I clearly don't agree with her, but I do find it ironic that....
The studies she quotes are under strict allegation of just being wrong based on lack of actual scientific study, bad control conditions, improper conclusions, etc. But any study not supporting a strong correlation is seen as perfect.
I'm just saying! Don't shoot the messenger.
I don't firmly believe there is at all any real evidence supporting it, but we can't just call every study we don't agree with bullshit. It just means that if there are studies going both ways, then more studies need to be done and those studies need to be under strict scientific scrutiny from both sides.
As an example, the psychology scientific community does believe there is a strong correlation between TV violence and violence in real life. After years of studies they do believe as a whole that TV violence can increase the likelihood of someone becoming violent or more violent in the right conditions. At least that is the way it's understood in developmental psychology through the process of vicarious learning (as I understand it, I'm not a psychologist but I have read quite a few books and attended lectures on the subject). With the understanding that there is a correlation(not causal, corollary) between violence on television and movies and violence in real life, then it should not be hard to believe there is could be a correlation between the two of indeterminate mathematical strength (at this point).
I recall a previous hot news item from a scientific study (not related to this one) saying that high protein diets increase you cancer risk as much as smoking. Everyone is all over it and all these people believe it. Only, the journal Cell Metabolism actually silenced some of the dissenting scientific opinion based on how the study was conducted, how the results were interpreted, etc. The members of that scientific community wanted to give their opinion on the study and results and were told by the editors to "put their opinions in the comment section on the website". In the end, the scientific community cannot silence it's bias's anymore than any human can. Which is why peer review is important and both sides of the debate considered carefully.
