Research says that witnessing simple acts of everyday kindness, such as one person giving up a seat on the bus, holding a door open for another, or helping someone pick something that dropped to the floor can promote altruism. This pychological phenomenon that makes us feel great, lifts our emotions and motivates us to do good is called elevation. Witnessing an uplifiting act inspires us to do the same for others. In essence, kindness is contagious.
