Brand Promise: Slayer of Trust

Don’t give your consumers a reason to become activists.

A consumer does not wake up one morning and decide to become an activist against your brand.

They begin as something far more valuable: a believer. They saw your advertisement, heard your promise, chose you over someone else, recommended you to their family, or returned to you year after year.

Perhaps, in a category involving their health, their children, or their wellbeing, they placed something even more valuable than money in your hands: their trust. Then they discover that what they were promised is not what they received. That is when the relationship changes. It rarely begins with a protest.

It begins with a question: Is this really what they said it was? Then another: Why does the label say one thing and the product deliver another? Then comes the search, the comparison, the review, the video, the comment section, and, increasingly, the discovery that they are not alone. One disappointed consumer finds another. Before the brand fully understands what is happening, the people who once bought the product are no longer simply customers; they are investigating it.

The most important lesson for brands today is simple: don’t give your consumers a reason to become activists. They were not your enemy. They chose you because they believed you.

A Brand Is Not a Slogan. It Is a Promise.

Allen Adamson, the former chairman of Landor Associates, once put it simply: “A brand, for every intent and purpose, is a promise.” That sentence should make every marketer uncomfortable because a promise is not harmless advertising language. The moment a consumer believes it, an expectation is created, and the underpinning of that expectation is trust. As Adamson argues, consumers are primed to believe that a brand will deliver what it promises and that the company behind it will make things right when something goes wrong.

That is why trust cannot be treated as another asset on a balance sheet. You can build a factory, buy media, hire celebrities, and create a campaign, but trust is built only when the promise and the experience continue to meet.

And when they don’t, the damage is not always dissatisfaction.

Sometimes, it is something much worse: betrayal.

A bad experience can be forgiven. A delayed delivery can be explained. A product defect can be corrected. But when consumers believe that a brand knowingly persuaded them with a promise that was not true, the question changes. They stop asking, “What went wrong?” and start enquiring, “What else did you not tell us?”

When the Promise Becomes the Evidence

Let’s understand this with a few examples. For years, Volkswagen promoted “Clean Diesel”, giving consumers the promise that they could enjoy performance while making a more environmentally responsible choice.

Consumers were not simply buying a car; they were buying into an idea. Then regulators found that more than 550,000 Volkswagen and Audi diesel vehicles in the United States had been deceptively marketed as low-emission and environmentally friendly while being fitted with illegal emission defeat devices designed to mask high emissions during government testing.

The consumer redress programme eventually repaid more than $9.5 billion to affected buyers. The financial consequences were enormous, but the deeper lesson was even more damaging: the promise that helped sell the product became part of the evidence against the brand.

That is what every boardroom needs to understand: a broken brand promise is not simply a failed advertisement. The stronger the promise, the greater the responsibility to honour it.

When Health Enters the Promise, the Responsibility Changes

India has seen how fragile consumer trust can become when questions about food and safety enter the public conversation. MAGGI is one of India’s most emotionally connected brands. For generations, it has represented more than instant noodles; it represents childhood, convenience, home, familiarity, and trust.

That is why the MAGGI crisis of 2015 became much bigger than a regulatory dispute. When concerns were raised about lead levels and the “No Added MSG” claim, the product was withdrawn from the market amid growing consumer confusion. The Bombay High Court later overturned the ban and required fresh testing. Subsequent court-mandated testing found the tested samples within permissible safety limits, allowing MAGGI to return to the market.

The lesson is important precisely because this was not a simple case of proven, deliberate consumer deception. It demonstrated something equally significant. When consumers begin questioning whether a product they have trusted for years is safe, the brand is suddenly fighting for something far more important than market share.

It is fighting for permission to be trusted again. MAGGI’s eventual return also offers the other side of the lesson: a strong emotional relationship can help a brand recover, but no brand should ever assume that emotional capital gives it permission to take consumer trust lightly. When food and health enter the conversation, consumers do not behave like passive customers; they become deeply personal stakeholders.

You Cannot Play with Health

And this is where the warning becomes even more serious. A consumer choosing between two soft drinks may be making a preference decision. A consumer making a decision based on a health claim is doing something entirely different. They may be trusting information they cannot independently verify and may not have the scientific knowledge to challenge the claim. That is precisely why the responsibility of the brand must be higher.

India’s Patanjali misleading-advertising proceedings brought this issue into sharp public focus. In 2024, the Supreme Court examined advertisements and claims relating to the purported medicinal efficacy of products and recorded restrictions on advertising or branding products as curing specified diseases and disorders.

The broader lesson for brands is bigger than one company or one court case. The more consequential the promise, the less room there is for marketing exaggeration. When you sell health, you are not selling a slogan; you are asking someone to trust you with a decision that may affect their life. You cannot exploit fear and call it positioning. You cannot manufacture reassurance and call it branding.

And you cannot play with a consumer’s health and expect marketing to repair the damage once consumers begin asking questions. That is not aggressive marketing. It is a dangerous misuse of trust.

Here is the question every leadership team should ask before approving a brand promise:

Can we defend it?

Because consumers today don’t just receive brand communication. They question it. They search it. They compare it. And when something doesn’t add up, they talk.

PR can manage the crisis. Advertising can tell a new story. Influencers can shift the conversation. But none of them can permanently repair trust if the behaviour behind the promise hasn’t changed.

That is the real risk for the boardroom.

A brand promise creates an expectation. The moment the consumer discovers a gap between what was promised and what was delivered, the conversation changes. And sometimes, the very people who trusted the brand most become the ones asking the hardest questions.

That is why the line between marketing and accountability is becoming thinner.

The consumer is not your enemy. They are the reason the brand exists.

They gave you their money. More importantly, they permitted you to occupy a place in their lives. That permission is earned through consistency, not clever communication, because the promise that brings a consumer to your brand can also be the very thing that turns them against it.

Don’t give your consumers a reason to become activists.
