"The best external research indicates that Facebook's impact on people's well-being* is negative. FB can have a negative effect when people feel a lack of control over the experience or when use undermines other aspects of life." "We've identified 3 drivers that might be contributing to negative well-being**: Problematic Use, Loneliness, and Social Comparison" "Problematic use affects about 12.5% of people on Facebook." "People perceive the impact. In a comparative survey with competitors, people perceived lower well-being and higher problematic use on Facebook compared to any other service. (Twitter, YouTube, IG, WA, Snapchat, Reddit, World of Warcraft)" "Loss of productivity - (1) Giving up. The person won't do the task/ activity outside FB. (2) Postponing the beginning. The person will take more time to start the task/ activity off FB. (3) Extending the duration. The person will take more time to complete the task because will stop to check FB. Sleep disruption – (1) Delaying/reducing sleep hours due to loss of time control; (2) Waking up and checking FB prolonging a return to sleep; and (3) Sleep loss due to disturbing content, like politics or violence. Relationship impacts - People together but separately on their phones. And a false sense of closeness created by seeing updates on FB, but fewer offline visits. Parents neglecting their kids – Parents focused more on FB than caring for or bonding with their children. Or refrained from reprimanding kids for risk of later "retaliation" on their own use. Safety risks – Loss of situational awareness around environmental dangers (moving vehicles, pickpockets). Regretful purchases – Spending money on things they didn't need."
