“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, serve as a poignant reflection on her decision to enter the legal profession—a career path defined by the tension between upholding the law and grappling with its inherent inequities. As Harris navigates the final, high-stakes stretch of the 2024 presidential campaign, these reflections have become a focal point of public discourse. Her professional history as a prosecutor and Attorney General, once seen as a traditional ladder to the Vice Presidency, is now under a microscope, subjected to the intense scrutiny of a polarized electorate.
However, beyond the political theater lies a profound question for the social sciences: How do we reconcile individual agency with the massive, often rigid, structural forces that define our society? For the field of behavioral science, Harris’s career offers a compelling case study. It forces us to move past the traditional, narrow focus on individual decision-making and confront the reality that systemic forces—such as institutional racism—are not merely "background noise." They are the primary architects of the choices available to citizens.
The Architecture of Choice: A New Framework for Behavioral Science
Historically, applied behavioral science and behavioral economics have been characterized by the “nudge”—a philosophy popularized by thinkers like Richard Thaler and Cass Sunstein. The premise is elegant: by subtly changing the environment in which choices are presented (the “choice architecture”), we can steer individuals toward healthier, more sustainable, or more socially beneficial outcomes.
While this approach has achieved significant successes, it is increasingly clear that the “nudge” paradigm often operates under a dangerous assumption: that the individual exists in a vacuum. It assumes that if we tweak the presentation of a retirement plan or a tax form, the user’s cognitive biases will be mitigated, and a “better” choice will follow.
But what happens when the choice itself is constrained by systemic inequity? If a person faces a biased justice system, a discriminatory housing market, or a healthcare system riddled with racial disparities, a subtle nudge toward “better decision-making” is, at best, insufficient and, at worst, an exercise in victim-blaming.
Chronology of a Shifting Paradigm
The evolution of behavioral science can be viewed through several distinct phases:
- The Era of Individualism (1970s–2000s): The field emerged from cognitive psychology, focusing on heuristics and biases. The goal was to identify why humans are "irrational" actors.
- The Nudge Revolution (2008–2015): Behavioral science moved into the policy sphere. Government agencies, including the White House Social and Behavioral Sciences Team, began applying these insights to public administration.
- The Critical Realignment (2016–Present): A growing body of researchers, including my colleague Mindy Hernandez and myself, began to argue that the “individualist” approach was failing to address the root causes of social disparity.
This chronology mirrors the broader cultural shift in American politics. Just as Vice President Harris’s career has moved from a traditional “law and order” framework to one that increasingly acknowledges the need for systemic reform, the field of behavioral science is undergoing a similar maturation. We are moving from asking, "How can we change this person’s choice?" to "How can we redesign this system to be inherently equitable?"
Supporting Data: Why Context Matters
The necessity of this shift is supported by mounting empirical evidence. A landmark paper by Joel Le Forestier and Neil Lewis, Jr., provides critical insight into the relationship between identity and environment. Their research demonstrates that the concealment of stigmatized identities—whether related to race, sexuality, or socio-economic status—is not a static individual trait. Rather, it is a dynamic response to the context.
When an individual operates within a hostile or unwelcoming system, the cognitive load required to navigate that system increases exponentially. This is not a "cognitive bias" that can be corrected by a better website design or a simpler form. It is a rational, adaptive response to a structural threat.
If behavioral scientists ignore these contextual factors, they risk designing interventions that only serve the privileged—those who are already secure within the system. For instance, interventions designed to improve mental health outcomes often fail to account for the deep-seated distrust of healthcare institutions among marginalized communities. By ignoring the historical and structural reasons for that mistrust, we design interventions that are effectively blind to the very populations that need them most.
Official Responses and the Political Crucible
The scrutiny surrounding Vice President Harris is emblematic of a national debate regarding institutional change. Critics often demand purity, arguing that one cannot fix a broken system from within. Proponents, however, point to the incremental but vital progress made by those who engage with the machinery of government.
This mirrors the debate within the behavioral science community. Are we “complicit” if we work with government institutions that have historically reinforced inequality? Or is it our professional obligation to bring our tools inside those institutions to force a change from within?
In my forthcoming book, Antiracist by Design: Reimagining Applied Behavioral Science, I argue for the latter, but with a critical caveat: we must abandon the delusion of neutrality. There is no “neutral” system. Every policy, every nudge, and every intervention has a design bias. If that design does not intentionally account for systemic racism, it is, by default, reinforcing the status quo.
Implications for Future Research and Policy
The implications for our field are profound. To evolve, behavioral science must adopt three core pillars:
1. The Systems Analysis Requirement
Before designing any intervention, researchers must perform a rigorous systems analysis. This involves mapping the constraints that surround the target population. What are the legal, economic, and social barriers that make the "desired" choice difficult or impossible? By identifying these constraints, we move from being "nudge" designers to being "system" architects.
2. Participatory Design Methods
We can no longer conduct research on communities; we must conduct research with them. Participatory methods ensure that those who are most affected by systemic inequities have a seat at the design table. This does more than improve the efficacy of an intervention; it builds the trust that is currently missing between institutions and the public.
3. Acknowledging the "Immutable"
Vice President Harris’s acknowledgment that the justice system is flawed is a model for our own professional humility. We must stop pretending that our field can “solve” deep-rooted social problems through clever messaging or minor behavioral adjustments. We must be willing to advocate for policy changes that exist outside of the behavioral domain—such as zoning reform, sentencing reform, and the dismantling of discriminatory institutional policies.
A Call to Action
The challenge for the next generation of behavioral scientists is to broaden the scope of our ambition. We must ask ourselves: Who benefits from our interventions, and who is being left behind? Are we designing for the "average" human, or are we designing for the most vulnerable among us?
The career of Kamala Harris serves as a powerful metaphor for the work ahead. It reminds us that systemic change is not a binary choice between "doing nothing" and "destroying everything." It is a long, arduous process of working within the system while relentlessly exposing its flaws and redesigning its components for equity.
As we look toward the future, the behavioral science community stands at a crossroads. We can continue to refine our nudges, or we can take the more difficult path: the path of antiracist design. The former will keep us relevant in the short term; the latter is necessary to ensure our work has a meaningful, lasting impact on the world.
If we truly want to influence behavior, we must first be willing to change the systems that dictate the possibilities of human life. The time for individualistic, narrow-scope behavioral science has passed. The era of systemic, intentional, and equitable design has arrived. It is not just an opportunity for our field; it is a moral imperative.
