If we are insecure, we make fun of others. If we're comfortable being wrong, we're not afraid to poke fun at ourselves. Laughing at ourselves reminds us that although we might take our decisions seriously, we don't take ourselves seriously. Research suggests that the more frequently we make fun of ourselves, the happier we tend to be. Instead of beating ourselves up about our mistakes, we can turn some of our past misconceptions into sources of present amusement.
