Wisdom of crowds, knowledge, wikipedia vs brittanica, what the hell?

If the wisdom of crowds confirms that the group is more intelligent than the expert, then this result is unexpected.  A close result is interesting, but does not prove the premise.

The experiment "sent 50 pairs of Wikipedia and Britannica articles on scientific topics to recognised experts and, without telling them which article came from which source, asked them to count the numbers of errors (mistakes, misleading statements or omissions). Among the 42 replies, Britannica content had an average of just under 3 errors per article whilst Wikipedia had an average of just under 4 errors
