A 2014 Pew Research Center survey found that 91% of Americans "agree" or "strongly agree" that people have lost control over how personal information is collected and used by all kinds of entities. Some 80% of social media users said they were concerned about advertisers and businesses accessing the data they share on social media platforms, and 64% said the government should do more to regulate advertisers.
Studies have shown that self comparison on social media can have dire effects on physical and mental health because they give us the ability to seek approval and compare ourselves. Social media has both a practical usage- to connect us with others, but also can lead to fulfillment of gratification. In fact, one study suggests that because a critical aspect of social networking sites involve spending hours, if not months customizing a personal profile, and encourage a sort of social currency based on likes, followers and comments- they provide a forum for persistent "appearance conversations". These appearance centered conversations that forums like Facebook, Instagram among others provide can lead to feelings of disappointment in looks and personality when not enough likes or comments are achieved. In addition, social media use can lead to detrimental physical health effects. A large body of literature associates body image and disordered eating with social networking platforms. Specifically, literature suggests that social media can breed a negative feedback loop of viewing and uploading photos, self comparison, feelings of disappointment when perceived social success is not achieved, and disordered body perception. In fact, one study shows that the microblogging platform, Pinterest is directly associated with disordered dieting behavior, indicating that for those who frequently look at exercise or dieting "pins" there is a greater chance that they will engage in extreme weight-loss and dieting behavior.
Observers have noted a range of positive and negative impacts of social media use. Social media can help to improve an individual's sense of connectedness with real or online communities, and can be an effective communication (or marketing) tool for corporations, entrepreneurs, nonprofit organizations, advocacy groups, political parties, and governments. At the same time, concerns have been raised about possible links between heavy social media use and depression, and even the issues of cyberbullying, online harassment and "trolling". Currently, about half of young adults have been cyberbullied, and of those, 20% said that they have been cyberbullied regularly. Another survey in the U.S. applied the Precaution Process Adoption Model to cyberbullying on Facebook among 7th grade students. According to this study, 69% of 7th grade students claim to have experienced cyberbullying, and they also said that it was worse than face-to-face bullying. Both the bully and the victim are negatively affected, and the intensity, duration, and frequency of bullying are the three aspects that increase the negative effects on both of them.
