Are you saying that there is not a negative correlation between increasing availability of porn and decreased murder and rape?
i’m saying that *any* correlation (negative or postive) would be suspect because of difficulty and out right bias that riddle the basic methodology and misuse of statistics in so called “social science.” if i were going to site such a study, i’d have to be confident of the integrity of the person conducting the study and the effort and skill made to stratify the sample.
so how did the study sample the use of porn amongst confirmed rapists and/or murderers? by interview.
did the study just take an average over the whole country for crime and invent some number for “availablity of porn?”
what i’m saying is that most of social science is junk science. the people undertaking such studies are looking to confirm their own apriori conclusions.
