Ethan Kross opens by reframing the inner voice — including its more critical, anxious moments — as a fundamental feature of human cognition rather than a malfunction to eliminate entirely.

Why this reframe matters:

• Inner speech supports genuinely useful cognitive functions: planning, rehearsing difficult conversations, processing experiences
• The goal isn't silencing this inner voice but managing when it becomes unproductively repetitive or distressing (chatter)
• Distinguishing productive inner dialogue from unproductive chatter is the book's central practical project

This opening sets up the book's central distinction between generally useful inner speech and the specific, unproductive looping Kross calls 'chatter.'
