It seems intuitive to me. If you have a problem and then activists put in a ton of time to make that problem more visible, its going to change people's perceptions of social issues. For example, if you asked people in 1990 and 2020 if the Catholic church adequately protects children from sexual predators, you're probably gonna get a pretty drastic difference in responses.
