Washington, Nov 20 A new study has shown that the habit of blaming someone in an organisation, even if he or she is innocent, greatly increases the odds that the practice of blaming others will spread with the tenacity of the H1N1 flu.

The blame game spreads quickly because it triggers the perception that one's self-image is under assault and must be protected.

Study's lead author Nathanael J. Fast, assistant professor of management at the University of Southern California (USC) and Larissa Tiedens, professor of organisational behaviour at Stanford, conducted four different experiments and found that publicly blaming others dramatically increases the likelihood that the practice will become viral.

The study is the first to examine whether shifting blame to others is socially contagious.

"Blaming becomes common when people are worried about their safety in an organisation. There is likely to be more blaming going on when people feel their jobs are threatened," Tiedens said.

Fast said: "When we see others protecting their egos, we become defensive too. We then try to protect our own self-image by blaming others for our mistakes, which may feel good in the moment."

However, in the long run, such behaviour could hurt one's reputation and be destructive to an organisation and further to our society as a whole, he added.

"Blame creates a culture of fear and this leads to a host of negative consequences for individuals and for groups," Fast said.

Anyone can become a blamer but there are some common traits. Typically, they are more ego defensive and tend to feel chronically insecure, Fast said.

The results will be published in the November issue of Journal of Experimental Social Psychology. (ANI)
