Overview

Online pornography is a significant but underexamined vector of harm for adolescent boys. Unlike social media, which harms girls primarily through social comparison, pornography harms boys by hijacking the evolved sex drive during the sensitive period in which the brain’s sexual and relational circuitry is being configured. The ready availability of free, high-quality, extremely varied pornographic video — accessible in private on personal devices — creates risks of compulsive use, desensitisation, and interference with real-world romantic and sexual development.

Prevalence and gender asymmetry

Mechanisms of harm

Pornography exploits the evolved sex drive by separating the lure (sexual pleasure) from its real-world reward (an actual sexual relationship):

Contrast with printed pornography

Before the internet, access to pornography was low-quality (printed magazines), not sold to minors, and functioned partly as a motivator pushing boys toward the real-world social risks of dating. High-speed internet reversed this: infinite variety, high quality, free, private, always available. The sex drive that was meant to push boys toward social risk-taking is now easily satisfied in isolation.

Generative AI and the coming intensification

Haidt warns that the harms from pornography are likely to intensify with the metaverse, spatial video, and generative AI, which can produce three-dimensional pornography featuring “perfect” synthetic people. AI-powered virtual companions (e.g., CarynAI) already demonstrate that many users form genuine emotional attachments to chatbots. As these systems improve and are embedded in physical sex dolls, heterosexual men may increasingly prefer a hikikomori lifestyle with a programmable companion over the social risk of real-world dating.
