1. A method comprising: storing reliability data that indicates, for each source of a plurality of sources, a reliability rating of said each source; wherein a first source of the plurality of sources has a first reliability rating that indicates a reliability of the first source, and a second source of the plurality of sources has a second reliability rating that indicates a reliability of the second source and that is different than the first reliability rating; wherein at least one of the first reliability rating or the second reliability rating is based on previous fact checking results; receiving information to be fact checked; selecting at least one of the first source or the second source from among the plurality of sources based on the first reliability rating or the second reliability rating, wherein a difference between the first reliability rating and the second reliability rating indicates that one source is more reliable than the other source; in response to receiving the information to be fact checked, performing a comparison of the information to be fact checked with source information from one or more sources to determine factual accuracy of the information and to generate a fact checking result representative of a factual accuracy of the information, the one or more sources comprising the at least one of the first source or the second source; causing an icon indicative of the fact checking result to be displayed; wherein the method is performed by one or more computing devices.
