The Power of The Rule of Three

Law professors, lawyers, and judges have spent countless hours, whether in law review articles, textbooks, at conferences, or in continuing legal education sessions, providing advice regarding legal writing skills, legal analysis, brief-writing, and persuasive advocacy.

Yet, despite this helpful and practical guidance, law students often struggle to develop effective persuasive writing skills. Law graduates – and seasoned lawyers – frequently face criticism of their writing skills, and judges often lament the less-than-persuasive nature of many pleadings, motions, and briefs. And for good reason. Many trial and appellate briefs, for example, lack a cohesive structure, fail to tell a compelling story, lack precision and concision, violate grammatical rules, contain unnecessary repetition and information, and simply fail to convince the reader to rule in favor of the drafter’s argument.

Having said that, for law students and lawyers who seek to immediately and significantly improve the persuasive value of their briefs, there is one strategy that you should adopt from this day forward: The Rule of Three.

The Rule of Three is simple yet incredibly effective. In the Introduction (or Summary of Argument) section of your brief – and throughout your brief -- identify three specific reasons (and only three reasons) supporting the relief or outcome you seek. And state these reasons with specificity, clarity, and conciseness using First…Second…Third…

Here is an example:

***

Defendant – a well-known tabloid that lacks journalistic integrity – defamed the plaintiff when defendant published an article – to an audience of over one million readers – stating that the plaintiff “was a pathetic attorney who didn’t know the law, preyed on the vulnerabilities of unsuspecting clients, stole their money, engaged in unlawful hiring practices, and repeatedly made inappropriate advances to several clients.”

The defendant’s comments were defamatory for three reasons.  First, the defamatory statements are false. Second, the defamatory statements damaged severely the plaintiff’s reputation and standing in the legal community. Third, the defamatory statements caused the plaintiff to suffer substantial, ongoing, and irreversible, harm.

***

After stating the three reasons supporting the remedy you seek, you should dedicate the next three paragraphs (in the Introduction or Summary of Argument) to relying on the relevant facts or evidence that support each reason. Thus, for example, you should draft one paragraph explaining why the statements were false. Then, you should draft a second paragraph explaining why the statements damaged the plaintiff’s reputation and standing in the legal community. Thereafter, you should draft a paragraph explaining why the plaintiff suffered reputational and economic harm. After that, draft a one-sentence conclusion stating “For these reasons, the defendant’s article was defamatory and thus entitles the plaintiff to damages.” Done.

Also, make sure that your point headings track the three reasons you identify at the outset of your brief. Doing so ensures that your brief will be cohesive, well-organized, and easy to read.

Why is the Rule of Three so effective?

1.    The Rule of Three simplifies your arguments

Judges are very busy. They want to know – quickly – what you want and why you should get it. Briefs that confuse judges or make judges struggle to discern your legal arguments damage your credibility and reduce the persuasive value of your brief.

The Rule of Three avoids this problem. It makes it easy for judges to identify your arguments and evaluate the evidence in support of those arguments. As such, the judge will like you for making his or her job easier. The judge will view you as a credible attorney and give you the benefit of the doubt throughout the litigation. And, ultimately, your client will thank you when you win the case.

2.    The Rule of Three organizes your arguments

The worst briefs are often those that go on…and on…and on…

The worst briefs read like a rambling manifesto that contains a barrage of loosely related thoughts that are jammed into long paragraphs with no separation of the concepts, arguments, or allegations. In short, it is chaos. It is easier to navigate one’s way out of a forest or maze than it is to navigate the arguments that such briefs present.  

The Rule of Three eliminates this problem. It’s quite simple. Say, “First…” and state your argument. Say, “Second…” and state your argument. Say, “Third…” and state your argument. Then, in the next three paragraphs, explain each argument in a separate paragraph – and include each argument as a point heading. Doing so ensures that your arguments will be organized and presented clearly, understandably, and effectively.   

3.    The Rule of Three appeals to the audience’s cognition and psychology

Let’s face it: listening is hard. Paying attention for a prolonged period is difficult. Remembering what we have heard is often challenging. So how do you draft a brief or make an oral argument that will maintain the audience’s attention and convince the audience to adopt your position?

Studies in social and cognitive psychology demonstrate that people respond positively and attentively to arguments that are delivered in sets of three.

The rule of three is ubiquitous. Humans are both neurologically and culturally adapted to the number three and its combination of brevity and rhythm. We know from studies in neuroscience that our brains seek out patterns and finds the structure of three to be a complete set; it feels whole. Three is the least number of items in a series that make a pattern, and once you start looking for this pattern, you’ll see that it’s everywhere.  In mathematics it’s a rule that allows you to solve problems based on proportions. In science there are three states of matter: solid, liquid, and gas. The Latin maxim omne trium perfectum (everything that comes in threes is perfection) echoes Aristotle and his Ars Rhetorica. There Aristotle posits that the most persuasive rhetorical appeals must rely on ethos, pathos, and logos. Extrapolate from that, and even simple storytelling and narratives have a simple structure of a beginning, a middle and an end.[1]

Simply put, the Rule of Three embeds a cohesive structure into your arguments that enhance their readability, appeal, and persuasive value.

Ultimately, the Rule of Three reflects the principle that legal communication (and communication generally) is less complex than you think. It’s about common sense. Use the Rule of Three in your briefs and oral arguments. It’s that simple – and very effective.
