First born children are more intelligent science finds
Quote:
The first child born to a family is more likely to be clever than their brothers and sisters, a new study has suggested.
New research carried out in a German University found that the eldest child in a family has a higher IQ than their younger siblings due to the level of attention they are bestowed in their early years.
Scientists discovered that parents make a greater effort to encourage learning with their first child than they do when it comes to their second, third and fourth children.
The researchers found a difference of 1.5 IQ points between each sibling in a family after taking into account three national surveys which documented the IQ results of more than 20,000 people.
A recent study found that older sisters are 40pc more likely to be obese than their younger sisters and 29pc more likely to be overweight.
