It's often said that men are from Mars while women are from Venus. But, now a new book says that they're from the same planet — the difference between them is actually down to the way they are brought up. According to the book, 'Delusions of Gender', penned by Cordelia Fine, a Melbourne University psychologist, it's nurture, and not nature, which explains why men and women are so different. In fact, nurture has the largest effect on skills, attributes and personalities of men and women. So boys aren't born with better map-reading and parking skills; girls do not come into the world with better multitasking and communicating skills, the 'Daily Mail' reported. According to the book, there are no major neurological differences. There may be slight variations in the brains of women and men but the wiring is soft, not hard. Dr Lise Eliot, of Chicago Medical School, agrees. "Children don't inherit intellectual differences. They learn them. They're a result of what we expect a boy or a girl to be. Yes, boys and girls, men and women, are different. But most of those differences are far smaller than Men are from Mars, Women are from Venus stereotypes suggest," she said. Prof Robert Plomin of Institute of Psychiatry, London, added:"Every skill, attribute and personality trait is moulded by experience. People ignore huge similarity between boys and girls and instead exaggerate wildly tiny difference between them. It drives me wild."
