Gone are those days when you think that whatever you on internet with privacy settings on, it will keep all your secrets. A news that just broke out couple of days ago has spread as a fire in the forest. According to which “Facebook researchers held a controversial psychology experiment on users”.

Today, the researchers came up defending for what they have done in the name of research experiment. They track down the news feed of Facebook users in order to know about how they feel emotionally on Facebook. According to researchers they were also concerned that exposure to friends’ negativity might lead people to avoid visiting Facebook. “We didn’t clearly state our motivations in the paper,” researcher Adam D.I. Kramer wrote on his Facebook page Sunday.Facebook security

Researchers did their studies on 700,000 Facebook users. Moreover the researchers claim that the aim of the experiment was to find out if exposure to emotions led people to change their own posting behavior, and in which direction.

The results they concluded were not unexpected. The emotional states can be transferred to others via emotional contagion, resulting the readers to experience the same emotions and act accordingly.

Though this experiment has gathered a very negative response from most of the Facebook users, but many Facebook users still don’t know how Facebook is reading their interests through their feed and shows them ads according to them. This news has again raised questions on Facebook security and privacy for users, but it is very early to say that this community of over a billion people will go down anytime soon.
