Missing confidence saps diffuse sentiment while missing trust blocks decisive action.

Evidence

Given these conditions the relation between confidence and trust is once again important. The large functional systems depend not only on confidence but also on trust. If there is a lack of confidence there will also be a diffuse sentiment of dissatisfaction and alienation or even anomie. This may have no immediate impact on the system. If trust is lacking, however, this changes the way people decide about important issues. Trust, as may be recalled, is an attitude which allows for risktaking decisions. — Diego Gambetta, Trust - Making and Breaking Cooperative…, 1427

Categorization

• XREF: Directly supplies Luhmann’s confidence/trust distinction that pairs with Hardin’s point that trust requires observable constraints; trust enables risk-taking.
• DEFINE: Precisely defines how trust differs from confidence: trust permits risk-taking decisions, confidence is background reliance.
