Your theory really only works for places with a large amount of reviews (positive or negative). When you have only a handful of reviews, the need for authenticity grows because they carry much more weight. You would need much more data points to avoid the noise of fake reviews. |

"Did you hear about restaurant x?"
"They suck. Don't go there."
If you've only got one friend who's been there, that's all the data you have. At least with Yelp, you can see reviews from people you've never met. The big difference between Yelp and any other form of word-of-mouth advertising is that the business owner can actually see the reviews people are giving to others.
