The reason why there are individual differences in intelligence goes beyond psychology and takes into account a wide range of issues including moral, ethical, social and educational among many others. That is why the subject of how differences in intelligence between persons and groups is of great deal of interest and debate as it can stir up tough reactions and bring out personal beliefs and biases (Howe, 1997).
In analyzing the link between what is inherited and what is nurtured from experience, a number of scholars have argued that nature's contribution to individual differences in intelligence as a force to be considered and educated or controlled (Anastasi & Urbina, 1997). In other words, nature is always a truth to contend with in relationship to these differences.
Some scholars have however moved away from the position that knowledge is subjective to every individual. They have therefore argued that the human mind is a dynamic player in knowledge attainment, constructing specific facets of an experience (Howe, 1997). This is because they think that each individual inherits particular kinds or concept grids on which experiences could be arranged and/or organized (Kline, 1991).

For instance, why should a preference be made converse to an individual's chosen preferences or which may lead in real retribution? Altruism for not-related persons, straightforwardness and integrity as fairness are values hard to support from an evolutionary perspective, especially when some preferences cause the demise of an individual, effectively getting rid of those...
