ChromeView: A Plugin Designed to Fight Selective Exposure

"Algorithm models and machine learning systems. Whether we realize it or not, our daily lives center around them," explained a team of Carnegie Mellon University undergraduate students in their paper for Jason Hong's Social Web course. From recommending additional purchases to trading stock on Wall Street, algorithms help us navigate the overwhelming amount of information and decisions in front of us. However, they may be more involved in our daily lives than people care to admit.

Kulkarni's research focuses on building technology that can support and improve how people live and learn. So he was quick to spot an opportunity following the election to connect groups of people with differing opinions for a positive gain.

"It is easy to say, 'I'm going to talk to somebody else and try to understand them,' but without the right circumstances, you're quickly at each other's throat," Kulkarni said.

Friends Help Friends Feel Better on Facebook

Personal interactions on Facebook can have a major impact on a person's feelings of well-being and satisfaction with life just as much as getting married or having a baby, a new study by Carnegie Mellon University and Facebook researchers shows.
