Being kind is more than just a display of good manners. A 2018 study published in The Journal of Social Psychology demonstrates that being kind to others, whether or not we are close to them, may be inherently rewarding for us and activate an evolved neuro-biological system involved in caring for others. Furthermore, observing kindness—rather than seeing a world full of stress and bad news— is a way of noticing the good around us, which can boost our mood.
