"And then there are the video games."
Whoa. Ease up.

Controversies over video games center on controversial content of video games
and effects that video games have on behavior.
Video games have been studied for links to addiction and aggression. Before
this[when?] meta-analyses were conflicting. A 2001 study found that exposure to
violent video games correlates with at least a temporary increase in aggression.
A decrease in prosocial behavior (caring about the welfare and rights of others)
was also noted. Another 2001 meta-analysis using similar methods and a
more recent 2009 study focusing specifically on serious aggressive behavior
concluded that video game violence is not related to serious aggressive behav-
ior in real life. Many potential positive effects have been proposed. Recent
research has suggested that some violent video games may actually have a pro-
social effect in some contexts, for example, team play.
It has been argued[by whom?] there is generally a lack of quality studies
which can be relied upon and that the video game industry has become an easy
target for the media to blame for many modern day problems.[ The most
recent large scale meta-analysis, examining 130 studies with over 130,000 sub-
jects worldwide, concluded that exposure to violent video games causes both
short term and long term aggression in players and decreases empathy and pro-
social behavior. However, this meta-analysis was severely criticized in the
same issue of the same journal for a number of methodological flaws, including
failure to distinguish clinically valid from unstandardized aggression measures
and for failing to solicit studies from researchers who have questioned whether
causal links exist, thus biasing the sample of included studies.
