DESCRIPTION (provided by applicant): Family life is widely viewed as having a profound influence on both children and adults. However, broad changes in family structure have contributed to evolving, and controversial, ideas about what makes a "normal" or "healthy" family. Social scientists contribute both to basic knowledge about family life, and to social programs and political debates, by studying potential causes and consequences of different family experiences. These efforts are exceedingly important, especially given the prospect of altering family life in order to promote individual health and well-being. Our proposed work contributes to this important effort by focusing much of our effort on the question: Does marriage benefit social, emotional, psychological, and economic well-being - and even physical health and longevity? A large body of research suggests that marriage is correlated with these outcomes, but correlation does not mean causation. Or as two critics of marriage noted in a recent essay, "To say marriage creates wealth is to confuse correlation with causation. If there is more wealth in Manhattan than in Brooklyn, that does not mean that moving to Manhattan will make you wealthier." We are not only concerned that background and personality affects who gets and stays married, but we also know that genetic factors influence the likelihood that people will experience happy marriage or other key aspects of family life. Even as we raise this concern, however, we offer a method - studying twins - that solves not one but two huge scientific problems. Identical twins share the same genes, and they also share the same upbringing. Thus, when we compare identical twins, we eliminate the problem of nonrandom selection into experience based on background, prior experience, personality, and genes. In fact, the twin method allows us to determine cause and effect better than any available research technique, other than randomly assigning couples to marry, or not, divorce, or not, and so on, which, of course, is logistically and ethically impossible. We propose to study five unique samples of twins in the U.S., Australia, and Sweden (each sample offers special benefits) to test whether marriage (and single life, cohabitation, divorce, widowhood, and remarriage) really are likely to cause of the outcomes with which they are correlated. We also propose to study how genes and the environment work together to modify the "marriage benefit" for mental and physical health, including studying specific genes recently documented to influence behavior in close relationships. Finally, in order to enrich our highly technical quantitative analyses, we plan to interview identical twins to learn more about what makes them different, particularly how different experiences in marriage, romantic relationships, and relationship dissolution may alter their life course.

描述（由申请人提供）：家庭生活被广泛认为对儿童和成人都有深远的影响。然而，家庭结构的广泛变化促使人们对什么是“正常”或“健康”家庭的看法不断演变，并引起争议。社会科学家通过研究不同家庭经历的潜在原因和后果，对家庭生活的基本知识以及社会计划和政治辩论做出了贡献。这些努力极其重要，特别是考虑到改变家庭生活以促进个人健康和福祉的前景。我们的工作计划通过将大部分精力集中在以下问题上来促进这一重要努力：婚姻是否有益于社会、情感、心理和经济福祉，甚至有益于身体健康和长寿？大量研究表明，婚姻与这些结果相关，但相关性并不意味着因果关系。或者正如两位婚姻批评家在最近的一篇文章中指出的那样，“说婚姻创造财富是混淆了相关性和因果关系。如果曼哈顿的财富比布鲁克林多，这并不意味着搬到曼哈顿会让你更富有。“我们不仅担心背景和性格会影响谁结婚和保持婚姻，而且我们还知道遗传因素会影响人们幸福婚姻或家庭生活其他关键方面的可能性。然而，即使我们提出了这个问题，我们也提供了一种方法-研究双胞胎-解决了两个巨大的科学问题。同卵双胞胎有着相同的基因，他们也有着相同的成长经历。因此，当我们比较同卵双胞胎时，我们将非随机选择的问题排除在基于背景、先前经验、个性和基因的经验中。事实上，双胞胎方法比任何现有的研究技术都能更好地确定因果关系，除了随机分配夫妇结婚或不结婚，离婚或不离婚等等，当然，这在逻辑上和伦理上是不可能的。我们打算研究美国五个独特的双胞胎样本，澳大利亚和瑞典（每个样本都提供特殊福利），以测试婚姻（以及单身生活，同居，离婚，丧偶和再婚）是否真的可能导致与它们相关的结果。我们还建议研究基因和环境如何共同作用，以改变心理和身体健康的“婚姻效益”，包括研究最近记录的影响亲密关系中行为的特定基因。最后，为了丰富我们高度技术性的定量分析，我们计划采访同卵双胞胎，以了解更多关于是什么使他们不同，特别是婚姻，浪漫关系和关系解除的不同经历如何改变他们的生活历程。
