"When something doesn't meet our expectations, many of us operate with the assumption, "When in doubt, it must be someone else's fault". You can see this assumption in action almost everywhere you look -- something is missing, so someone else must have move it; the car isn't working right, so the mechanic must have repaired it incorrectly; your expenses exceed your income, so spouse must be spending too much money; the house is a mess, so you must be the only person doing your part; a project is late, so your colleagues at work must not have done their share -- and on and on it goes".
"This type of blaming thinking has become extremely common in our culture. On a personal level, it has led us to believe that we are never completely responsible for our own actions, problems or happiness. On a societal level, it has led to frivolous lawsuits and ridiculous excuses that get criminals off the hook. When we are in the habit of blaming others, we will blame others for our anger, frustration, depression, stress and unhappiness".
