Consensus versus Collective Decision Making

From the excellent book Wisdom of Crowds by James Suroweicki:

Collective decision making is often confused with a quest for consensus. But they are different. Here’s how they contrast:

Consensus	Collective Decision Making
Encourages lowest-common-denominator solutions which offend no one.	Encourages the free exchange of conflicting views, which excites everyone.
Tends to stick with the familiar and squelch provocative debate.	Explores the unfamiliar and stimulates provocative debate.
“Can’t we all get along” approach.	“Promote diversity” approach.
Watered-down solutions.	Innovative solutions.
Keep your real opinions to yourself.	Express your real opinions
