Social Networking is not inherently toxic, and quitting many things: sugar, television, even meat, might have the similar effects for some small group of people.
In fact, the entire thread is based on three levels of indirection of misinformation: the Bloomberg article misquoted the paper, and the short-summary referencing Bloomberg made it worse.
Here is the summary of the findings [1]:
"We find that deactivating Facebook for the four weeks before the 2018 US midterm election (i) reduced online activity while increasing offline activities such as watching TV alone and socializing with family and friends; (ii) reduced both factual news knowledge and political polarization; (iii) increased subjective well-being; and (iv) caused a large persistent reduction in post-experiment Facebook use"
So that's a little bit more information now isn't it? And completely conflates the Facebook/wellbeing issue with a host of other things.
Most poignantly, stopping Facebook usage reduced the amount of factual knowledge a person had access too. So maybe that's not so good?
Maybe by 'removing Facebook' people are simply a little bit more removed from the issues of the day (like elections) many of which can be contentious.
So 'ignorance is bliss' is the result of the study? Or is it really something materially related to Social Networking.
I think we'll need to do some more studying to find out.
How can we distinguish the effect from a general “I’m making a change” groundswell of feel goodery?
Picking up moderate drinking isn't going to make you healthier / more successful.
It's just that successful people tend to be healthier and also are more likely to have a healthy relationship with alcohol.
