Key takeaways
• The picture superiority effect is well established: people remember pictures better than words, because images are encoded both visually and verbally while words are encoded only one way . • John Medina's Brain Rules puts a number on it: information heard is recalled at about 10% three days later, rising to about 65% when paired with a relevant image . • Building slides before storyboarding lets the tool default you into bulleted text, which is the least memorable format available. • The one-visual-per-point rule forces a decision per point: what single image proves this? A point with no provable visual is often a point not worth making. • The artifact is a storyboard table filled in before any design: each row is one point, one visual, and what that visual proves.

Why building the deck first produces a forgettable deck
The order of operations is the whole problem. When you open slide software first, you are not designing an argument, you are filling a template, and the template's path of least resistance is a title and a bulleted list. So you type bullets. The result is a deck optimized for the founder's process of getting thoughts down, not for the prospect's experience of being persuaded. It reads as a list of everything true about your firm, in roughly the order it occurred to you, which is exactly the forgettable capabilities dump that loses to a clearer competitor. There is a memory cost stacked on top of the structure cost. Text-heavy slides are the least memorable way to present, because the prospect is either reading your slides or listening to you, not both, and whatever they retain is text, which decays fast. The point of a deck is to make the case land and survive, and a wall of bullets does neither. It is present in the room and gone by the next morning, which means the expensive work of the call, moving the prospect toward yes, has to be redone from scratch when they try to recall why they were interested.
Section 3
The evidence: why visuals survive when words don't
The case for images is not aesthetic preference, it is one of the more robust findings in cognitive psychology, called the picture superiority effect: pictures are remembered better than their word equivalents. The mechanism, per Allan Paivio's dual-coding theory as summarized by Nielsen Norman Group, is that an image gets stored two ways, as a visual and as a verbal representation, giving memory two retrieval paths instead of one, while a word gets only the single path . More encoding, more recall. This is why the diagram survives the meeting and the bullet does not. John Medina, in Brain Rules, attaches a figure that makes the stakes concrete: when people hear information, they tend to recall about 10% of it three days later, but when that same information is paired with a relevant image, recall rises to roughly 65% . Treat the exact percentages as directional rather than precise, but the direction is not in dispute and the gap is enormous. For a retainer pitch, this is the difference between a prospect who remembers your case a week later when the decision actually gets made, and one who remembers only that the call was "nice." The visual is not decoration on the argument, it is what carries the argument through time. Building that visual discipline into every pitch is the heart of the StoryOS approach.
Section 4
The one-visual-per-point rule
The rule is deliberately strict: each point in your storyboard gets exactly one visual, and that visual must prove the point, not decorate it. One, because two images per point split attention and dilute recall, and because the discipline of choosing a single image forces you to know what the point actually is. Prove, because a stock photo of a handshake is not a visual, it is wallpaper: it carries no information and earns no memory. The image has to be evidence, a before-and-after chart, a real screenshot of a client dashboard, a simple diagram of your process, a photo of actual work. The strictness produces a useful side effect. When you cannot find a single image that proves a point, you have usually found a point that is not provable, which means it is a claim the prospect will discount anyway. "We're highly experienced" resists visualization because it is an assertion, not evidence. "We took this client from an eight-day close to three, here's the chart" visualizes instantly because it is a fact. The one-visual-per-point rule is therefore also a filter for weak claims: points that can't earn an image often shouldn't be in the pitch. That filtering is why the rule improves the argument, not just the slides.
Section 5
The artifact: the pre-design storyboard
Fill this in on paper or in a plain document before you touch slide software. One row per point. Do not design anything until every row is complete. The sequence is the storyboard: a case that moves from the prospect's problem, to proof you can solve it, to the concrete how, to the ask. Only once the rows are complete do you open slide software, and then the design job is simple, one clean slide per row, one visual, minimal words. Notice the deck shrank from forty text slides to a handful of visual ones, and it got more persuasive, because each slide now carries an image the prospect will actually remember instead of a paragraph they'll forget. The honest limit: a striking visual that proves nothing is worse than a plain one that proves something, so beauty is not the target, evidence is. A chart of a real result beats a gorgeous illustration of an abstraction every time.
Section 6
You've storyboarded the call right when…
You've storyboarded it right when the sequence of points existed on paper before you opened any slide software, and it moves the prospect from their problem to your ask in a logical order rather than the order your thoughts arrived. You've storyboarded it right when every point has exactly one visual and that visual is evidence, a chart, a screenshot, a diagram, not a stock photo standing in for an idea. You've storyboarded it right when you dropped the points that couldn't earn a provable image, because you recognized them as claims the prospect would discount anyway. And you've storyboarded it right when your deck shrank to a handful of visual slides that a prospect could describe accurately a week later, which is the only version of a pitch that survives long enough to win the deal.
