Silver (1982) researched the effects of a traumatic accident on one's baseline level of happiness. Silver found that accident victims were able to return to a happiness set point after a period of time. For eight weeks, Silver followed accident victims who had sustained severe spinal cord injuries. About a week after their accident, Silver observed that the victims were experiencing much stronger negative emotions than positive ones. By the eighth and final week, the victims' positive emotions outweighed their negative ones. The results of this study suggest that regardless of whether the life event is significantly negative or positive, people will almost always return to their happiness baseline.
