Intelligence quotient is not a trait, it is a resource for much of human activity. This is why there is no correlation between intelligence and things like conscientiousness or consciousness. The more you raise this intelligence in your community, virtuousness and vices will grow equally. Therefore, any efforts you take in promoting education must never take place until your children are taught the virtues needed to perform the duties and responsibilities that come with being a member of a community.
All of life as we know it is in a state of progress toward attaining or manifesting the one frequency of our existence. That is to say that a tree is doing its best to reflect the same frequency that you are but in the best way it knows how. Everyone is like a different flower attempting as best they can to reflect the same image. Or a different instrument manifesting a different sound from the same breath. Unless of course you choose to deny this duty, in which case you will bring suffering to yourself and others.
