If you argue with your friend, will you forgive (原谅) him or her? Most people prefer to forgive others. Researchers from Yale University, the University of Oxford and University College London have found that we tend to (倾向于) believe that people are _____ at heart, even when they have behaved badly. And when these “bad people” do something nice, people will be likely to forgive their past mistakes and have a positive opinion of them.
