A lot of issues raised here. Very thought provoking. One is if your children are all high achievers does this imply the parents are intelligent?    A family with many siblings ....the eldest lives the successful financial life yet could be described as the least happy in terms of life experience satisfaction therefore intelligence and  success may not be a predictor of happiness. The youngest shows signs of high intelligence also. The mother had a higher exposure to good nutrition for the gestation of this child and more availability of sleep. The idea of fixed  mindset versus growth mindset and that this may be influenced would have been nice to touch on as it informs the basis of teacher. education. That sweet spot of intelligence may be linked to eq. We will all relate what we think we know to personal experience either direct or indirect therefore nurture will inevitably play an important role in long term memory retention.<br>Nice to grapple with these questions and i thoughly enjoyed the discussion. One good reassurance is we can all enjoy love and life's beauty if we are kind to one another regardless of intelligence. 😊
