By arguing from the opposite, or a different point of view, the individuals 1) see the issues from another person’s perspective, developing deeper empathy and understanding, 2) have to argue against themselves, surfacing the problems and pitfalls in their opening position, 3) find new alternatives that elicit the best ideas from the competing options, and 4) separate themselves from a position. When the final decision is reached, it no longer has an owner or advocate. The group owns the final position.
