Beyond the Nudge: Reimagining Behavioral Science in an Era of Systemic Scrutiny

By Crystal Hall

“I knew quite well that equal justice was an aspiration. I knew that the force of the law was applied unevenly, sometimes by design. But I also knew that what was wrong with the system didn’t need to be an immutable fact. And I wanted to be part of changing that.”

These words, penned by Vice President Kamala Harris, encapsulate a professional philosophy that has become a lightning rod in the final stretch of the 2024 presidential campaign. As the first woman of color to lead a major U.S. party’s presidential ticket, Harris is no stranger to the intense glare of the public spotlight. However, her current position has invited a new level of scrutiny, one where her career as a prosecutor is being weighed against the broader, often turbulent, dialogue surrounding systemic inequality in America.

For the behavioral science community, Harris’s career trajectory serves as a profound case study. It highlights the tension between working within established, flawed institutions and the imperative to dismantle the structural barriers that produce inequitable outcomes. As the field of applied behavioral science matures, it faces a reckoning: can we continue to focus on individual “nudges,” or must we evolve to address the systemic forces that fundamentally shape the human experience?

The Main Facts: A Career Under the Microscope

Kamala Harris’s entry into the public consciousness as a prosecutor was predicated on a conscious decision to infiltrate a system she recognized as deeply flawed. Her career—from District Attorney of San Francisco to Attorney General of California—has been marked by a balancing act: the exercise of state power within a legal framework that has historically marginalized communities of color.

In the current political climate, opponents have sought to frame her record through a narrow lens of identity politics, aiming to undermine both her credibility and the broader agenda of the Biden-Harris administration. Yet, the substance of her candidacy offers a more complex narrative. Harris represents a departure from the status quo, not merely because of her identity, but because her approach to public policy acknowledges the duality of our institutions: they are inherently imperfect, yet they remain the primary vehicles for systemic reform.

For behavioral scientists, this tension is familiar. We are trained to identify individual decision-making patterns, yet we increasingly realize that those patterns are not merely personal—they are environmental.

A Chronology of Institutional Change

The history of behavioral science is often told through the lens of incremental progress.

• Mid-20th Century: The field emerges, heavily focused on cognitive biases and individual decision-making. The goal is to "correct" individual errors in judgment.
• Early 2000s: The rise of “Nudge” theory (Thaler and Sunstein). Behavioral science moves into the mainstream, with a focus on low-cost, high-impact policy interventions that assume a relatively stable, equitable environment.
• 2020 and Beyond: Following a global reckoning with racial justice, the field begins to face internal criticism. Practitioners begin to ask: What happens when the "environment" is the source of the inequity?
• 2024: The publication of Antiracist by Design: Reimagining Applied Behavioral Science by Mindy Hernandez and myself, marking a formal shift toward integrating systemic analysis into behavioral practice.

This timeline reflects a growing maturity in the discipline. We have moved from observing the individual in a vacuum to acknowledging that individuals are embedded in, and constrained by, systems of power.

Supporting Data: Why Contextual Factors Matter

The traditional behavioral science approach often ignores the "why" behind a choice, focusing instead on how to make the choice easier. But recent research, such as the work of Joel Le Forestier and Neil Lewis, Jr., demonstrates that this is a dangerous omission. Their research into identity concealment patterns reveals that the tendency to hide one’s race, sexuality, or other stigmatized identities is not a character trait—it is a survival mechanism triggered by hostile or unwelcoming environments.

If we look at the data on healthcare access, for instance, we see a clear pattern: “nudges” designed to increase vaccination rates or mental health check-ups often fail in communities that have been historically marginalized by the healthcare system. The failure is not in the individual’s psychology; it is in the systemic lack of trust and the presence of structural barriers.

When behavioral scientists ignore these contextual factors, we risk designing interventions that only serve the privileged—those who are already comfortable interacting with institutional systems. We must shift our metrics from "did they choose the healthy option?" to "did we create an environment where that option was viable, safe, and accessible?"

Official Responses and the Political Discourse

The scrutiny of Vice President Harris’s record is part of a larger, national debate about the role of the state. Critics argue that her past actions as a prosecutor are irreconcilable with the calls for justice she champions today. Supporters argue that her career demonstrates the necessity of "being in the room where it happens" to affect change from within.

From an objective, analytical standpoint, this mirrors the internal debates occurring within social science departments and think tanks across the country. There is a palpable tension between those who believe we should reform systems from the inside—by refining the processes and nudging the decision-makers—and those who believe the systems themselves are fundamentally broken and require total restructuring.

Harris’s approach suggests that these two perspectives are not mutually exclusive. She acknowledges the flaws of the system while remaining committed to using its mechanisms to drive progress. This "balanced view" is exactly what behavioral scientists must adopt if we are to remain relevant in a world that is increasingly aware of structural inequality.

Implications for the Future of Behavioral Science

If we are to evolve, we must move beyond the "nudge." In our forthcoming book, Antiracist by Design, Mindy Hernandez and I propose a roadmap for this transition. The implications for the field are significant:

1. The Systems Analysis Requirement

Before designing any intervention, researchers must perform a rigorous systems analysis. We must stop viewing the individual as an isolated actor and begin to map the surrounding infrastructure. What are the legal, social, and economic forces constraining this person’s choice? If we do not account for these, our interventions will continue to be, at best, ineffective, and at worst, reinforcing of the very systems we seek to change.

2. Participatory Design Methods

We must move away from the "expert-as-designer" model. True, equitable change requires the active participation of the communities we aim to serve. By bringing those with lived experience into the design process, we ensure that our interventions align with actual needs rather than assumptions. This builds the trust that is often missing between marginalized communities and institutional authorities.

3. Redefining Success

We must ask the hard questions: Who benefits from our interventions? Are we reinforcing systems of privilege? Our success should not be measured by the efficacy of a single nudge, but by the extent to which our work contributes to a more equitable society.

Conclusion: A Call to Action

The lesson from Kamala Harris’s career is one of persistence within complexity. It is a reminder that systemic change is not a lightning strike; it is a slow, often frustrating process of navigating flawed institutions with a clear vision of what could be.

For the behavioral science community, the path forward is clear. We have a moral and intellectual obligation to broaden our scope. We must do more than simply influence individual behavior; we must look critically at the systems that shape those choices and work to redesign them with an antiracist, equitable lens.

The inequities in our legal system, our healthcare system, and our economy are not immutable facts. Like any other facet of human society, they are the result of choices made by people within systems. If we are to be true to our mission of improving human welfare, we must be the ones to help change those systems—confronting them head-on, with both the practical tools of our trade and a deep, systemic awareness.

The future of our field depends on our willingness to acknowledge that while individuals make choices, it is the system that defines the menu. It is time to redesign the menu.
