A new Wikipedia study suggests that when experts and non-experts look to
assess Wikipedia for accuracy, the non-experts are harder on the free
encyclopedia than the experts. The researcher had 55 graduate students and
research assistants examine one Wikipedia article apiece for accuracy,
some in fields they were familiar with and some not. Those in the expert
group ranked their articles as generally credible, higher than those
evaluated by the non-experts. One researcher said 'It may be the case that
non-experts are more cynical about information outside of their field and
the difference comes from a natural reaction to rate unfamiliar articles
as being less credible.'
