Human editorial parameters can move a ranking either up or down, according to the editorial opinion patent [patft.uspto.gov].

[Description]...An editorial opinion parameter for a favored source may, for example, cause the score of the associated web page to be upgraded by a percentage of its previous score or by an absolute value. Similarly, for non-favored sources, the applicable editorial opinion parameter may cause the score of the associated web page to be downgraded by a percentage of its previous score or an absolute value.
