If you printed every article ever written about loneliness, you would probably need a whole room full of file cabinets to house them. Maybe several rooms. Loneliness research seems to be its own industry.
Most of the research focuses on you. What is it about you that is making you lonely? Are you taking the right steps to excise your loneliness?
Now, an entirely different approach is becoming popular. It is about the architecture and design of happiness and sociability. By this way of thinking, the ways our dorms and houses and cities and towns are designed may well have a lot to do with how successful we are at forming meaningful connections with other people.
