Moods spread like ripples on the water

Findings in a new study show that moods -good and bad- spread across networks of social connections like ripples on water.

Specifically, the study found that a happy friend increased the odds of someone being happy by 15 per cent – but that a friend of a friend boosted the chance by about 10 per cent, and a friend of a friend of a friend by about six per cent.

Last year the same research team, in another study , also found that a person’s risk of gaining weight increased significantly when friends gained weight. If their friends gained weight a similar but lesser effect was evident on the individual.
