When Forming New Groups, Focus on Two Critical Moments: Jeff Polzer, the Harvard Business School professor who studies organizational behavior (see Chapter 8), traces any group’s cooperation norms to two critical moments that happen early in a group’s life. They are: 1. The first vulnerability 2. The first disagreement These small moments are doorways to two possible group paths: Are we about appearing strong or about exploring the landscape together? Are we about winning interactions, or about learning together?
