They Know What You Did Last Summer
According to a recent study published by the Pew Research Center, Americans are painfully aware of what social networks know about them. The vast majority of adult users think that it would be easy for social media companies to figure out their race/ethnicity, hobbies and interests, political affiliation and religious beliefs based solely on the information they shared on their site.
Seeking to be transparent about its data collection, Facebook offers its users the option to check their ad preferences, giving them a broad idea of the amount of information it has on them. When confronted with their personal ad preferences page, 74 percent of Facebook users surveyed by Pew said they were previously unaware that such a list existed, and 51 percent stated they weren’t comfortable with Facebook collecting this data.
This chart shows how many Americans think it would be easy for social media companies to figure out certain things about them based on the information they share on social networks.
