To analyze the answers, the team created a data-driven coding scheme, showing that the ten most frequently mentioned categories were science, humanism, critical skepticism, natural laws, equality, kindness and caring, care for the earth, left-wing political causes, atheism, and individualism and freedom. The research demonstrates that there is a range of secular beliefs, clustering together in scientific worldviews, humanist worldviews, and caring nature-focused worldviews, which provide answers the big questions about life.
