Brunson's first rule of captivating storytelling: oversimplify — speak at about a third-grade level.1
Many experts resist this because they like using big words to sound smart. Brunson says that's exactly backwards: the big words lose people, and losing people loses sales.
People digest information at a third-grade level, and going above it starts shedding your audience.2
There's a reason news anchors speak at this level. It's not that the audience is stupid — it's that simple language is what actually gets received, and reception is the whole point.
The mechanism: comprehension is a bottleneck, and every increment of complexity narrows it.3
When you use a word or concept the listener doesn't immediately grasp, they stop — and Brunson notes that once they hit something they don't understand, they stop paying attention to everything after it too. One unfamiliar term doesn't just lose that point; it loses the rest of the message.4
So complexity doesn't make you seem smart to your audience — it makes you inaudible to them past the point of confusion. Simplicity isn't dumbing down the content; it's keeping the channel open so the content can arrive at all.
This is why the instinct to sound sophisticated is self-defeating in persuasion. Sophistication serves the speaker's status; simplicity serves the listener's comprehension, and only comprehended messages persuade. The choice is between sounding smart and being understood, and they pull opposite ways.
Brunson cites a study of the 2016 Republican primary speeches run through the Flesch-Kincaid grade-level test.5
Trump averaged a third-to-fourth-grade level. Ted Cruz was at ninth grade; Ben Carson and Mike Huckabee at eighth. Brunson's takeaway: big words may make you feel smarter, but they won't influence others.6
The example is doing real rhetorical work and deserves scrutiny. It's a single study, cited without source, selected to fit — a candidate who won and spoke simply, versus candidates who lost and spoke complexly, presented as proof that simple wins. Correlation, small sample, retrospective selection, and every confound of an election attributed to grade level.7
The example is [UNVERIFIED] and the causal claim is unsupported by it. But — as with the Bannister four-minute-mile — the underlying principle (simpler language is more broadly received) doesn't depend on this example and has independent support. The example is weak; the principle is not.
The third-grade rule isn't about the content being simple — it's about the language being simple, and the distinction matters.8
Brunson elsewhere teaches genuinely complex ideas (ketosis, funnel architecture, belief psychology). The third-grade rule doesn't mean avoid those ideas — it means deliver them in third-grade language. The idea can be sophisticated; the words must be simple.
This is why the "kinda like" bridge exists (the next page's topic): it's the tool for taking a complex idea and delivering it in simple language via analogy. You don't simplify the concept of ketosis; you say ketones are "like millions of little motivational speakers running through your body." Complex idea, third-grade words.
So oversimplification is a translation discipline, not a content restriction. The skill is expressing hard things in easy language, which is much harder than expressing them in hard language — because hard language is where the expert hides. Simple language exposes whether you actually understand the thing, since you can't hide incomprehension behind jargon.
The rule has two edges worth naming.9
The condescension edge: "speak at a third-grade level" can become talking down, treating the audience as children. Done well, simplicity respects the listener's time and attention; done badly, it patronizes. The difference is whether you simplify the language (respectful) or assume the listener is simple (condescending).
The evasion edge is sharper: simple language can smuggle past the complexity where the truth lives. Some things are genuinely complicated, and their honest version requires nuance that third-grade language can't carry. "Ketones are like little motivational speakers" is vivid and elides every caveat about what ketosis actually does and doesn't do. Simplification can be a way to make a claim sound certain by stripping the qualifications that would complicate it.
The honest version simplifies language while preserving the truth, including its uncertainties. The manipulative version uses simplicity to strip nuance that would weaken the sale, delivering a false certainty that the complex truth wouldn't support. The rule rewards vivid simplicity, and vivid simplicity is often achieved precisely by removing the complications — which is fine for a comprehensible truth and a problem for a truth whose accuracy lives in its complications.
Beyond comprehension, simple language does relational work — it signals that you're not performing, which builds trust.9b
Jargon reads as a status display or a hiding place; plain speech reads as candor. When you explain something simply, the listener unconsciously registers "this person isn't trying to impress me or snow me" — which lowers their guard and increases receptivity, independent of whether they understood better.
This is why the simplest communicators often seem the most trustworthy. Complexity invites suspicion (what are they hiding in all those words?); simplicity invites trust (they're just telling it straight). The third-grade rule therefore has a persuasive payoff beyond reception: it positions the speaker as honest.
The edge, of course, is that this trust signal can be faked — deliberate plain-spokenness can perform candor while delivering a stripped, false-certain claim. The most effective manipulators often speak very simply, precisely because simplicity reads as honesty. So simple language is a genuine trust signal and a spoofable one: it makes honest communication feel trustworthy and makes dishonest communication feel trustworthy too, which is why "they spoke plainly" is not evidence that what they said was true. The signal is real, and its realness is what makes it worth exploiting.
You're explaining something and losing people.
Check your language level. Are you using words and concepts above a third-grade reading level? Each one is a place the listener might stop — and stop attending to everything after.
Simplify the language, not necessarily the idea. You can teach complex things; deliver them in simple words. Use analogy ("kinda like") to carry hard concepts in easy language.
Test for the stop-points. Where would a smart non-expert get confused? Those are your comprehension bottlenecks — translate them into plain language or lose the audience past that point.
Then the honesty gate: simplifying language is respectful; stripping the nuance where the truth lives is evasion. When you simplify, ask whether you've removed only difficulty of expression or also the qualifications that make the claim accurate. Vivid simplicity that elides real caveats delivers a false certainty — keep the truth's complications even when you simplify its words.
Clarifying simplicity delivers a complex idea in simple language while preserving its truth, including its uncertainties. The listener understands the real thing better because the language got out of the way. Analogy carries the concept intact.
Stripping simplicity removes not just hard words but the qualifications and caveats where the truth's accuracy lives, delivering a false certainty the complex version wouldn't support. It's simpler and less true.
The test is whether the simplification preserved the truth or only the confidence. If the simple version says something the complex version wouldn't (more certain, fewer caveats), you stripped rather than clarified.
The core principle (simpler language is more broadly received) is well-supported in communication research, though Brunson cites none.10 The Flesch-Kincaid political example is a single unsourced study, retrospectively selected, and its causal claim is [UNVERIFIED].
Tension: simplicity clarifies (deliver hard ideas in easy words) and evades (strip the nuance that complicates the sale). The rule rewards vivid simplicity, which is often achieved by removing caveats — fine for a comprehensible truth, manipulation for a truth whose accuracy is in its complications.
Second tension: the Trump example illustrates the principle and demonstrates the evasion — it strips a complex causal question (why elections are won) down to a single simple factor (grade level), which is exactly the over-simplification the page warns about, performed by the page's own source.
Open question: for genuinely complex truths whose accuracy requires nuance, is there any way to honor both the third-grade-language rule and the truth's complications — or does persuasive simplicity structurally trade accuracy for reception when the subject is genuinely complicated?
Convergence with the kinda-like-bridge and technobabble pages is direct — oversimplification is the goal, the kinda-like bridge is the tool, and technobabble is the failure. Together they form the language layer of the persuasion system.
The tension with the vault's own standards is instructive. The vault prizes nuance, caveats, and precision — the opposite of third-grade simplification. This page is a reminder that reception and precision pull apart: the vault's careful, qualified prose would lose a general audience, and Brunson's vivid simplifications would fail the vault's accuracy bar. The honest middle — simple language, preserved truth — is harder than either extreme, and it's the discipline the page's own honesty gate demands.
To The Kinda-Like Bridge. The kinda-like bridge is the tool that achieves third-grade language for complex ideas — analogy carries the hard concept in easy words. This page is the goal; the kinda-like bridge is the method.
Held together: oversimplification is achieved through analogy — the kinda-like bridge is how you deliver a sophisticated idea in third-grade language without dumbing down the idea itself. This page sets the target (simple language); the kinda-like bridge page provides the mechanism (analogical translation). Neither states it alone: the reason experts can follow the third-grade rule without abandoning complex content is analogy — it's the bridge between the idea's real complexity and the language's required simplicity, which is why the two techniques are a matched pair.
To Emotion First, Logic as Justification. Simple language serves emotional delivery; complex language triggers logical evaluation. Third-grade simplicity keeps the listener in the receptive emotional mode rather than the analytical mode that jargon invites.
The insight neither reaches alone: simple language keeps the listener in emotional-reception mode, while complex language shifts them into logical-evaluation mode — so oversimplification isn't just about comprehension, it's about keeping the emotional channel open. The emotion-first page explains persuasion happens in emotional mode; this page shows simple language sustains that mode. Together: complexity doesn't just lose comprehension, it triggers the analytical scrutiny that emotion-first selling depends on avoiding — which is another reason the third-grade rule matters, and another reason it can shade toward manipulation, since keeping someone in emotional mode also keeps them out of evaluative mode.
Sharpest implication. Speak at a third-grade level — not because the audience is stupid, but because one unfamiliar word makes a listener stop attending to everything after it, so complexity doesn't make you sound smart, it makes you inaudible past the point of confusion. Crucially, this is a language discipline, not a content one: you can teach complex ideas in simple words (via analogy), and doing so is harder than hiding them in jargon, because simple language exposes whether you actually understand the thing. But simplicity has a sharp evasion edge — vivid simplicity is often achieved by stripping the caveats where a complex truth's accuracy lives, delivering a false certainty the nuanced version wouldn't support, and simple language keeps the listener in receptive emotional mode rather than the evaluative mode that would catch the missing qualifications. The honest discipline simplifies expression while preserving truth including its uncertainties; the manipulative one simplifies away the truth.
Generative questions.
For genuinely complex truths whose accuracy requires nuance, is there any way to honor both third-grade language and the truth's complications — or does persuasive simplicity structurally trade accuracy for reception when the subject is complicated?
If simple language keeps listeners in emotional-reception mode and out of evaluative mode, is the third-grade rule partly a technique for deferring scrutiny — and does that make even honest simplification a mild form of the emotion-first bypass?
