Why It Matters.

Conversational AIs increasingly mediate decisions in enterprise, education and public services.

Even small shifts in conversational style—such as apologies, hedging (cautious language such as “might” or “seems”), assertiveness, affirmation or encouragement—can influence trust, authority and the perception of fairness.

These effects are reflected in people's behaviour: whether they comply, challenge or mirror the AI. From such shifts we can infer the underlying neurochemical responses at play—without measuring brain chemistry directly.

Unlike weighty academic papers or the closed-door knowledge inside the firewalls of big tech, Project ECHO brings an open, user-centred lens. We combine the flexibility of a startup with decades of experience design and deep industry expertise.

Our commitment is to be transparent about our results, share our methodologies and actively invite scrutiny and collaboration.

The rate of AI-driven change continues to accelerate — seemingly exponentially — and we are not aware of anyone else initiative with contributions these tonal and behavioural effects in quite this way.
