we discovered that the more money the second person received, the more oxytocin was produced, and the more they returned. This indicated a biological basis for trustworthiness. However, I still needed to establish a direct causal relationship between oxytocin and trustworthiness.
To do this, I used a nasal inhaler to manipulate oxytocin levels directly. In collaboration with colleagues in Zurich, we conducted an experiment with 200 men, administering oxytocin or a placebo. Those who received oxytocin showed increased trust, with more participants sending all their money to a stranger.
Further studies revealed that oxytocin infusion increased generosity in monetary transfers and donations to charity. We also explored non-pharmacological ways to raise oxytocin, such as massage, dancing, and praying.
To understand the emotional impact of oxytocin, we conducted an experiment where participants watched a video of a father and his terminally ill son. The change in oxytocin levels predicted their feelings of empathy, suggesting that empathy is what connects us to others and drives moral behavior.
This idea aligns with the philosophy of Adam Smith, who argued in his 1759 book, “The Theory of Moral Sentiments,” that we are moral creatures not because of top-down reasoning but because we share the emotions of others.
Understanding the molecule behind morality is valuable because it helps us understand what influences moral behavior and what can inhibit it. For instance, we found that some individuals do not release oxytocin in response to trust, which can lead to selfish behavior.
Additionally, high stress and improper nurturing can inhibit oxytocin release. Interestingly, testosterone can also affect this system, as higher levels can lead to selfish behavior, but they may also motivate individuals to punish others for immoral actions.
To see if these laboratory findings apply to real life, I attended a wedding in Southern England, where I took blood samples before and after the vows. The results showed that weddings cause a significant release of oxytocin, particularly in the bride and her mother.
I also explored the role of social media in increasing oxytocin levels and found that interactions on social media can lead to substantial spikes in oxytocin.
In conclusion, oxytocin connects us to others and enhances our feelings of empathy. Simple actions, such as hugging, can increase oxytocin levels and improve our relationships. So, I encourage you to embrace the idea of “eight hugs a day” for a happier life.
Thank you! [Applause] [Music]
