SGB I have a hard copy of a Ministry of Justice study, conducted in September 2007, entitled:
"The evidence of harm to adults relating to exposure to extreme pornographic material: a rapid evidence assessment (REA)"
Sorry, no time today, to see if this is on the web, but imagine it would be?
Another study worth reading is the Home Office commissioned "Review into sexualisation of young people" published in February of this year.
In terms of reading, "Social problems and the quality of life (11th ed.)" Lauer, R.H., & Lauer, J.C. (2008) is a good read and one that might appeal to you, since the authors are libertarians and it can be quite difficult to find academic research on this subject, that doesn't have a religious/right-wing slant. Pamela Paul's book "Pornified" is also an interesting read.
I am also excited about some new thinking and partnership working that is taking place between secondary schools and policing and social care agencies, about the links between assailants' porn use and an increase in sexual attacks on girls by male students. There has been anecdotal evidence for years that there is a link between the increased violence in such attacks and prior exposure to violent porn, but new projects are being set up to investigate the link, using the assailants' testimonies about their porn use, prior to the attack.
Part of my work also involves liaison with senior police officers involved in the investigation of serious gang-related violence. It is pretty well-documented now that many of the worst gangs have a young female whose membership is entirely reliant on her being shared by gang members for sex. If she is seen talking to a rival gang member, retribution from her masters is brutal and swift. Many of these young girls are care-home absconders and the most vulnerable in society. To a person, these police officers have found evidence of extreme porn in personal and house searches; memory sticks and laptops being the main evidential source. Those police officers are in no doubt about the link between porn and the gang members' treatment of females.
However, for all the academic studies and the acknowledged scientific and academic challenge of proving cause and effect, our lived experiences and those of others, represent our most powerful discourses.
This forum is a pretty good barometer of what is happening in the UK especially and it would be absurd to deny that we see thread after thread about the corrosive effect of porn on relationships. People's lived experience is a powerful testimony and many posters have been brave enough to discuss them on this thread alone.
Calling people "whiny arses" or "bucketheads" for expressing a perfectly valid dissent to having porn in their lives is offensive and seems bullying in nature. You are entitled to your views, but so are others and they should be free to do so without fear of being called names.
