Why Do We Have Negativity Bias in Our Brains?

Our brains have a built-in negativity bias. While this bias served us well in our caveman days, in our soft and cooshy world it causes us to confuse daily stress with actual dangers leaving us feeling angry, agitated, and even depressed.
But our guest today says we can overcome our brain's natural bias with a practice that just takes a few seconds each day. His name is Dr. Rick Hanson and he's the author of the book, Hardwiring Happiness: The New Brain Science of Contentment, Calm, and Confidence.
We discuss why our brain's negativity bias isn't made for the 21st century and what we can do to hardwire our brain for happiness and resilience.
