Recent research indicates that only about half of perceived friendships are mutual. That is, someone you think is your friend might not be so keen on you. Or, vice versa, as when someone you feel you hardly know claims you as a bestie. It’s a startling finding that has prompted much discussion among psychologists, neuroscientists, organizational behavior experts, sociologists and philosophers. Some blame human beings’ basic optimism, if not egocentrism, for the disconnect between perceived and actual friendships. Others point to a misunderstanding of the very notion of friendship in an age when “friend” is used as a verb, and social inclusion and exclusion are as easy as a swipe or a tap on a smartphone screen. It’s a concern because the authenticity of one’s relationships has an enormous impact on one’s health and well-being. The study analyzed friendship ties among 84 subjects (ages 23 to 38) in a business management class by asking them to rank one another on a five-point continuum of closeness from “I don’t know this person” to “One of my best friends.” The feelings were mutual 53 percent of the time while the expectation of reciprocity was pegged at 94 percent. This is consistent with data from several other friendship studies conducted over the past decade, encompassing more than 92,000 subjects, in which the reciprocity rates ranged from 34 percent to 53 percent. http://www.nytimes.com/2016/08/07/opinion/sunday/do-your-friends-actually-like-you.html
One factor may be simply that people are unwilling to admit that they have few or even no friends when asked, so they pick somebody they are sort of ok with.
