Subjective well-being and social networks: human relationships are consistently found to be the most important correlation with human happiness. Happier people tend to have good relations with family and friends, as said by Diener and Biswas-Diener, who also add that “We don’t just need relationships, we need close ones” that involve understanding and caring.
Studies, including the one published on the British Medical Journal, reported that happiness in social networks may spread from person to person. Quoting its conclusions: “While there are many determinants of happiness, whether an individual is happy also depends on whether others in the individual’s social network are happy. Happy people tend to be located in the centre of their local social networks and in large clusters of other happy people. The happiness of an individual is associated with the happiness of people up to three degrees removed in the social network”.
