A person’s learning and ability derives from a combination of genetics and environment. Nature may include some form of cognitive inherits from parents, and nurture includes the process of inferential and experiential learning that registers in the brain.
There are many components to intelligence. Memory, comparative behavior, planning behavior, classification, choice of inputs and outputs, language etc.
One important element is the use of time, not only “quality” but quantity time. Intelligence involves elements of knowing what is right or neccessary, but without proper guidance or mentoring, this intelligence is applied ” selectively” in the face of benefits and threats. Thus, it is important to guide the children in coupling intelligence with values and applications for a healthy individuals, and not intelligence as a unit only.
