Chatter: The Voice in Our Head, Why It Matters, and How to Harness It

Published in 2021, Chatter: The Voice in Our Head, Why It Matters, and How to Harness It by University of Michigan psychologist Dr. Ethan Kross, a member of Kumanu’s Science Advisory Board, offers a fascinating and deeply relatable look at the inner voice that narrates our lives—and what to do when that voice turns toxic.

Drawing on decades of research in psychology and neuroscience, Kross identifies the ways self-talk can sabotage performance, increase anxiety, and erode relationships. But Chatter is more than a diagnosis—it’s a toolkit, filled with science-backed techniques to shift your inner dialogue toward clarity, calm, and resilience.

Why It Matters to Kumanu

At Kumanu, we know that well-being isn’t just about what you do—it’s about how you think. Many of the tools outlined in Chatter are directly integrated into the Purposeful platform, which helps people:

• Reframe inner narratives through purpose-centered reflection
• Gain perspective by visualizing their best selves and long-term goals
• Break negative loops by shifting attention to what truly matters

By guiding users to connect with their personal purpose and values, Purposeful offers practical, daily support for quieting mental chatter and building emotional resilience.

A Book for Our Times

Whether you're navigating professional pressure, parenting stress, or everyday overthinking, Chatter provides tools you can use right now. With engaging stories and actionable strategies, Kross shows that with the right mindset, your inner voice can become a powerful ally instead of an enemy.
