How Does Your Facebook News Feed Affect You?

by Jalees Rehman in The Next Regeneration

Researchers at Facebook, Inc., the University of California, San Francisco (UCSF) and Cornell University teamed up to study whether manipulating the News Feeds of Facebook users would affect the emotional content of the users' status updates or postings. They recently published their findings in the PNAS paper "Experimental evidence of massive-scale emotional contagion through social networks" and suggest that they have found evidence of an "emotional contagion", i.e. the idea that emotions can spread via Facebook....

Sharing Our Sorrow Via Facebook

by Jalees Rehman in Fragments of Truth

Geteiltes Leid ist halbes Leid ("Shared sorrow is half the sorrow") is a popular German proverb which refers to the importance of sharing bad news and troubling experiences with others. The therapeutic process of sharing takes on many different forms: we may take comfort in the fact that others have experienced similar forms of sorrow, we are often reassured by the empathy and encouragement we receive from friends, and even the mere process of narrating the details of what is troubling us can be beneficial. Finding an attentive audience that is willing to listen to our troubles is not always easy. In a highly mobile, globalized world, some of our best friends may be located thousands of kilometers away, unable to meet face-to-face. The omnipresence of social media networks may provide a solution. We are now able to stay in touch with hundreds of friends and family members, and commiserate with them. But are people as receptive to sorrow shared via Facebook as they are in face-to-face contacts?
