Are we all connected?
‘Six degrees of separation’ implies we are mere acquaintances away from knowing everyone on the planet, but how accurate is it? The small-world experiment (1967) involved dispatching randomly-addressed folders across the USA with instructions to pass it on to someone who could possibly aid in its delivery. While it took an average of six ‘links’, only 64 of 300 folders reached their destination, casting doubt on the premise. Despite this criticism, social media companies now have the data to support what the experiment sought to prove with one slight difference; instead of six degrees, they estimate it to be just four.
