Trust Can’t Be Generated.

I have spent thirty years in the trust business. I just didn’t call it that at the time. I called it marketing.

This week in Ad Age, Raja Rajamannar, Mastercard’s former CMO, made the case that trust is now marketing’s only true differentiator. AI makes every brand more persuasive. It doesn’t make any of them more believable.

He’s right. But knowing trust matters is the easy part. The hard part is building it.

Three things decide that. He didn’t get to them.

1. Trust is a record.

In the 1990s I had to sell something nobody wanted to talk about. Life settlements. A financial product built around a conversation about dying.

No headline was going to fix that. No clever line. No amount of reach.

What fixed it was a face. Betty White put her name, her reputation and her voice behind The Lifeline Program for a decade. People didn’t trust the product first. They trusted her. Then they trusted us, because she did.

That’s how trust works. It transfers. It’s borrowed before it’s owned. And it’s earned slowly, in public, with something at stake.

You can generate content. You can’t generate a track record.

2. AI needs direction.

AI doesn’t have a vision. It has a prompt.

Give it no direction and it hands you the average of everything it’s ever seen. Polished. Plausible. Forgettable.

Garbage in, garbage out. That rule is older than the internet, and AI didn’t repeal it. It made it faster.

The tool is extraordinary. In the right hands it’s the best creative partner this industry has ever had. But it has to be managed like one. Told where we’re going. Told what we’re not doing. Told when it’s wrong.

That takes someone who already knows what good looks like.

If you aren’t creative, AI won’t make you creative. It’ll make you prolific.

If you are, it makes you unstoppable.

3. The machine is reading your record too.

Here’s the part most brands haven’t caught up to.

The first impression of your brand is increasingly written by an AI. A buyer asks ChatGPT or Perplexity what to choose, and the machine hands back one answer.

The research shows it favors brands it can describe with confidence: named sources, real expertise, third-party proof, a consistent story told the same way everywhere. I laid out the numbers in The Answer Layer.

In other words, a record.

Trust used to be earned from people. Now you earn it from people and the machines that answer for them. The work is the same. The audience doubled.

Sometimes it’s what you don’t say.

Use every tool. AI, data, media, talent. I do.

But tools don’t build trust. Brands do. A strong brand tells people what to expect before you’ve said a word, and then keeps that promise every time.

And sometimes the strongest thing a brand says is what it doesn’t. The claim you don’t make. The trend you don’t chase. The celebrity you don’t sign. The campaign you kill the week before launch.

Audiences can’t see those decisions. They feel them.

That’s what taste is. Not decoration. Knowing what your audience will believe coming from you, and having the discipline to protect it.

What I’d tell a client this quarter.

Put a real name behind it. A founder, an expert, a face that’s accountable. Anonymous brands are easy to doubt and easy to replace.

Direct the machine. Decide where the work is going before you open the tool.

Say less, prove more. Specific claims. Named sources. Numbers you’d defend in a deposition.

Protect the record. Every shortcut is a withdrawal, and the internet doesn’t forget.

The brands that win the next decade won’t be the ones that produce the most.

They’ll be the ones people, and machines, believe.
