This is what happens when academic studies are not open access.
The video links to columns from Tommy Christopher at mediaite . Go ahead read these columns. In mediaite, Tommy Christopher examined this oft-cited 2001 study and I thought it was Anderson & Bushman (2001), but it turns out to be some open access paper written by David Bond (University of South Florida) in 2011 who happened to have a similar title to Anderson & Bushman (2001). I am upset that someone got the source wrong and went along without checking. In addition, a proper citation to the original sources (i.e. Ferguson & Kilburn, 2010) would have been great. For example, Christopher mentioned a review of 130 articles which was actually from Anderson et al. (2010) and not from the old 2001 article. Ferguson & Kilburn criticized the Anderson et al. 2010 article, so it would be have been great if these two were brought up.
