The Reptile Theory Explained

The Reptile Theory, sometimes referred to as the "Reptile Brain" strategy, is a trial tactic primarily used by plaintiff's attorneys. It was formally introduced and popularized by David Ball and Don Keenan in their 2009 book. The theory's name alludes to the "reptilian complex," a part of Paul D. MacLean's Triune Brain model, which is theorized to govern primal instincts related to survival and safety.

The Reptile Theory uses the metaphor of the primal "reptilian" brain to describe its focus on safety and survival instincts.

Core Principles and Objectives

At its heart, the Reptile Theory aims to persuade jurors by appealing to their most basic, hardwired instincts for self-preservation and the protection of their community. Here’s how it generally works:

Safety First: The strategy emphasizes framing the defendant's conduct not just as harmful to the individual plaintiff, but as a violation of safety rules that endangers the broader community, including the jurors themselves or their loved ones.
Activating the "Survival Mode": By presenting the defendant's actions as an ongoing threat, the attorney seeks to activate a "survival mode" in jurors. The theory suggests this part of the brain is highly sensitive to danger and will motivate action to neutralize the threat.
Establishing "Safety Rules": Attorneys using this strategy often focus on establishing clear, simple "safety rules" that the defendant allegedly violated. These rules are presented as fundamental standards of conduct necessary for community well-being.
Empowering the Jury: The jury is then positioned as having the power to enforce these safety rules and protect the community by holding the defendant accountable. A significant damages award is often framed as a means to deter future dangerous conduct and ensure public safety.

While the neuroscientific underpinnings of the "reptilian brain" concept as applied in this legal context have been debated by some neuroscientists, the strategy's proponents claim significant success in achieving favorable verdicts and settlements for plaintiffs.

David Ball's Work with the Reptile Theory

David Ball's involvement with the Reptile Theory is foundational. As co-creator, he not only helped conceptualize the strategy but has also been instrumental in its dissemination and refinement through his writings, teachings, and consulting work.

Developing and Disseminating the Strategy

Co-Author and Pioneer

The publication of *Reptile: The 2009 Manual of the Plaintiff's Revolution* marked a turning point. Ball and Keenan provided a detailed roadmap for plaintiff's attorneys, outlining the psychological underpinnings and practical courtroom applications of the theory. This manual became a go-to resource for lawyers seeking to employ this novel approach.

Educator and Consultant

Ball has dedicated a significant portion of his career to teaching attorneys how to effectively implement the Reptile Theory. This involves:

Workshops and Seminars: Conducting training sessions that delve into the nuances of framing case themes, crafting voir dire questions, structuring opening statements and closing arguments, and examining witnesses in a way that aligns with Reptile principles.
University Teaching: His affiliations with various law schools have allowed him to introduce these concepts to law students and practicing attorneys.
Direct Case Consultation: Ball works directly with law firms and attorneys to apply the Reptile Theory to specific cases, helping to tailor strategies to the unique facts and circumstances of each lawsuit.

Emphasis on Ethical and Legal Grounding

A key aspect of Ball's advocacy for the Reptile Theory is his insistence that it should be applied ethically and in alignment with established legal principles. He argues that the strategy is not about manipulating jurors with fear but about highlighting genuine dangers and breaches of societal safety standards that the law is designed to prevent. The focus is on presenting evidence of the defendant's choices that needlessly endangered others, thereby empowering the jury to act as the "conscience of the community."

Understanding the Impact: Reptile Theory in Practice

The chart below offers an analytical perspective on key dimensions of the Reptile Theory as it might be ideally applied by plaintiffs and potentially perceived by jurors. The scores (on a scale of 1 to 10, where 10 is highest impact/emphasis) are illustrative, aiming to represent the theory's intended strengths and areas of focus. This is not based on empirical data but rather on a qualitative interpretation of the theory's principles.

This visualization suggests that a plaintiff ideally applies the Reptile Theory by strongly emphasizing safety framing, community protection, rule violations, and the goal of deterrence, while also aiming for a significant emotional impact and grounding arguments in evidence. The intended juror perception reflects a strong resonance with these themes, leading to an understanding of the danger and a motivation to act.

Understanding David Ball's perspective on trial strategy, particularly concerning juror psychology, is crucial for grasping the nuances of the Reptile Theory. The following video features David Ball discussing how jurors process information and what they look for in a case, offering insights that underpin the Reptile approach.

In discussions like this, Ball often emphasizes the importance of aligning the attorney's presentation with how jurors naturally think and feel. The Reptile Theory is an extension of this philosophy, seeking to connect with fundamental human concerns about safety and well-being. It's about making the case resonate on a level that transcends complex legal arguments, tapping into jurors' inherent desire to protect themselves and their community from harm.

Core Tenets of the Reptile Strategy

The Reptile Theory, as developed by Ball and Keenan, provides a structured approach to plaintiff litigation. Its effectiveness often lies in consistently applying its core principles throughout the legal process. The table below summarizes some of these key tenets and their general application.

Tenet	Description	Example Application in Court
The Primacy of Safety	The central theme is that the defendant violated a safety rule, putting the community (and by extension, the jurors) at risk.	Focusing opening statements on how a company ignored a known safety protocol, leading to widespread danger.
The "Danger" Frame	The defendant's conduct is consistently framed as dangerous, not merely negligent or a mistake.	Using deposition testimony to show the defendant was aware of the risks but chose not to mitigate them, thus creating ongoing danger.
Community Protection	Jurors are empowered as protectors of their community, and their verdict is a tool to ensure safety.	Arguing in closing that a verdict for the plaintiff sends a message that such dangerous behavior will not be tolerated in the community.
Violation of Basic "Safety Rules"	The case revolves around simple, undeniable safety rules (e.g., "A driver must not text while driving," "A doctor must ensure patient safety").	Presenting expert testimony that clearly defines the relevant safety rule and how the defendant's actions broke it.
The Bigger Picture	The harm to the plaintiff is presented as an example of what can happen when safety rules are broken, implying a broader threat.	Questioning witnesses about the potential for similar harm to others if the defendant's conduct is not addressed.
Damages as Deterrence	Monetary damages are sought not only for compensation but also as a means to punish past conduct and deter future wrongdoing, thereby protecting the community.	Explaining how a substantial damages award is necessary to make the defendant change its dangerous practices and prevent future harm.

This structured approach aims to create a compelling narrative that resonates with jurors' fundamental concerns for safety and justice, leading them to view the case through the lens of community protection.
