Brand trust is not one thing. Research shows it is two promises: that your brand is reliable, meaning it does what it says, and that it has good intentions, meaning it will look after the customer when something goes wrong. A brand needs both to be trusted. Most brands only work on one.
In a 2003 study, Elena Delgado-Ballester set out to measure brand trust properly. After testing her scale on 221 consumers, she found that trust in a brand consistently splits into two parts. She defined brand trust as a feeling of security that the brand is both reliable and responsible for the customer's interests and welfare. Two distinct promises, both required. Drop either one and trust does not hold.
The first promise is reliability, what the research calls the technical side of trust. It is the belief that the brand will do what it says it will do, consistently. The product works. The service shows up. The quality is the same this time as last time. This is the predictability that lets a customer stop worrying and just choose you.
Reliability is built in the boring, repeatable details: consistent quality, consistent delivery, and a consistent identity that signals all of it. When your brand looks and behaves the same everywhere, it quietly tells people the product behind it is just as steady. Reliability is the price of entry. It earns trust, but on its own it is not enough.
The second promise is intentions, the emotional side of trust. It is the belief that the brand is on the customer's side and will not take advantage of them, especially when something goes wrong. Delgado-Ballester pointed to moments of crisis as the real test: how a brand behaves when there is a problem reveals its intentions. When Coca-Cola faced a contamination scare in Europe, or McDonald's faced fears over beef, the brands that protected and reassured their customers were acting on this second promise.
This is the half most brands ignore until it is too late. Anyone can look trustworthy when things are smooth. Intentions show in how you handle the refund, the complaint, the mistake. That is where a customer decides whether you are merely competent or actually have their back.
If you want to be trusted, work both promises on purpose. For reliability, obsess over consistency: same quality, same experience, same identity, every time. For intentions, design how you behave when things break, because that is the moment that makes or loses trust, and make sure your customer feels protected, not processed.
Trust is the foundation everything else in branding sits on. Build the two promises into how your brand looks, sounds, and behaves through brand strategy and identity, and if you want a brand people genuinely trust, start a project with us.
