By comparison, the R-squared effect size for media violence—including television—ranges anywhere from one percent to nine percent.
Some researchers have described what they call “instructive parallels” between the relationship of media violence to youth aggression and the relationship of smoking to lung cancer.13 By using meta-analyses that pool the results of many different studies (more on that later), they conclude that the effect size (the strength of the relationship) of the violent media-aggression link is almost as big as the smoking-lung cancer link.
For example, twin studies of antisocial or violent behavior find that about 50% of the variation the R-squared effect size is due to genetics.
It’s hard to know because, aside from the Stroebes’ review of who suffers more, nobody has done a meta-analysis to determine the average effect size of studies on how long women and men take to grieve.
