The researchers – some of whom were Facebook employees at the time the research was carried out – analysed the emotional content of billions of updates posted to Facebook between January 2009 and March 2012.
To test whether emotions spread, they looked at how updates changed when it rained.
They found that negative Facebook posts increased by 1.16% and positive posts decreased by 1.19% in response to gloomy weather.
They then looked at the posts of people who were friends with those impacted by rain, but who lived in cities where the weather was not necessarily as bad.
The result? Every sad post generated an extra 1.29 more negative posts than normal among people’s friends.
