He might have a trait that conflicts with others. Like teetotaler vs chemical interest. Not much you can do there.
Check their relationships, if there is no fixed relationship malus, try giving him and some other, compatible people some dedicated joy time, and put all of the beer and joy stuff in one room so they will talk each day while having their scheduled break.
Also check for any facial injuries. I heard that someone with a messed up face or missing ears etc. gets a social interaction penalty, so maybe try and fix that somehow before sending your people to make out with one another xD
