The power of empathy

What can we learn by putting ourselves in another's shoes? Imagine. A man in a car overtakes you on a motorway and speeds off. You are annoyed, and immediately think of him pejoratively as 'the sort of person who overtakes'. You use what you think about 'overtakers' to fill in the all the unknowns about this driver, and imagine his entire character to be a reckless, aggressive, and selfish. You mutter to yourself that he probably does anti-social things like this all the time
