A recent article in Slate makes the statistical argument that Internet porn may be correlated with a decrease in rates for the violent crime of rape. One interesting critique of the study discusses some of the data that the study neglected to interpret, suggesting that the data need not imply a benefit from porn, but may be consistent with a shift toward rape that is less likely to be reported (e.g., with acquaintances as victims rather than strangers).
In any case, to live the best life you can, stay away from porn of any kind and live high moral standards.
One more tip: stay away from creeps obsessed with sex. (Get them out of your community now by sending them to Washington – one of the benefits of our democratic process.)
Hat tips to Walter Reade and Mike Parker.
