Public service announcements that claim to be about "preventing teen pregnancy" are more frequently about shaming and stigmatizing young parents. This is not a way to encourage young people to take control of their reproductive lives, and it's certainly not a way to support young families.
Beyond that, once we control for social factors such as socioeconomic class, most of the adverse outcomes claimed in these ads disappear. Not only are these ads shaming, then, they're misinforming.
