I had access to all of this type of research when I was a public defender, but I haven't been a PD in years. I would suggest going to your local university library and looking it up there as access to most of these studies will require expensive journal subscriptions. For your second question: there is a fair amount of research into the effects of visual and audiovisual stimuli on pedophiles and other sex offenders.…
>For your second question: there is a fair amount of research into the effects of visual and audiovisual stimuli on pedophiles and other sex offenders. I'm more just curious because I haven't seen anything (other than from the authors I've cited) on the effects of fictional (and in particular highly stylized) material on regular people, or even pedophiles specifically. Gary Young's book on The Gamer's Dilemma from 20…
In relation to risk of re-offense (aka recidivism), access to stimulating images was found to increase the risk of recidivism dramatically, by double-digit %, and pedophiles are already one of the groups with the highest rates of recidivism (in this context, we're talking more than 50% rate of re-offending).
If you get off to sexually abusing a child, that is pedophilia, so essentially all CSA crimes are committed by pedophiles. Generally the only exceptions I can think of are where both of the "offenders" are teens engaged in consensual acts before they are old enough to legally consent.
To put it another way: access to regular porn may inflame the desires of a rapist, and they may even make him more likely to committ an offence; is this sufficient to illegalize porn for everybody? Alcohol may have the same effect, and the question still applies.
This hasn't been shown to be true. But more importantly, the converse has been shown to be true: the overwhelming majority of people can watch porn, or drink alcohol, without becoming rapists, so it is not the porn or alcohol that creates the urge to rape. In contrast, the consumption of CP has been shown to create the urge to engage in pedophilic acts in pedophiles. (Additionally, CP is also illegal because it results in actual physical harm to the child.)
Again, AFAIK nobody has done a study specifically on manga, since that's an incredibly niche market in the U.S. Studies using fictional characters in the U.S. have generally used Disney characters or similar, so if you really insist on following up on this, you should start your search with that.
