Brief interactions with strangers causally boost happiness, study finds

By PulseAugur Editorial · [1 sources] ·

A recent study published in Social Psychological and Personality Science, using large samples and an instrumental-variable approach, found that brief, positive interactions with strangers, such as a simple thank you, can causally increase an individual's reported life satisfaction. This finding challenges the assumption that happiness is solely derived from close relationships, suggesting that these "weak ties" provide a measurable boost to well-being. Further research in the Journal of Happiness Studies indicates that these minimal interactions act as a supplementary source of happiness, particularly on days when close relationships are less responsive, offering a readily accessible tool for enhancing daily mood.
