Who Responds to What Incentives? Part II

Why do people visit pornography sites on the internet? Is it curiosity? by accident? for prurient interest? Unfortunately these data do not tell us the motives of these people or the incentives they face.

• 51% of pastors say cyber porn is a possible temptation. 37% say it is a current struggle (Christianity Today, Leadership Survey, December 2001). 4 in 10 pastors have visited a porn site (Christianity Today, Leadership Survey, December 2001).
• 17.8% of all "born again" Christian adults in America have visited sexually-oriented Websites (Zogby survey conducted for Focus on the Family, 2000).
