Heredity> Environment or Environment > Heredity? Will Mathematics answer or not


By assigning values to the alphabets in English language, E takes the value of 5 and H takes the value of 8. Mathematically 5< 8 no doubt about it. But it is not true when the debates are on Heredity and Environment. Kurt Lewin says that for an individual development (defining development is… bit tricky) both the above said factors plays a crucial role. Myriad research studies assert the individual IQ depends on the brain size. Let us exile a child with bigger brain size to unhabited place; will his IQ be more after analyzing after few years? On the contrary if the average brain sized child lives amongst the conducive environment his IQ will be more than the average.  Debate though seamlessly unending; I am skeptical about the IQ tests that are designed. Do those tests have cultural fluidity? Though IQ has some quantitative measures, it is qualitative in nature too.
If Heredity & Environment both contributes (let us say) then what about the Intellectually Disabled children? They are categorized into educable, trainable and custodial. How IQ frame can be fit to the children with disabilities?
