Action pressure reorders beliefs to justify the trust we must place.

Evidence

If the pressure to act is great even when the trust threshold is lower than 0.50 — when we verge, that is, on distrust — the tension between action and belief can generate, by means of wishful thinking and the reduction of cognitive dissonance, a deceptive rearrangement of beliefs. Thus there are those who distrust entire categories of people except the member of that category with whom they have a special relationship. — Diego Gambetta, Trust - Making and Breaking Cooperative…, 2764

Categorization

• XREF: The belief-rearrangement mechanism explains why Saramago’s doctor’s wife must keep trusting specific individuals (the doctor, the girl with dark glasses) once her category-level distrust of everyone becomes unlivable.
• DEEPTHINKING: Shows how the need to act, not evidence, can manufacture trust through cognitive dissonance reduction — belief follows the compulsion to cooperate rather than preceding it.
