Some consequences of childbearing for the parents and children are partly expected by the parents, while others to a larger extent are unexpected. Also, some are rather general while others vary greatly between individuals. In principle, it would be valuable for individual fertility decision-makers to learn about consequences of childbearing that they are currently not aware of. This can be achieved by disseminating existing expert knowledge about effects that are likely to be poorly known to the public, and by doing further research on effects of childbearing. Knowledge about effects that are rather general, such as those involving physiological mechanisms, would be particularly valuable. Other effects, which may be described as social–behavioural, are to a larger extent expected and varying, and are therefore both harder to estimate and less important for individual decision-makers to learn about. For politicians and planners, knowledge about all types of consequences may be helpful, and perhaps especially those that are rather general.

研究记录：理想情况下，我们对学习什么样的个人层面的影响感兴趣？预期，意外，变化和一般影响之间的重要区别

父母对孩子生育的某些后果在一定程度上是父母期望的，而其他后果在很大程度上是意料之外的。而且，有些是比较笼统的，而有些则因人而异。原则上，对于每个生育率决策者来说，了解他们目前尚不了解的生育后果将是有价值的。这可以通过传播有关可能不太为公众所知的影响的现有专家知识，以及对生育影响进行进一步研究来实现。有关相当普遍的影响（例如涉及生理机制的影响）的知识将特别有价值。其他影响（可能被描述为社会行为）在很大程度上是预期的和变化的，因此，这对于每个决策者来说都很难估计，也不太重要。对于政治家和计划者来说，了解所有类型的后果可能会有所帮助，尤其是那些比较笼统的后果。
