Why do so many studies link maternal intelligence to success?
Is it the related factors such as less likely to grow up in poverty, emphasis on education, more likely to find decent partner rather than abusive one? Or are those not relevant anymore? Have there been any recent studies to show that this is still the case?
I'm reasonably educated and have a job which uses my degree, however I'm working so hard I definitely don't have the amount of time to dedicate to spellings, reading, facilitate lots of time to supplementing their education or exploring their interests. I think there could be more exceptions to the original evidence around maternal intelligence.
Also is this only measure by academic achievement or is there any other measure which includes different types of intelligence?
