Laura Fitton has an insight that might change your mind. She points to the idea of reciprocity.
“A study in the 1970’s took two strangers and one was in a situation of peril,” she says. “They waited to see if the other one would intervene. Then they ran it again, but the two strangers passed in the hallway first and simply said, “Hello.” That tiny, tiny bit of interaction dramatically increased the reciprocity.”
She concludes that even random trivial interactions that people are having on social networks turn out to contribute to longer term value.
So when you find yourself asking why do I care what that person had for breakfast, consider that maybe you don’t, but possibly the interaction itself is more valuable than the information.
