A 2007 study by researchers from [[Dartmouth College]] found that "anonymous and infrequent contributors to Wikipedia&nbsp;... are as reliable a source of knowledge as those contributors who register with the site".<ref name="sciam good samaritans 1">{{cite news |url=https://www.sciam.com/article.cfm?id=good-samaritans-are-on-the-money |title = Wikipedia "Good Samaritans" Are on the Money |work = Scientific American |date = October 19, 2007 |access-date = December 26, 2008}}</ref> Jimmy Wales stated in 2009 that "[I]t turns out over 50% of all the edits are done by just .7% of the users{{nbsp}}... 524 people{{nbsp}}... And in fact, the most active 2%, which is 1400 people, have done 73.4% of all the edits."<ref name="blodget" /> However, ''[[Business Insider]]'' editor and journalist [[Henry Blodget]] showed in 2009 that in a random sample of articles, most Wikipedia content (measured by the amount of contributed text that survives to the latest sampled edit) is created by "outsiders", while most editing and formatting is done by "insiders".<ref name="blodget" />

A 2008 study found that Wikipedians were less agreeable, open, and conscientious than others,<ref name="liebertonline view on WP users 1">{{cite journal | last1 = Amichai-Hamburger | first1 = Yair | last2 = Lamdan | first2 = Naama | last3 = Madiel | first3 = Rinat | last4 = Hayat | first4 = Tsahi | year = 2008| title = Personality Characteristics of Wikipedia Members | journal = CyberPsychology & Behavior | volume = 11 | issue = 6| pages = 679–681 | doi = 10.1089/cpb.2007.0225 | pmid = 18954273 }}</ref><ref name="newscientist view on WP users 1">{{cite web |url=https://www.newscientist.com/article/mg20126883.900-wikipedians-are-closed-and-disagreeable.html |title = Wikipedians are 'closed' and 'disagreeable' |website = New Scientist |access-date = July 13, 2010}} {{subscription required|s}}</ref> although a later commentary pointed out serious flaws, including that the data showed higher openness and that the differences with the control group and the samples were small.<ref>{{cite web |url=https://www.psychologytoday.com/blog/unique-everybody-else/201303/the-misunderstood-personality-profile-wikipedia-members |title = The Misunderstood Personality Profile of Wikipedia Members |website = psychologytoday.com |access-date = June 5, 2016}}</ref> According to a 2009 study, there is "evidence of growing resistance from the Wikipedia community to new content".<ref name="newscientist WP boom to bust 1">{{cite web |last = Giles |first = Jim |title = After the boom, is Wikipedia heading for bust? |url=https://www.newscientist.com/article/dn17554-after-the-boom-is-wikipedia-heading-for-bust.html |website = New Scientist |date = August 4, 2009}}</ref>
