5.7 — Law #4: Trust (The Final Decision Layer)
Once identity + language + culture align, the buyer crosses into trust evaluation.
This is where the Trust Utility Equation takes over:
Trust Utility = P(outcome) × Value – Risk
If they believe:
- “This person gets my world.” → identity match
- “This person speaks my language.” → linguistic match
- “This person understands my culture.” → cultural match
- “This will probably work for me.” → P(outcome)
- “This seems worth it.” → value
- “I won’t get burned.” → low risk
Trust forms instantly.
If any of these collapse,
trust collapses.
Trust is the fourth law.
