Internet filtering and adolescent exposure to sexual material
Przybylski and Nash analysed caregiver-child data from 13,176 participants across the European Union and Turkey, then conducted a preregistered study with 1,004 British 14- and 15-year-olds and their caregivers. They tested whether household Internet filters were associated with less reported exposure to online sexual material.
The European exploratory analysis found small associations. Depending on the material, between 17 and 77 households would need filtering to be associated with one fewer adolescent encounter over a year. Filtering explained less than 0.5 percent of variation in exposure. The more rigorous British study found no protective effect.
This observational evidence does not show that every device-level control fails in every household. It does show that filtering’s intuitive appeal is not evidence of practical effectiveness. The authors call for randomised trials that count financial, informational, and human-rights costs, including overblocking of health and identity resources.
