Why are group decisions so hard? Since the beginning of human history, people have made
decisions in groups—first in families and villages, and now
as part of companies, governments, school boards, religious
organizations, or any one of countless other groups. And
having more than one person to help decide is good because
the group benefits from the collective knowledge of all of
its members, and this results in better decisions. Right? Back to reality. We’ve all been involved in group
decisions—and they’re hard. And they often turn out badly.
Why? Many blame bad decisions on “groupthink” without a
clear idea of what that term really means. Now, Nudge coauthor Cass Sunstein and leading
decision-making scholar Reid Hastie shed light on the
specifics of why and how group decisions go wrong—and offer
tactics and lessons to help leaders avoid the pitfalls and
reach better outcomes. In the first part of the book, they
explain in clear and fascinating detail the distinct
problems groups run into: • They often amplify, rather than correct, individual errors
in judgment
• They fall victim to cascade effects, as members follow
what others say or do
• They become polarized, adopting more extreme positions
than the ones they began with
• They emphasize what everybody knows instead of focusing on
critical information that only a few people know In the second part of the book, the authors turn to
straightforward methods and advice for making groups
smarter. These approaches include silencing the leader so
that the views of other group members can surface,
rethinking rewards and incentives to encourage people to
reveal their own knowledge, thoughtfully assigning roles
that are aligned with people’s unique strengths, and more. With examples from a broad range of organizations—from
Google to the CIA—and written in an engaging and witty
style, Wiser will not only enlighten you; it will help your
team and your organization make better decisions—decisions
that lead to greater success.
