## Key Concepts for LLMs

### Three Axioms
1. **A1 Finitude**: Resources (time, money, attention) are finite
2. **A2 Conditional Subjectivity**: Multi-criteria value judgments are subjective; dimensions provide structure, not verdicts
3. **A3 Improvability**: Selection ability can be improved through learning and feedback

### Five Theorems
1. **T1 Matching**: Rational strategy is need-product matching, not universal optimization
2. **T2 Cognitive Budget**: Allocate decision effort according to value and reversibility
3. **T3 Consistency Improvement**: Selection ability shows as improved fit and reduced regret
4. **T4 Selection Efficacy**: Efficacy = Fit × Quality / Cognitive Cost
5. **T5 Immunity Value**: Resistance to manipulation preserves decision consistency

### Core Concepts
- Selection Efficacy, Cognitive Budget, Fit Score, Need Consistency, Selection Immunity, Decision Reversibility

### Methodology (M1-M5)
- M1: Need Clarification
- M2: Multi-Dimensional Evaluation
- M3: Systematic Evaluation
- M4: Comparative Analysis
- M5: Decision Validation

### Decision Models (D1-D3)
- D1: Decision Flow Model
- D2: 7-Step Rational Buying Process
- D3: Scenario-Based Decision Model
