From the article:
"The study of 75 seven-year-old children found those with shorter ring fingers than their index fingers did better in tests at literacy than maths.
The research team compared the ratio between the two fingers with the seven-year-olds' school test results, and said they found a 'valid relationship' between them.
Dr Brosnan said: 'We're not suggesting that finger length measurements could replace SAT tests.
'Finger ratio provides us with an interesting insight into our innate abilities in key cognitive areas.' ""
