In this special live episode of Passion Struck, John R. Miles joins psychologist Rick Hanson and Harvard’s Joshua Greene to unpack us vs them psychology, why our brains are hardwired for tribal division in a connected world, and how neuroscience offers a path to broader belonging and compassion.
At a time of rising polarization, this conversation reveals the evolutionary roots of outrage and exclusion and practical ways to expand your moral circle without erasing differences. Framed around the Pods Fight Poverty initiative, it turns insight into real impact for families in extreme poverty.
Together, they explore how moral psychology and neuroscience explain why tribal thinking feels so automatic, why belonging and mattering are biological needs, and how we can expand the moral circle without denying fundamental differences.
Why the Human Brain Is Wired for Us vs Them Psychology
Joshua Greene explains that us vs them psychology evolved for tribal survival: internal cooperation, external vigilance. Today, it amplifies polarization as disagreement feels like an existential threat.
Human moral systems developed to help small groups cooperate internally while competing externally, allowing early societies to survive in harsh environments. Morality, in this sense, evolved as a coordination tool. It helped people trust those inside the group and remain vigilant toward those outside it.
The challenge today is that these ancient instincts are now operating in a hyperconnected world. The brain still reacts as if disagreement signals danger, even when the threat is ideological rather than physical. What once protected us now fuels polarization, outrage, and moral certainty. Recognizing this wiring does not excuse harmful behavior, but it gives us the awareness needed to interrupt it.
Moral Psychology, Tribalism, and the Roots of Polarization
Moral psychology reveals why division feels so emotionally charged. Greene describes how beliefs about right and wrong become tightly bound to identity, turning disagreement into a personal threat. When people feel their moral values are under attack, they do not simply defend ideas; they defend who they are.
This is why facts alone rarely soften polarization. When moral identity is activated, the nervous system shifts into a defensive state. Outrage becomes reinforcing, and tribalism hardens. The episode makes clear that overcoming polarization is not about winning arguments. It is about restoring the psychological conditions where openness becomes possible again.
Rick Hanson on the Neuroscience of Belonging and Threat
Rick Hanson grounds the conversation in neuroscience, explaining how the brain constantly scans for signals of safety or exclusion. When people feel they belong, threat systems in the brain quiet down. When they feel dismissed, judged, or dehumanized, those same systems activate rapidly, often before conscious thought.
Belonging, Hanson emphasizes, is not an abstract ideal. It is a biological need tied directly to resilience, emotional regulation, and cooperation. This is why cultures that foster inclusion tend to produce greater trust and stability. When people feel that they matter, the brain becomes more capable of compassion rather than defense.

- Pods Fight Poverty: Turning empathy into life-changing cash transfers
Why This Matters Today
In echo chambers and stressed times, us vs them psychology erodes trust. Understanding it empowers pause, response, and inclusion.
Expanding the moral circle is not theoretical. It shapes how we lead, how we raise children, how we handle disagreement, and how we decide who belongs. This episode reminds us that even in a fractured world, we retain the capacity to choose compassion, cultivate belonging, and act in ways that help others feel that they matter.
Expanding the Moral Circle Without Denying Difference
Expanding the moral circle does not mean erasing disagreement or pretending differences do not matter. Greene emphasizes that moral change happens incrementally. People must be met where they are, not pushed into positions they experience as threatening.
Curiosity plays a critical role here. When curiosity replaces certainty, fear loosens its grip. Hanson adds that compassion can be deliberately cultivated by recognizing shared humanity, regulating emotional reactivity, and choosing care even when it feels difficult. Over time, these practices widen the circle of concern and make cooperation more likely.
Compassion as Strength and Moral Courage in Practice
One of the most powerful reframes in this episode is the idea that compassion is not weakness. Hanson explains that compassion combines empathy, care, and the motivation to help. While empathy alone can be exhausting, compassion is protective because it includes warmth and agency.
This distinction matters in a world facing compassion fatigue. Moral courage, as discussed here, is the ability to stay human under pressure. It is holding boundaries without dehumanizing others and choosing responses that align with values rather than impulses. Compassion, when practiced this way, becomes a source of strength rather than a source of depletion.
Teaching Belonging and Moral Courage to the Next Generation
The conversation turns toward children and adolescents, where the pull of tribal belonging is powerful. Hanson and John R. Miles discuss how young people often self-censor to avoid rejection. This pressure can erode self-worth and moral agency early in life.
The episode highlights that teaching compassion is not only about individual skills like mindfulness or empathy. It also requires transforming the systems children move through, including schools, families, and digital spaces. When belonging becomes conditional, moral courage shrinks. When environments support dignity and inclusion, it grows.
Pods Fight Poverty as Expanding the Moral Circle in Action
This live Passion Struck episode was created in support of Pods Fight Poverty, an initiative that turns the ideas discussed in this conversation into real-world impact. As Joshua Greene explains, expanding the moral circle is not just about caring more. It is about choosing actions that reliably make a difference.
Together with GiveDirectly and Giving Multiplier, podcasters are working to send unconditional cash transfers to every family across three villages in the Bikara region of Rwanda, reaching more than seven hundred households living in extreme poverty.
Each family will receive approximately $1,100 through secure digital transfers, allowing them to decide how best to meet their needs and invest in their futures. While matching funds last, donations through Passion Struck are doubled, meaning every contribution goes twice as far.
For families in Bikara, who often live on $1–$2 a day, this support represents more than a year’s income. Most rely on small-scale farming, lack sufficient land to grow enough food, face unreliable access to clean water, and lack capital for education or small businesses. Direct cash restores dignity and agency by trusting people to choose what matters most.
Research shows that this approach works. Cash transfers improve food security, reduce infant mortality, and stimulate local economies, creating ripple effects that extend beyond individual households. Stories like Winfred’s, who was able to clear debt, support her children’s education, invest in livestock, and improve her living conditions, illustrate how choice becomes transformation.
Pods Fight Poverty embodies the heart of this episode. Expanding the moral circle means moving from a us-versus-them mindset to acting in ways that restore dignity and opportunity. In a world where much feels out of our control, this is one place where individual action truly scales.

An Invitation to Act
This conversation reminds us that us vs them psychology is not a personal failing but a deeply human inheritance. Yet as Rick Hanson and Joshua Greene make clear, understanding our wiring gives us power. Power to pause instead of react. Power to choose compassion without abandoning discernment. Power to expand the moral circle so that more people feel seen, valued, and that they truly matter.
John R. Miles closes this live episode by grounding the science in responsibility. If belonging is biological and moral courage is learnable, then rebuilding trust is not someone else’s job. It begins with how we show up in our relationships, our communities, and the systems we support. Pods Fight Poverty offers one concrete way to turn insight into impact, translating shared humanity into dignity, agency, and opportunity for families who need it most.
In a world where division is loud and exhausting, this episode is an invitation to something quieter and more powerful. To remember our shared humanity. To act with intention. And to choose all of us over us versus them.
