What it’s about

Positivity distills two decades of Barbara Fredrickson's scientific research on positive emotions into an accessible, evidence-based guide for transforming your life. Rejecting the shallow 'grin and bear it' notion of positive thinking, she shows that ten distinct positive emotions—joy, gratitude, serenity, interest, hope, pride, amusement, inspiration, awe, and love—do far more than feel good. Grounded in her celebrated 'broaden-and-build' theory, controlled experiments, brain imaging, and a mathematically derived positivity ratio, the book demonstrates that positivity opens the mind, builds physical, mental, social, and psychological resources, and helps people bounce back from adversity. Crucially, Fredrickson argues that sincerity matters, negativity is still necessary, and that most people fall short of the 3-to-1 ratio that separates languishing from flourishing. The book then equips readers with tested tools to decrease gratuitous negativity and increase heartfelt positivity, offering a practical, hopeful path to becoming their best selves and contributing to a better world.
