"Starting in 2018, there was growing concern in the public... that technology companies were deliberately manipulating users by designing addictive products that can harm well-being and subvert control, labeling these concerns 'Facebook Addiction'...

"Starting in 2018, there was growing concern in the public (amongst media, academics, policy elites, and everyday users) that technology companies were deliberately manipulating users by designing addictive products that can harm well-being and subvert control, labeling these concerns 'Facebook Addiction'. Efforts were spun up across Facebook and Instagram to more deeply understand these concerns. Initial products were launched to give people more control over their use, though efforts were defunded end of 2019 with additional opportunities still available." "We internally aligned on 'Problematic Use' (PU) as a more accurate term to describe habitual or undesired use of Facebook." "A person is classified as experiencing problematic use through self-reported survey measures. Internally, we define problematic use as experiencing both of the following issues either 'very often' or 'all the time': Lack of control or feelings of guilt over Facebook use. Negative impact in at least one of the following areas: sleep, parenting, social relationships, or productivity." "12.5% of people worldwide experience problematic use." "Triggers for Problematic Use on Facebook" "Notifications - Getting too many minor/irrelevant notifications. Try to only look at important ones but get sucked into longer sessions." "Mystery of the algorithm - Uncertainty over if they will see posts from those they want; if they can find a post again later." "Videos - Easy to get immersed (especially before bedtime). Auto-play exacerbates the issue." "Fear of missing out (FOMO) - Worry about missing important world news or updates in their social circles." "Groups - Get exponentially more notifications, engaged in chat threads."
