If someone troubled has no access to mental healthcare and instead receives a steady stream of negative stimulus over long periods of time thanks to fb/youtube/twitter/news media's engagement algos, what do you think the result is? Think about it everytime a racists watches a racist vid/tweet/post/show/podcast on the side bar there is a endless buffet of further recommendations. All this reinforces whatever it is they believe.
The mental health resources available for the kind of reach social media and news media have does not exist. In most places there is one mental health professional per 20k citizens. This is not going to change overnight.
So what I am talking about is reducing the rate at which (negative/controversial) info recommendation systems/engagement algos pump through the system.
That's what I mean by time out. Reduce the rate at which info flows and the amount of info flowing through the system. This can be done in many ways. Turn off real time analytics to the content producers when they pump out controversial content. Hide/delay the like/view/click counts around polarizing content. Change or remove recommendations around such content etc etc...
