So it’s nothing to do with talent and all to do with running order. That’s the reason imagewhy Jedward were booted out of X-Factor, according to researchers at Cambridge and London universities.

But is there a lesson here for our aspiring parliamentary candidates?

Researchers who analysed data from 165 series of X-Factor and Pop Idol discovered that running order was crucial to winning.

Their study concluded that contestants who performed last were most likely to receive the highest proportion of votes, followed by those who performed first. But those who appeared second or third in a round were the most likely to be eliminated that week.

No wonder Jedward didn’t stand a chance when they performed in third place on X-Factor the day before they were eliminated. The odds were stacked against them from the very  beginning. Researchers say viewers are less able to remember earlier performances and are more likely to vote for later performances which are fresh in their mind.

The study was led by Dr Lionel Page of Judge Business School, Cambridge University, and Dr Katie Page of Heythrop College, University of London. They believe the findings could be helpful for candidates who are judged sequentially, such as job interviews or competitions.

This could equally apply to political candidates when they are up for selection and take it in turns to make their X-Factor pitch. I wonder how many successful candidates were first or last in the line up on their big day.
