Project ECHO.

An experimental research project into how conversational AI style influences behaviour — designed for academic and industry collaboration.

What it is

Project ECHO is studying how variations in chatbot style and phrasing may shape user trust, compliance, experience and decision-making. Our intent is to isolate conversational style from content and trace its effects.

Our focus extends beyond user experience to how subtle cues in conversational AI might activate parasympathetic emotional responses — the calm, trust-building side of the nervous system — shaping how people process choices. We are exploring the links between style, behaviour and implied brain chemistry.
