A trio of social psychologists posited the propinquity effect (1950), noting humans are more likely to form relationships among those with whom they regularly interact. The psychologists then asked residents at a university to rate their friendships; the closer residents’ dorms were to each other, the more likely they were to be friends. Those located near stairwells or mailboxes were also significantly more likely to have friends on other floors. These results encourage us to engineer our own relationships, scheduling more time to share moments or simply the same air.
