Delegate peripheral scanning to AI, reserve deep attention for core domains

Why This Is a Rule

You need breadth to spot cross-domain patterns and emerging trends. You need depth to develop genuine expertise and produce original insight. Human attention cannot do both at scale — spreading attention across many domains produces shallow familiarity with everything and mastery of nothing.

AI changes this equation. It can scan peripheral domains (adjacent fields, emerging trends, tangential research) at machine speed, filtering for signals relevant to your core work. This frees your limited human attention for deep engagement where it matters most: 2-3 sustained, generative sessions per week in your core domains.

The division is architectural: AI handles breadth (low-resolution scanning across many domains), humans handle depth (high-resolution engagement in few domains). Neither can substitute for the other. AI scanning without human depth produces well-informed shallowness. Human depth without AI scanning produces expert tunnel vision.

When This Fires

• You follow more sources than you can actually read each week
• You want to stay current in adjacent fields without losing focus on your core work
• You're spending more than 30% of your reading time on peripheral scanning
• Important cross-domain connections are reaching you too late because you can't monitor everything

Common Failure Mode

Using AI to scan everything, including your core domains. AI summaries of your core domain are dangerously shallow — they compress nuance, miss context you'd catch, and create an illusion of staying current without the depth that produces insight. Deep engagement means reading primary sources, wrestling with arguments, and writing responses — not reading summaries.

The Protocol

Define two lists: (1) Core domains — 2-3 areas where you need depth; schedule deep reading and writing sessions for these. (2) Peripheral domains — areas where you need awareness but not mastery. Set up weekly AI scanning (RSS + summarization, research digests, automated monitoring) for peripheral domains. Review the filtered output in 15-20 minutes. If a peripheral signal becomes important enough to warrant depth, promote it to your core list — don't just read more summaries.
