We discovered that averaging the answers of the groups after they reached consensus was much more accurate than averaging all the individual opinions before debate.

我们发现，在达成共识后对小组的答案进行平均比在辩论前对所有个人意见进行平均要准确得多。

It's true that reviews are only individual opinions, but if a business has 30 or 50 or 100 reviews, well you get a general idea what people think of this particular business or restaurant.

诚然，评论只是个人意见，但如果一家企业有 30 条、50 条或 100 条评论， 那么您就会大致了解人们对这家特定企业或餐厅的看法。
