A technique I use regularly (mostly for decision-making in meetings) and successfully is the five finger approach. Essentially, people have to hold up a number of fingers showing how strongly they feel about the decision that is proposed. If they strongly oppose it they can do, but they have to offer an alternate proposal at the same time. What works very well about this is that it moves people away from “do I support this, and is this the perfect proposal?” to “do I hate this enough to block it?” As such, I think it’s similar to the article’s approach – the default decision (in the absence of strong disagreement) becomes a yes.
