What is it, exactly, that makes us kind? Why are some of us kinder than others and what stops us from being kinder? The Kindness Test, a major new study involving more than 60,000 people from 144 different countries, has been looking into these and other questions. It is believed to be the largest public study of kindness ever carried out in the world. The results, which are currently the subject of a three-part Radio 4 documentary The Anatomy of Kindness, suggest that people who receive, give or even just notice more acts of kindness tend to experience higher levels of wellbeing and life satisfaction. Other encouraging findings are that as many as two-thirds of people think the pandemic has made people kinder and nearly 60% of participants in the study claimed to have received an act of kindness in the previous 24 hours. Luke Cameron, dubbed the "nicest man in Britain", once spent a year doing a good deed every day. It taught him that sometimes offering some help, reassurance or a kind word can make a huge difference. "It's made me more aware of things that happen in front of me. If someone falls over in the street, there's always going to be people who go and help and others who stand back. It's made me one of those people who go and help. Consciously, I now just do it." He became that person, he says, after a "mindset shift" where he realised: "Actually, if it was me, I'd want somebody to help me. That makes you think differently about how you are with people."
