What is information overload cost?

Information overload cost is a concept in personal epistemology: Every minute spent consuming noise is a minute stolen from depth. The cost of staying informed about everything is understanding nothing well enough to act on it.

Example: A product manager reads five industry newsletters, three Slack channels, two subreddits, a curated Twitter list, and a daily news digest — every morning before starting actual work. She can reference any topic in a meeting. She sounds informed. But when asked to make a strategic recommendation on her own product's positioning, she defers. She needs "more data." She always needs more data. Her breadth of awareness has become a substitute for the depth of understanding that decisions require. She is not informed. She is saturated. And saturation feels like knowledge until someone asks you to act on it.

This concept is part of Phase 7 (Signal vs Noise) in the How to Think curriculum, which builds the epistemic infrastructure for signal vs noise.
