The most sophisticated early warning systems create information architectures that surface important signals while filtering noise. Understanding these architectures helps build more effective systems.
The Peripheral Vision Principle
Direct focus misses peripheral changes. The best early warning systems monitor edges and intersections where change typically begins.
Nancy structured her monitoring around peripheries: - Geographic peripheries (emerging markets affecting developed ones) - Industry peripheries (startups disrupting incumbents) - Regulatory peripheries (pilot programs before broad implementation) - Social peripheries (subcultures before mainstream adoption)
Changes at peripheries provided 6-18 month warning of mainstream disruption.
The Weak Signal Amplification Method
Important early signals are often weak and easily missed among noise. Effective systems amplify weak signals through correlation and pattern matching.
Brian built amplification into his system: - Single mentions triggered keyword tracking - Multiple mentions from different sources triggered investigation - Correlated mentions across domains triggered deep analysis - Pattern emergence across time triggered action planning
This amplification surfaced important signals before they became obvious.
The Triangle Confirmation Protocol
Single source information can mislead. Triangle confirmation requires signals from three independent sources before triggering response.
Catherine's triangle sources: 1. Human intelligence (network contacts) 2. Data indicators (quantitative signals) 3. Media analysis (sentiment and coverage)
Only when all three aligned did she consider signals validated.
