The Structure of Promises: How to Make People Believe You

Every good presentation makes a promise. But most promises are weak. They’re vague, implied, and forgettable. Chapter 7 is about fixing that.

Kennedy says your Irresistible Offer (from the previous chapter) is really just a way to fulfill a promise. The offer is the how. The promise is the why anyone cares. If the promise is weak, the offer doesn’t matter. Nobody wants the cure if they don’t believe they’re sick.

He gives his own example. When presenting his Magnetic Marketing System to small business owners, he would say something like: “After today, you will never again spend a dollar on advertising without knowing it directly brings you customers, sales, and profits.” That’s a bold, clear, personal promise. Not “learn some marketing tips.” Not “discover new strategies.” A direct statement about how your life changes.

So how do you build promises like that? Kennedy lays out four structures.

1. Big Stated Promises vs. Small Implied Ones

This is the most common mistake. People make small, timid promises that imply a benefit instead of stating it directly.

Here’s what a weak promise looks like: “Learn how to boost your immune system.” It’s fine. It’s accurate. But it’s boring. The benefit is left for the audience to figure out on their own.

Now here’s the same idea as a big stated promise: “Discover the secrets of people who never get sick.”

See the difference? Same topic. But the second version tells you exactly what you get. It’s personal. It’s bold. It paints a picture.

Kennedy gives another pair. Weak version: “50 tips for a more bountiful garden.” Big version: “Get 50 tips from master gardeners and grow twice the garden for half the cost, and make your neighbors green with envy.”

The pattern is simple. Take whatever you’re offering and ask: what does this actually do for the person sitting in the audience? Then say that. Out loud. Don’t make them connect the dots. Connect the dots for them.

I saw this constantly during my years in IT. Engineers would present a new tool and say something like “improved monitoring capabilities.” Nobody cares about that. But “you’ll get paged 60% less at 3 AM” hits different. Same tool. Better promise.

2. Promises Framed as Questions

Sometimes you can’t or don’t want to make a direct bold claim. Maybe the topic is sensitive. Maybe legal is watching. Maybe you just feel weird being that direct.

Kennedy’s solution: frame the promise as a question.

Instead of “You can get rich fast,” try: “Did you know there’s a new millionaire explosion going on right now? More ordinary people became millionaires this year than any prior year. Do they share a secret? If you knew their secret, would you be willing to follow simple directions and invest as little as one hour a day?”

The audience hears the promise. They don’t really register the question marks. The promise is what sticks. The questions just make it feel less like a sales pitch.

This is a useful technique when you need to be careful with claims. In tech, for example, you might not be able to say “This will save your company $2 million.” But you can ask: “What if you could cut your infrastructure costs in half? What would your team do with that budget?”

Same effect. Less risk.

3. Primary and Secondary Promises

One promise is good. One promise backed by three to five supporting promises is much better.

Kennedy uses his marketing system again as an example. The primary promise for salespeople was: “Put an end to cold prospecting once and for all.” Strong on its own. But then he stacks secondary promises on top:

• Now you can invest 100% of your time actually selling, not hunting for someone to sell to.
• You can double or triple your income when you stop wasting time on prospecting.
• You’ll be home on time for dinner. Your spouse and kids will notice the difference.

See what happened? The primary promise is about business. The secondary promises hit personal life, income, time, and status. They paint a complete picture of what changes.

The rule of thumb Kennedy gives is three to five secondary promises for each primary one. That feels right to me. Enough to build the vision, not so many that people tune out.

4. Complex Stacked Promises

This is the most ambitious structure. You take two or more standalone promises and combine them into one bigger statement.

Kennedy points to classic book titles as examples. “How to Win Friends and Influence People.” That’s two promises stacked together. Either one works alone. Together, they’re more than the sum of their parts.

Or “Think and Grow Rich with Peace of Mind.” Getting rich is one promise. Having peace of mind is another. Together, they answer the objection before it’s even raised. “Sure, I want to be rich, but I don’t want the stress.”

He gives a luxury vacation club example that stacks five promises: you stay in magnificent mansions (not hotels), with complete privacy, prepared to your liking, all-inclusive with no hidden charges, and satisfaction guaranteed. Each promise handles a different objection. Each one builds on the last.

Kennedy notes that stacked promises work especially well in presentations where you have a captive audience. In advertising, people’s attention is short. But when someone is sitting in your webinar or your conference room, you have time to build a complex promise, repeat it, break it apart, and put it back together.

The Big Picture

Here’s what ties this chapter together. Your promise is the beginning of your presentation. Your Irresistible Offer is the end. Everything in between is a bridge that walks the audience from “that sounds amazing” to “here’s how you get it.”

Kennedy literally calls it leading them to The Promised Land.

After 20 years in tech, I’ve sat through hundreds of presentations. The ones I remember all had one thing in common. They made a clear, bold promise early on and then spent the rest of the time proving they could deliver on it. The ones I’ve forgotten made no promise at all. They just showed slides.

If you only take one thing from this chapter: stop implying benefits. State them. Boldly. Personally. Make the audience see their own life getting better. Then show them how.
