No that's of girls who have thoughts of suicide, 13.5% say it makes it worse. Ok, is that good or bad? The number is meaningless without a control.
Are you sure? Do you have the study? Iirc the sample was extremely small. It's unlikely that they had a large enough subset of suicidal girls.
If Facebook made money doing something they knew there was a non-zero risk of pushing even one person to suicide, they are a sociopathic organization.
And then you could say, well, maybe some of those places didn't do the research. In which case, isn't that worse? If they are making people more suicidal and they don't even care enough to research and find out, how are they possibly going to get better? I would much rather an institution research the harms (and benefits) that it may be causing than to just turn a blind eye.
