The holidays are a time for gathering with friends and family. For dudes; not so much. A study published by the American Sociological Review found that white, heterosexual men have the fewest friends of any American demographic – which may be why the 'bro-mance' movies like I Love You, Man hit so close to home. Lisa Wade is professor of sociology at Occidental College and principal writer for Sociological Images. She wrote about the American man’s friend crisis for Salon.
