this is generally limited to things that wikipedia editors of vastly opposing viewpoints can agree on, like whether and when the restaurant was awarded a michelin star

like, imagine a vegan, a devout hindu, a muslim, a carnivore, a neighborhood kid, and a foodie editing an article about a texas steakhouse that is known for its barbecued pork. whatever text any of these people finds unfairly biased is going to get deleted from the article, and what's left is what they can agree on

this process produces astoundingly reliable articles on contentious topics like the armenian genocide, but the results are predictably of poor literary quality, and generally not very useful for things like guessing which restaurant you would prefer to eat at
