Cognitive Noise
Clear thinking begins by reducing interference.
Shrink Definition
Cognitive noise is the collection of internal and external distractions that reduce the clarity, consistency, and accuracy of thinking. It includes irrelevant thoughts, emotional interference, interruptions, environmental distractions, competing priorities, and mental clutter that obscure useful information. Cognitive noise doesn't eliminate intelligence. It makes intelligence harder to access.
Plain language
Your best thinking is often hidden beneath unnecessary mental noise.
Shrink Insight
The goal isn't more thinking. The goal is less unnecessary thinking.
Why it matters

Common misunderstanding
People often believe they need better thinking. Sometimes they simply need fewer competing signals.

Medical boundary
This concept is educational and shouldn't be used to self-diagnose. It doesn't replace care from a licensed clinician. Symptoms, medication, and treatment decisions should be discussed with a qualified professional, and emergency symptoms require emergency care.
Evidence summary
Although "cognitive noise" is used here as an educational framework, it reflects established findings in attention research, human factors, executive functioning, and cognitive psychology demonstrating that irrelevant information degrades cognitive performance.
