The existing literature provides evidence that public opinion and attitudes often affect public policy. However, little is known about how public policy might affect attitudes and norms. I present new evidence on this topic by using age-based health insurance policies in the United States as natural experiments. I first exploit the discrete drop in insurance coverage rates at age 26 due to the Affordable Care Act’s dependent coverage mandate and show that this policy is associated with statistically significant deterioration in attitudes towards the necessity of health insurance among young adults who are affected by this policy the most. Next, I show that gaining health insurance at 65 due to the onset of Medicare does not have a significant impact on attitudes towards health insurance among the elderly. These findings are widespread across different demographic groups, robust under alternative model specifications, and observed only after the policies are adopted.
