My observation which I have discussed with many individuals is that the younger ones are smarter. Reasons are also straight forward. For one, the younger one gets earlier exposure to new stuff on account of elder siblings activities. Perhaps parents are also forced to focus on activities on the younger one at the expense of the elder kid. What I do concede is that older ones probably will have higher emotional quotient (They are the ones who bear the brunt of sharing, the trauma of neglect, the burden of teaching etc etc. There is no doubt that these help them in being better prepared for the outside world, which can explain for there higher rating. EQ perhaps is more important than IQ to get success.
Or perhaps Norwegians bring their kids differently as compared to Indians!!
