Think Better with Michael Morris

On Wednesday, June 19, 2025, Michael Morris (Columbia University) spoke in Hong Kong for the first-ever international event for the Roman Family Center for Decision Research “Think Better” Speaker Series. Morris discussed fundamental human instincts like the desire to conform and contribute, and how savvy leaders can harness these instincts to drive organizational change.

Morris was introduced by Bernd Wittenbrink, the Robert S. Hamada Professor of Behavioral Science and Wei Cai Faculty in Residence for Spring Quarter 2025. This event was part of the Wei-Cai Faculty in Residence Program and was presented by the Roman Family Center for Decision Research.

Why “Tribal” Isn't What We Think

The idea of tribalism often conjures images of conflict, division, and distrust. But as Morris explains, this popular narrative misses the mark. In his new book, Tribal: How the Cultural Instincts That Divide Us Can Help Bring Us Together, Morris argues that our so-called "tribal instincts" are not inherently hostile. Instead, they are the same instincts that enable humans to form large, complex, and cooperative societies.

Rather than being a source of division, these instincts, rooted in our evolutionary history, can be powerful tools for unity, collaboration, and adaptation. And if leaders understand how these instincts work, they can use them to shape organizational culture and foster meaningful change.

The Three Cultural Instincts That Shape Human Behavior

Morris organizes our evolved tribal psychology into three core instincts:

  • Peer Instinct (Conformity): Humans are wired to fit in. From an early stage in our evolutionary development, we learned to adopt the behaviors and norms of those around us. This instinct helped early humans survive by promoting cooperation and shared knowledge.
  • Hero Instinct (Prestige Learning): Beyond conformity, humans look up to those with status and emulate them. This instinct allows us to quickly learn what’s valued in our group and to aspire to those ideals. It’s why role models are so influential in shaping group behavior.
  • Ancestor Instinct (Tradition): Humans have a unique capacity to preserve and transmit culture across generations. Rituals, ceremonies, and symbols help keep collective memory alive. This instinct enables cumulative cultural evolution—where knowledge builds over time.

These instincts are not outdated. They are active forces in modern life and organizations. Recognizing and activating them through cues, symbols, and rituals can help leaders steer group behavior intentionally.

Cultural Codes and Change: Tribal Triggers

Morris emphasizes that culture is not fixed. People shift between cultural mindsets depending on context. This dynamic nature means culture can be activated—or even transformed—when leaders understand the cues that bring different instincts to the surface:

  • Peer codes respond to signs of tribe and social prevalence. Seeing others do something makes us more likely to follow.
  • Hero codes are triggered by symbols of values and ideals, often embodied in respected figures.
  • Ancestor codes are reinforced by ceremony and tradition, which evoke reverence for the past.

These insights offer powerful tools for managing culture, whether in business, policy, or social movements.

A Case Study: Columbia Business School’s Cultural Reset

Morris shares a compelling example from his own experience helping Columbia Business School shift its organizational culture. At the time, students had little shared identity due to fragmented spaces and unclear symbolism.

Rather than trying to fix this in place, Morris and colleagues planned a cultural reset around a new campus building. The design emphasized openness, community visibility, and shared spaces. They used:

  • Peer signals by ensuring students frequently saw one another
  • Hero signals through design that symbolized innovation and climate responsibility
  • Ancestor signals by hosting ceremonies and traditions on-site

The result: A stronger identity for Columbia Business School, an increase in student cohesion, and a jump in national rankings. This successful transformation showed how thoughtful cultural design, aligned with tribal instincts, can have measurable impact.

Changing vs. Activating Culture

Morris distinguishes between activating existing cultural codes and changing the culture itself. Both are possible, but they require different approaches:

  • To activate culture, use context-specific cues that bring existing norms and values to the forefront.
  • To change culture, use a sequenced strategy. Morris outlines two key models:

The Grassroots Strategy (Bottom-Up):

  • Shift daily practices through visible prevalence (what people see others doing).
  • Elevate new ideals using respected role models through prestige signals.
  • Redefine tradition by connecting change to the past (back-to-the-future messaging).

This strategy is slow but sustainable. Morris cites Kodak’s successful campaign to get Americans to smile in photographs—a cultural shift achieved over decades through this model.

The Shock Therapy Strategy (Top-Down):

  • Disrupt institutions with sweeping reform.
  • Embed new values during the window of change.
  • Shift practices to align with new norms.

This method is faster but riskier. Leaders must have deep legitimacy and understand the culture they are trying to change. When done poorly, it can backfire. But with the right conditions, it can succeed, like Argentina’s economic transformation under President Milei.

Practical Advice for Leaders and Organizations

In the Q&A, Morris offered pragmatic guidance for applying these ideas:

  • Tailor your approach. Identify whether you’re trying to shift norms, ideals, or traditions, and choose the right signals accordingly.
  • Avoid doing everything at once. Cultural overload leads to confusion and resistance.
  • Outsider CEOs beware. Insider leaders often have the cultural fluency to navigate values and avoid backlash.
  • Use legitimacy wisely. Whether invoking tradition or launching reforms, ensure your message feels authentic to your audience.

Morris also emphasizes that culture is not just a barrier; it’s an opportunity. Diverse values, when handled with care, can be a source of creativity and collaboration.

Conclusion

Think Better with Michael Morris was more than an academic lecture. It was a timely exploration of how deep-rooted human psychology can help us build stronger, more inclusive cultures at work, in society, and around the world.

As the Roman Family Center continues to expand its global presence, events like this highlight the Center’s mission: Bridge rigorous behavioral science with real-world impact. In a world often defined by division, Morris reminds us that our tribal instincts, when properly understood, can bring us together.
