Potential issues
Purpose not captured in database
Changing environment and methods
Data quality
• Over 25,000,000 tags
• Numeric/character format

Conclusion
1. Plenty of data available
2. Metadata = better than memory
3. You may not need another study
• Maybe someone did it already
• Maybe you’re not that bad after all
4. Your neighbors have dirty secrets
