Abstract

The hypothesis that best explains the Flynn effect is the “rising tide” hypothesis: as public health, in general, improves, children become healthier and better able to demonstrate their innate intellectual ability. Improved health leads to improved mental acuity; if a child is not riven with chronic diarrhea, he will be better able to focus, better able to think, and better able to learn. There is a simple truth here: what is good for the body is good for the brain. Physical health and intellectual health are inseparable; if a child is physically stunted, he will be cognitively stunted as well [1]. However, there is a larger truth here: any intervention that is good for children is good for society, since children are society’s most precious resource.
