 Good faith and newcomers
 "It is important to be patient with newcomers, who will be unfamiliar with Wikipedia's culture and rules, but may nonetheless turn out to be valuable contributors. "
 "Many new users who lack an intuitive grasp of Wikipedia customs are gradually brought around, once the logic behind these customs becomes clearer to them. "

+
+The Vandalism Studies project is a portion of the Counter-Vandalism Unit designated to conduct research related to unconstructive edits on Wikipedia.
+
+There are 3 Studies:
+Study 3 (suggest ideas) 	Discussion ongoing..., but planned for November
+Obama article study (talk page) 	☒ Stale
+Study 2 (talk page) 	☒ Not done and not likely to be done
+Study 1 (talk page) 	 Done
+
+====================================================================

+
+User:Angela conducted a vandalism study on her own user page.
+
+"Vandalism studies/Study1 found that almost all vandalism (97%) is made by unregistered users. Looking at vandalism on my own user page, I find a very different result. Almost half of the vandalism is made by registered users. "

+
+Another user conducted vandalism study.
+This one vandalises featured articles (different types of vandalism) and looks at the times to revert.
+
+========================================================================

+
+And yet another user conducted study.
+This one is "Loren Cobb (User:Aetheling) holds a Ph.D. in mathematical sociology and is a research professor in the Department of Mathematical and Statistical Sciences at the University of Colorado Denver."
+
+studies the survival function of vandalism
+
+The two primary results from this study are: (a) the median time to correction is down to four minutes, and (b) some subtle forms of vandalism still persist for months and even years.
+
+suggest using median rather than mean time to correction
+
+100 randomly selected articles
+"All data collection occurred on 2009-06-11"
+
+"
+Results
+    Of the 100 articles, fully 75 had never been vandalized.
+    Of the 25 articles that were vandalized at least once, the most recent such instance of vandalism was eventually corrected in 23 articles.
+    In five (20%) of the vandalized articles, the most recent instance of vandalism was corrected in less than one minute. A further four instances were corrected in less than two minutes.
+    The median time to correction was four minutes.
+    Two articles were found to have suffered vandalism that was never corrected. One of these was a subtle act of vandalism that was committed on 2007-02-23, and still not detected by the date of the study, 2009-06-11.

+Sources of vandalism
+
+Vandalism comes from:
+
+    Anonymous IP addresses
+    Newly registered users (typically vandal-only accounts)
+    Disruptive editors (limited but some constructive work)
+    Trolls, sock puppets, etc. - disgruntled "power users"
