LONDON, March 26: A British mathematician has formulated a formula to predict whether loved-up couples are bound to spend their lives together or end their marriages in divorce.

Oxford University professor James Murray said his formula successfully predicted whether a couple would divorce 94 per cent of the time, in a study of 700 newly-married couples.

“Some couples might as well get divorced right away,” said Mr Murray, who was to present his findings to the Royal Society in London, after receiving one of its oldest awards. As part of the research Mr Murray and his team filmed the newlyweds discussing contentious issues such as money or sex for 15 minutes, and graded each statement made during their respective turns of speech.

Statements with humour or affection were given positive scores, while those with defensiveness or anger were given negative ones. The resulting scores were used to identify whether the relationship was likely to stand the test of time.

The couples were then contacted over one to two year intervals over a period of 12 years, with Mr Murray’s formula correctly predicting the divorce rate with an accuracy of 94 per cent.

In separate research presented at the Royal Society’s Bakerian lecture, Mr Murray found that high-grade brain tumours are much more predictable than is generally thought.

Using two MRI scans taken before a patient undergoes treatment, Mr Murray found that patients would often be better off avoiding surgical removal of the tumour, and could predict the patient’s approximate survival time.—AFP
