The researchers carried out their study in order to try to answer a long-standing question for economists and medical researchers as to whether social status alone can affect people's well being and lifespan. Although the existence of some kind of effect is known from studies of monkey packs, in humans it has been difficult up till now to separate any perceived positive effect of "status" from the effect of simple greater wealth that status often brings.

Nobel Prize winners were viewed as an ideal group to study as the winners could be seen as having their status suddenly dropped on them. They also come with a ready made control group they can be directly measured against - scientists who were nominated for a Nobel prize but did not actually win one. The researchers looked at winners and nominees in physics and chemistry between 1901 and 1950 (the full list of nominees are kept secret for 50 years). This gave them 528 male scientists with known biographical details (birth and death dates). They looked at one sex only to avoid differences in life span between sexes.

The average life span for the group who won the Prize was just over 76 years. Winners of the Nobel Prize were found to live 1.4 years longer on average (77.2 years) than those who had "merely" been nominated for a prize (who lived on average for 75.8 years). When the survey was restricted to only comparing winners and nominees from the same country, the longevity gap widened even more by around another two thirds of a year on average.

Professor Andrew Oswald, an economist at the University of Warwick, said: "Status seems to work a kind of health-giving magic. Once we do the statistical corrections, walking across that platform in Stockholm apparently adds about 2 years to a scientist's life-span. How status does this, we just don't know."
