Democratic institutions and other important decision-making processes in society have long been designed around the assumption that groups are better at making important decisions than are individuals. But, there is extensive research indicating that group decision making often falls short of its ideal—even when the stakes are high and consequences of the group’s actions are substantial. This briefing note introduces three key biases that impede effective decision making in groups, and seven research-based strategies for mitigating biases in group decision making. Strategies discussed have been demonstrated to enhance the quality of decision making and avoid common pitfalls when making decisions in groups.  

Learning Objective:
This note introduces strategies to mitigate biases in decision making and to encourage consideration of diverse perspectives and information sources. The note provides readily actionable strategies leaders may employ to improve group decision making.
