Cognitive overload: a state where the total information
Cognitive overload: a state where the total information demanding processing exceeds available working memory capacity, causing performance degradation and qualitatively worse decisions
Why This Is a Definition
This definition precisely establishes cognitive overload by naming the term, identifying its causal mechanism (information exceeding working memory capacity), and describing its consequences (performance degradation, worse decisions). It's specific enough to distinguish from general information overload or stress, and it directly connects to the working memory limitations mentioned in Ultradian and Circadian Cognitive Rhythms and Expertise Transforms Perceptual Chunking.

Cognitive boundaries
Cognitive boundaries determine what information you allow into your thinking process and what you filter out. Without them, every opinion, notification, and news headline colonizes your attention.
Priority systems prevent reactive living
Without a priority system you respond to whatever is loudest rather than what matters most.
The energy cost of context switching
Every context switch depletes energy — batch similar tasks to conserve it.
