The findings also indicate that, even in the digital age, humans still form friendships based on personal interactions, said Tommy Nguyen, Rensselaer graduate student and member of SCNARC, according to a Rensselaer statement.
"Even though, thanks to the Internet, you can be friends with anyone on the planet, the likelihood that a person will be friends with someone in a distant location chosen at random is far lower than the likelihood that this person will be friends with someone who lives in close proximity," said Nguyen.
