People regretted what they have done, and what they wished they hadn’t done, far more than what they had not done and perhaps should have. The pain that is experienced when the loss is caused by an act that modified the status quo is significantly greater than the pain that is experienced when the decision led to the retention of the status quo.


When choosing between sure things and gambles, people’s desire to avoid loss exceeded their desire to secure pain.


People did not chose between things. They chose between descriptions of things. Economists, and anyone else who wanted to believe that human beings were rational, could rationalize, or try to rationalize, loss aversion.
