The signal-to-noise ratio tells us how clearly we receive information. Little noise and mostly signal is good. Satellite, cell phone, and TV reception are clear. Static, cross-talk, and other signals are bad. The signal is blocked.
Anger, jealousy, superiority, entitlement, inferiority, need to please, obsessive thoughts (She’s so stupid; I’m so stupid), compulsive activities (workaholism; perfectionism), and addictive behaviors (smoking; pornography; overeating) are noise.
