资源稀释模型认为，父母的资源是有限的，随着家庭中孩子数量的增加，任何一个孩子所积累的资源必然会减少。兄弟姐妹是父母时间、精力和经济资源的竞争者，因此越少越好。即使是一个兄弟姐妹也太多了。作者描述了稀释位置的一般要素，并评估了其在解释兄弟姐妹对教育过程的一个组成部分（智力发展测试）的影响方面的优点。作者指出了最近对稀释立场的批评中的关键缺陷，并得出结论，稀释继续为为什么兄弟姐妹少的孩子在认知技能测试中比兄弟姐妹多的孩子得分更高提供了最有希望的解释。
The resource dilution model posits that parental resources are finite and that as the number of children in the family increases, the resources accrued by any one child necessarily decline. Siblings are competitors for parents' time, energy, and financial resources and so the fewer the better. Even one sibling is too many. The author describes the general elements of the dilution position and assesses its merits for explaining the effect of siblings on one component of the educational process-tests of intellectual development. The author identifies critical flaws in recent critiques of the dilution position and concludes that dilution continues to provide the most promising explanation for why children with few siblings score higher on tests of cognitive skills than children with many siblings.
