Ms. Flora did note the advantages of digital media for introverts and people susceptible to loneliness, namely that it is less risky and enervating to make contact through a text or post than through a phone call or an invitation to meet.
When I was in high school I bought my first cell phone, and it came with a truly amazing feature: Text messaging. I remember how amazing it was to be able to communicate with anyone without actually talking to them!
Things got even better when I got access to the world wide web on my spare time. I found a chat room with some friendly people, bound together by a common interest in video games and pop culture, which I still hang out in every day, almost a decade later. Without that room and those dozen+ people I count among my friends, spread across time zones, I might have been a very lonely person.
These findings jibe with the research of Robin Dunbar, a professor of evolutionary psychology at Oxford. He has theorized that “group size” of both humans and nonhuman primates — the number of people (or, say, chimpanzees) one can maintain social cohesion with — correlates to “relative neocortical volume,” or the ratio of the neocortex to the rest of the brain.
