How Smart will your Children Be?

A lifetime's observations, as a parent, trustee and teacher, confirm what renown psychologist James Flynn (Flynn effect) and Caltech Polymath assert. Regression to the mean, as described by Gregor Mendel and Francis Galton among others, is real. The average intelligence of children of very bright people will be somewhat lower.

My contribution is a graphical demonstration that Flynn and Hsu must be right in order for average intelligence and the standard deviation (width of the bell curve) to remain constant from generation to generation.

But - there is a wide distribution. Some will be smarter. Whatever the case, no interventions yet have permanently raised IQ. However, a stable family and school environment certainly helps a child make the most of whatever intelligence they have.
