What happened in this episode?
Bill Maher and psychiatrist Dr Daniel Amen discuss two contentious health topics: early exposure to online pornography and perceived risks around childhood vaccination. Amen argues that internet access has changed childhood sexual development by giving very young children access to highly stimulating sexual content, which he says can hijack dopamine-driven reward pathways, particularly for children with genetic vulnerability to addiction. Both men blame weak parental supervision and device controls, and they reference age restrictions on social media in other countries as a model for limiting what children can access.
The conversation then pivots to youth mental health, with Amen claiming suicide among young people has risen sharply compared with their school years. He links a broad rise in childhood and adult conditions—such as diabetes, asthma, obesity, allergies and gastrointestinal disorders—to changing environments, and raises the increase in autism diagnoses. Amen says diagnostic criteria changes explain some of the increase and suggests a “gene-environmental toxin interaction” may also play a role.
On vaccines, Maher and Amen both frame a ‘middle’ position: they say vaccines are generally safe and beneficial, but argue there can be side-effects. Amen says it is probably not the case that vaccines broadly cause autism, while also suggesting a very rare triggering effect could exist for an extremely small subset. He also says he has seen brain scans he characterises as showing vaccine-related damage, while stressing such cases are not typical.
