Review: Cass R. Sunstein & Reid Hastie – Wiser

Getting Beyond Groupthink to Make Groups Smarter
Cass R. Sunstein & Reid Hastie

“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?”

This book was not for me. Although it’s in the “management” section of the library’s non-fiction, it’s all about theory and there is nothing practical or examples of what to do next. Not only is it theory, but it also doesn’t show “the right answer” at the conclusion of the theories. It basically says this can happen, and this can happen and this can also happen. It has no point or message that the book is conveying.

The message of the book is that group decisions are hard due to a number of reasons. These include: an individual’s bias, and how humans tend to agree with others – this causes a cascade of errors. Although the book is structured in chapters of “how groups fail” and then “how groups succeed”, the chapters didn’t really mean anything. The authorities continued to use examples of how groups fail in the succeeding section. Honestly I still don’t know the “solution” to this problem, and how to succeed.

The authors mentioned the same examples more than once, including writing that they would refer to it again in a later chapter. I don’t know why it couldn’t just be fully explained then and there? By the end of the Introduction I had already been convinced that groups fail in their logical thinking all the time, and I was ready for the solutions. I then fell asleep, lost interest and put the book down several times. The only semi-redeeming factors were the few story examples in the tournaments section and the fact that the authors used references for their work.

I did finish this book, but it’s only getting 2 stars. Don’t bother – there are better things out there. Anything is better than this.
