+- **Proprietary Interests:** Some sources proprietary (Glassdoor, Payscale)
+
+**Cultural/Social Bias:**
+- **Geographic Bias:** U.S.-centric (better data coverage); Western Europe overrepresented
+- **Social Perspective:** Knowledge worker focus excludes non-knowledge sectors
+- **Language Bias:** English-language sources predominate
+- **Selection Bias:** "Knowledge worker" definition varies by source
+
+**Transparency:**
+- **Bias Disclosure:** Data gaps acknowledged; confidence levels provided
+- **Limitations Stated:** Comprehensive limitation documentation
+- **Raw Data Available:** Source links provided; original data at individual sources
+
+### Reliability Assessment
+
+**Consistency:**
+- **Internal Consistency:** Cross-source validation performed
+- **Temporal Consistency:** Not applicable (single snapshot)
+- **Cross-source Consistency:** Reasonable agreement for U.S. (±10%); wider variation globally
+

+
+**Accuracy for Different Uses:**
+- **Point Estimates:** Reliable for U.S. averages; moderate for global
+- **Trend Analysis:** Limited (single snapshot with YoY growth rates)
+- **Cross-sectional Comparison:** Reliable for U.S. sectors; moderate for cross-country
+- **Sub-population Analysis:** Limited (sector-level; no demographics)
+
+---
+
+## Known Limitations and Caveats
+
+### Coverage Limitations
+
+**Geographic Gaps:**
+- Africa (minimal data available)
+- Middle East (limited coverage)
+- Rural areas (knowledge workers concentrated in urban centers)
+
+**Temporal Gaps:**
+- Single snapshot (2024-2025)
+- No historical time series
+
+**Population Exclusions:**
+- Non-knowledge workers (by design)
+- Informal economy knowledge workers
+- Gig economy workers (partial coverage)
+
+**Variable Gaps:**
+- Equity compensation not captured in most sources (stock options, RSUs)
+- Benefits variation across countries
+- Demographic breakdowns limited
+
+### Methodological Limitations
+
+**Sampling Limitations:**
+- Varies by source (BLS high quality; self-reported surveys lower quality)
+- Self-selection bias in Glassdoor, Payscale user-generated data
+
+**Measurement Limitations:**
+- "Knowledge worker" definition inconsistent across sources
+- Purchasing power parity adjustments not uniformly applied
+- Exchange rate fluctuations affect cross-country comparisons
+
+**Processing Limitations:**
+- Aggregation across sources with different methodologies
+- Confidence levels estimated (not statistically rigorous)
+
+### Comparability Limitations
+
+**Cross-national Comparability:**
+- Definitional differences (what constitutes "knowledge worker")
+- PPP adjustments needed for true cost-of-living comparisons
+- Tax and benefit systems vary (gross vs. net compensation)
+
+**Temporal Comparability:**
+- Single snapshot (cannot assess trends)
+
+**Sub-group Comparability:**
+- Limited demographic data (gender, race, education level)
+
+### Usage Caveats
+
+**Inappropriate Uses:**
+1. **DO NOT use for precise individual salary negotiations** - broad averages only
+2. **DO NOT assume global estimates are highly accurate** - medium confidence (65%)
+3. **DO NOT use for historical trend analysis** - single snapshot
+4. **DO NOT assume equity compensation included** - most sources cash compensation only
+5. **DO NOT use without PPP adjustment** - cross-country comparisons need cost-of-living adjustment
+
+**Ecological Fallacy Risks:**
+- National/sector averages do not reflect individual company or role compensation
+- Regional averages mask within-country variation
+
+**Correlation vs. Causation:**
+- Compensation levels do not imply causation
+- Appropriate for descriptive analysis only
+
+---
+
+## Recommended Use Cases
+
+### Ideal Applications
+
+**Research Questions Well-Suited:**
+1. "What is the global knowledge worker compensation market size?"
+2. "How do U.S. tech salaries compare to European tech salaries?"
+3. "What is the AI/ML skills premium in 2025?"
+4. "What percentage of the U.S. workforce are knowledge workers?"
+
+**Analysis Types Supported:**
+- Descriptive statistics (compensation averages by geography/sector)
+- Cross-country comparison (regional salary differences)
+- Sector analysis (technology vs. finance vs. healthcare)
+- Skills premium analysis (AI/ML vs. general software engineering)
+
+### Appropriate Contexts
+
+**Geographic Contexts:**
+- U.S. national analysis (high confidence)
+- Western Europe comparison (medium confidence)
+- Global overview (medium confidence)
+
+**Temporal Contexts:**
+- Current snapshot (2024-2025)
+- Short-term growth trends (YoY)
+
+**Subject Contexts:**
+- Knowledge economy labor markets
+- Technology sector compensation
+- STEM workforce analysis
+- Consulting and professional services
+
+### Use Warnings
+
+**Avoid Using This Source For:**
+1. **Individual salary negotiation** → Use role-specific Glassdoor, Payscale
+2. **Historical trend analysis** → Single snapshot; need time series data
+3. **Precise global estimates** → Medium confidence (65%); use OECD, ILO for official stats
+4. **Equity compensation analysis** → Most sources exclude stock options/RSUs
+5. **Demographic analysis** → Limited demographic breakdowns
+
+**Recommended Alternatives For:**
+- U.S. official statistics → BLS OEWS (Occupational Employment and Wage Statistics)
+- Global official statistics → OECD Average Wages, ILO Global Wage Report
+- Tech sector depth → Dice Tech Salary Report, Stack Overflow Developer Survey
+- Equity compensation → Carta Equity Report, Glassdoor total compensation
+- Real-time data → Glassdoor, Payscale (updated continuously)

+## Cataloger Notes
+
+**Internal Notes:**
+- Unique tertiary source; multi-agent research compilation
+- U.S. data high confidence (85%); Global medium confidence (65%)
+- Future updates require re-research (not automated)
+- Consider annual update schedule (October/November)
+- Equity compensation gap noted (most sources exclude stock options/RSUs)
+
+**To Do:**
+- [ ] Annual update (October 2026) with new research cycle
+- [ ] Consider adding demographic breakdowns if data becomes available
+- [ ] Explore equity compensation data sources (Carta, Glassdoor total comp)
+- [ ] Add Africa and Middle East data if sources improve
+
+**Questions for Review:**
+- Should this be updated quarterly or annually?
+- How to handle exchange rate fluctuations in cross-country comparisons?
+- Should we add PPP-adjusted values?
