Where culture is a great factor --- In Asian culture they never admit mistakes. It is humiliating for them. They believe if they say sorry, they are finished! Instead they will paint it and impose you back. If parents scold children for poor results then children commit suicide (both are wrong). For Japanese, they rehearsal presentation/speech thousand times and during delivery if they found it was not expected one then they commit suicide.
