Seems to me that the results of the article suggest that such a slider would help. But I wonder if it wouldn't lose its effect after a while as people get exposed to it and begin filtering it out, a la cigarette warning labels and cookie consent banners? Regardless, it seems like there's a lot of potential here for social media sites to make a significant and positive change without turning to stricter moderation which can in itself be problematic.
: Does anyone know if that's actually the case?
