Researchers call sharing good news with another person capitalization.
A daily-diary study involving 90 couples found that on days people perceived their partner's response to their good news as active and constructive, they reported a stronger sense of couple identity.
In other words, enthusiastically celebrating a partner's success may do more than make them happy.
It can reinforce the feeling that both people belong to the same team.
Relationships aren't strengthened only by helping each other through bad moments.
How you react when things go right can matter too.
