Beauty and brains DO go together! Study claims good-looking men and women have higher IQs

Another of the many positive correlates of IQ

Handsome men and women often appear to be blessed with lucky lives. Now research has shown they are cleverer than most people as well. Studies in Britain and America have found they have IQs 14 points above average. The findings dispel the myth of the dumb blondes or good-looking men not being very bright.

It appears that those already physically blessed attract partners who are not just good looking but brainy too, according to research by the London School of Economics. The children of these couples will tend to inherit both qualities, building a genetic link over successive generations between them.

LSE researcher Satoshi Kanazawa told the Sunday Times: ''Physical attractiveness is significantly positively associated with general intelligence, both with and without controls for social class, body size and health. 'The association between attractiveness and general intelligence is also stronger among men than among women.'

In other research on social standing, he found that middle-class girls tended to have higher IQs than their working- class counterparts.

Among the millions of examples of beauty and brains, there's supermodel Lily Cole who went to Cambridge University, actress Kate Beckinsale, an Oxford graduate, and physicist Brian Cox, one-time keyboard player with D:ream.

In Britain, the study found that men who are physically attractive had IQs an average 13.6 points above the norm while women were about 11.4 points higher.

Kanazawa's findings were based on the National Child Development Study which followed 17,419 people since their birth in a single week in March, 1958. Throughout their childhood up to early adulthood, they were given a series of tests for academic progress, intelligence and marked on appearance.

The American research was taken from the National Longitudinal Study of Adolescent Health which involved a similar study of 35,000 young Americans.

Kanazawa, whose paper was published in the academic journal Intelligence, said: 'Our contention that beautiful people are more intelligent is purely scientific. It is not a prescription for how to treat or judge others.'


Brazilian mothers benefit from vitamin pills

Brazil is a poor country. The pills may have helped make up for nutritional deficiencies

A capsule containing a cocktail of ­essential oils and vitamins could make PMS less painful for millions of women – not to mention the men in their lives. In tests, the natural supplement cut monthly symptoms by up to two-thirds, with minimal side-effects.

It is thought the pills, which contain a mixture of healthy fats and vitamin E, make the body less sensitive to a hormone blamed for much of the misery of pre-menstrual syndrome.

In a study, 120 women were asked to rate the severity of the bloating, tiredness and aches and pains that often beset them in the days leading to menstruation.

Eighty were then prescribed pills containing varying doses of a trio of polyunsaturated fatty acids and vitamin E, which is found in nuts, seeds and green vegetables. Forty women were given packs of dummy pills.

All were told to take two capsules before bedtime each night leading up to their period and asked to rate their symptoms after three months and again at six months.

Those taking the essential oils experienced a clear easing of symptoms after three months. By six months the effects were dramatic, especially among those taking the highest doses.

In some of these cases the severity of ­symptoms fell by more than two-thirds, the journal Reproductive Health reports. Side-effects were rare, with one woman experiencing stomach ache and another’s period starting later than usual.

The researchers, from the Federal University of Pernambuco, in Brazil, believe the contents of the capsules make the body less sensitive to prolactin, a hormone blamed for fluid retention and breast tenderness.

Reacting to the study, Nick Panay, a consultant gynaecologist, questioned whether the capsules would relieve psychological symptoms such as mood swings or low self-esteem. But he added: ‘It sounds encouraging and it is good to see that people are doing proper trials.’
