Google currently ranks sites on their incoming links. The company is now developing a new ranking software that would access Google’s Knowledge Vault, which compiles facts that are virtually unanimous in upholding as true. So Google “vaccines and autism,” and you would more likely get a first paging touting peer-reviewed science rather than the unfounded speculations of celebrities.
This strikes us as a necessary but risky venture into the slippery world of what’s true and what’s not.
