To fight fake news and "alternative facts," Google is highlighting other fact checking sources in rich snippets for certain queries. The example that SearchEngineLand gives is a result for Snopes, where the conclusion of the fact checking is shown below the link.
It seems pretty unintrusive and it also uses other sources, rather than Google putting their own fact checkers on the case. If they have those. Sounds like a fact-checking type site could stand to gain from something like this, because the snippets appear to link straight to the articles. SEL postulates that "fake fact checkers," could rise to take advantage of this as well. Google seems to be displaying conflicting conclusions when they're available, so folks are still free to draw their own conclusions with the information available.
