Can change one's mood through social networks.

NetEase Science and technology news June 30, according to the U.S. National Academy of Sciences, the latest published papers, http://www.aliyun.com/zixun/aggregation/1560.html "> Facebook has come to the conclusion that "face-to-face interaction and nonverbal behavior is not an absolute necessity for emotional contagion" by scientifically changing the way users read new content. "That means you can change a person's mood through social networking," he said.

Number of 100,000 Facebook users became part of the psychological experiment under the data scientists ' arrangement. The experiment aims to understand how positive and negative effects are spread through social networks. The researchers selected 689,003 native-speaking Facebook users to try to remove the negative news they could read and to give more negative results to the other group. According to the academy, "when a user loads new and emotional content posts, each emotional post is deleted based on the user's ID of 10% to 90%." "Of course these posts can still be seen through the timeline or overload of a direct visit to a friend." The researchers also noted that they did not change any direct information sent between users.

As the researchers point out, this data manipulation has been written into Facebook's terms of use. When users register for Facebook, they agree that their information may be used for "internal operations, including troubleshooting, data analysis, testing, research, and service improvement." "While there is no explicit mention of new things in the terms of use, Facebook's experiments did not go beyond the scope of the terms of use." (John)
