It’s all social conditioning. You are socially conditioning your child to be good at math. Good for you. It would be very hard for me to group you together with others and formulate a trend. As we zoom out and evaluate the aggregate picture your outlier datapoint is swallowed up and culture becomes the dominant mediator.

You can reject all you want but your [personal, anecdotal] data point is irrelevant.

It takes a village to raise a child.

[rejecting an analysis because you disagree with the premise is unscientific - this analysis exposes a trend - it does not make a prediction - but gives pointers for further analysis]
