Acts of kindness and acts of novelty affect life satisfaction

J Soc Psychol. May-Jun 2010;150(3):235-7. doi: 10.1080/00224540903365554.


The present experiment was designed to establish the effects of acts of kindness and acts of novelty on life satisfaction. Participants aged 18-60 took part on a voluntary basis. They were randomly assigned to perform either acts of kindness, acts of novelty, or no acts on a daily basis for 10 days. Their life satisfaction was measured before and after the 10-day experiment. As expected, performing acts of kindness or acts of novelty resulted in an increase in life satisfaction.
