If it provides more interests than drawbacks, genetic enhancement could be supported and could be applied. But if the drawbacks exceed benefits, genetic enhancement must be curded. Taking account of consequences is the perspective of utilitarianism, and hence a good starting for our considerations. Peter Singer, a utilitarian, and his preference utilitarianism and the principle of equal consideration is naturally the best choice for such discussions. His point of view gives weights to the preference of parents, society, and environment and puts the account of interest in genetic enhancement more in focus.

而如果要从利益的多寡来看待基因增强，则以功利主义的角度为出发点就会是相当合适的，因为功利主义在考量一件事情的可行性，就是要考量到所有受到事件影响的事物，当把全部的利益都计算进去，才能够了解这件事所带来的利益是否大於弊端，辛格是一位功利主义者，而且他还著重於每个人偏好的考量，对於地球上所有物种的利益也都平等看待，因此，以他的观点做为本篇论文的论据，在计算基因增强所带来的利弊之外，还能够更贴近每位受到基因增强影响的父母、社会、环境的偏好，将利益的计算考量的更加缜密。
