It is no surprise that social
interactions can be a great source of happiness. A wonderful holiday spent with close friends
and family is not only enjoyable in the moment, it is also a source of
wonderful memories for years to come.
Being in a great romantic relationship is uplifting.
But, what about the large number
of other interactions you have each day?
The cashier at the supermarket who smiles and tells you to have a great
day. The colleague you pass in the hall
who nods as you walk by. The friend of a
friend you chat with for a minute about a recent TV show. Do those interactions also make you happier?
In the 1970’s, sociologist Mark
Granovetter has looked at the structure of people’s social networks. This work suggests that you can loosely characterize
people’s contacts into strong ties
and weak ties. Strong ties are the bonds among family,
friends, and close work colleagues. Weak
ties are involve the people you see on occasion. You do not have particularly deep or regular
contact with your weak ties.
Research in business suggests
that weak ties are extremely important for passing information across
groups. For example, a company may have
lots of pockets of people who work closely together. The members of this group share information
extensively. That information can only
flow from one group to another through weak ties where one member of the group
shares it with someone who is primarily connected to a different group within
the company.
What about happiness? Can weak ties contribute to your happiness?
This question was explored in a
paper by Gillian Sandstrom and Elizabeth Dunn in the July, 2014 issue of Personality and Social Psychology Bulletin.
In one study, 53 adults over the
age of 25 were given two clickers. On 6
different days, participants counted the number of people they interacted with
that day using the clickers. They used
one clicker for people with whom they had a close relationship (strong ties)
and the other for people with whom they had a more distant relationship (weak
ties). On each day, participants also
rated their well-being and their sense of belonging to a community. Participants also filled out a personality
inventory, because basic personality characteristics are also related to
people’s well-being. All of the analyses
were done ensuring that the results could not just be predicted from the basic
personality characteristics.
On average, people interacted
with 6.7 strong ties and 11.4 weak ties in a day. One way you might think to analyze these data
is to see whether the number of interactions predicts happiness overall. Interestingly, differences in happiness between
people are not that strongly predicted by the overall number of interactions
they have.
However, the number of
interactions people have does predict day-to-day differences in sense of
belonging and happiness. Strong ties are
particularly important. On days when
people interact many times their strong ties, they report that they are happier
and feel more like they belong to the community than when they interact fewer
times with their strong ties. In this
sample, interactions with weak ties predicted people’s sense of belongingness,
but only weakly predicted happiness.
That is, more interactions with acquaintances increased people’s sense
that they belonged to a community, but had only a weak relationship to their
overall happiness.
A second study with the same
method examined 58 first-year college students.
They also kept track of their interactions using clickers. You might expect the results with this group
to be stronger, because first-year college students are just starting to form a
new set of relationships.
In this study, the number of
interactions with both strong and weak ties was related to the students’ sense
of belongingness overall. So, those
students who interacted with a lot of people were happier and felt a greater
sense that they belonged to the college community than those who interacted
with only few people.
In addition, on days when people
interacted with both their close friends and their acquaintances, they were
happier than on days when they interacted less often with their close friends
and their acquaintances.
What does all of this mean?
The interactions we have with
other people affect the way we feel about life.
Our close relationships keep us grounded and influence both happiness
and the sense that we are part of a larger community. Interestingly, even our interactions with
people we do not know that well give us a sense that we are part of that larger
community. When we are first introduced
to that community, those interactions and that feeling of belonging also
increase our happiness.
So, smile at people when you walk
down the street. You just might be
helping to make someone’s day.
