 The majority of the encyclopedia is written by male editors, leading to a gender bias in coverage; it also has a racial bias.An ideological bias on Wikipedia has been identified on both conscious and subconscious levels among editors.A series of studies from Harvard Business School in 2012 and 2014 found Wikipedia "significantly more biased" than "Encyclopædia Britannica" but attributed the finding more to the length of the online encyclopedia as opposed to partisan editing.
