‘Essential reading for creators, builders, and leaders’
DANIEL H. PINK, author of Drive

‘A deep dive into the dynamics of successful teams’
ADAM GRANT, author of Think Again

‘A phenomenal, science-backed guide’
KATY MILKMAN, author of How to Change

We live in an age of unprecedented individualism. We seek individualistic solutions to our problems, but we can rarely explain failures and successes by looking at one person’s actions, or fix things entirely on our own. Our lives are shaped by groups as wide-ranging as work teams, friends and families, nationalities and religions, and our tendency toward cooperation is the foundation of human accomplishment. Nearly every scientific discovery, world-changing business, desert island musical album and legendary sports team has a great group at its core.

In his revelatory book, Dr Colin Fisher, a foremost expert on group dynamics, demonstrates how to harness the amazing power of groups to achieve great things under the right conditions. Fisher skilfully weaves together the latest science with vivid storytelling. He demonstrates how to build happy groups that cooperate effectively, how to harness the motivating power of competition without getting embroiled in conflict and avoid the pitfalls of conformity.

The Collective Edge is a ground-breaking book that will transform your understanding of human behaviour. Whether you want to change yourself, your team, or the world, you need to work with the invisible forces of group dynamics, rather than being unwittingly pushed around by them. By doing so you can learn to make better decisions, form happier groups that are more than the sum of their parts, and improve the quality of your interactions with others – forever changing how you live and work for the better.
