The Trust Equation
A framework for measuring trust: (Credibility + Reliability + Safety) ÷ Self-Orientation.
The Trust Equation is a structured way to think about trust. The formula is:
Trust = (Credibility + Reliability + Safety) ÷ Self-Orientation
Credibility refers to expertise and competence — whether people believe you know what you're talking about. Reliability is about consistency and follow-through — whether people can count on you to deliver. Safety measures whether people feel comfortable being candid with you. Self-Orientation is the denominator — it reflects how much focus is directed toward your own interests versus others' needs.
Vizuna keeps the same underlying idea, but in user-facing product language the fourth dimension is shown as Selflessness so the score reads more intuitively. The equation's power is still in the denominator: even high credibility, reliability, and safety scores are diminished when self-focus dominates the interaction.
How Vizuna measures this
Vizuna operationalizes the Trust Equation through its CRSS framework (Credibility, Reliability, Safety, Selflessness in user-facing copy), measuring each dimension through self-assessments and, where enabled, source-protected colleague reflections over time.
