Science and Technolgy.The joys of parenthood.Father's day.Having children really does make a man more content with life.WILL fatherhood make me happy?That is a question many men have found themselves asking, and the scientific evidence is equivocal.A lot of studies have linked parenthood-particularly fatherhood-with lower levels of marital satisfaction and higher rates of depression than are found among non-parents.Biologically speaking, that looks odd. Natural selection might be expected to favour the progeny of men who enjoy bringing them up. On the other hand, the countervailing pressure to have other children, by other women, may leave the man who is already encumbered by a set of offspring dissatisfied.To investigate the matter further Sonja Lyubomirsky, a psychologist at the University of California, Riverside, decided both to study the existing literature, and to conduct some experiments of her own.The results, just published in Psychological Science, suggest parenthood in general, and fatherhood in particular, really are blessings, even though the parent in question might sometimes feel they are in disguise.Dr Lyubomirsky's first port of call was the World Values Survey. This is a project which gathers huge amounts of data about the lives of people all around the planet.For the purposes of her research, Dr Lyubomirsky looked at the answers 6,906 Americans had given, in four different years, to four particular questions.
科技。为人父母的快乐。父亲节。拥有子女确实能让男人对生活更加满意。父亲的身份能让自己幸福快乐吗？很多男人都会问自己这个问题，但是至今依然没有一个明确的科学解答。很多关于父母身份（特别是父亲）的研究都显示，有子女的父母有着更低的婚姻满意度和更高的忧郁症比例。从生物学角度来说，这有点奇怪，因为自然选择趋向于选择那些乐于带孩子男人的后代，反过来看，男性要和其他女性生育更多子女的压力可能会让那些已有子女的父亲感到不满。来自加州大学河滨分校的心理学家Sonja Lyubomirsky进行了更为深入的研究，她从现有文献和自己的实验同时入手，其结果发表在《心理学》上。研究表明，父母身份，特别是父亲的身份是相当重要的，尽管那些问题父母有时候可能并没有注意这一点。Lyubomirsky博士首先进行世界价值观调查，这个步骤要收集生活在世界各地的人的大量数据。为了达到研究目的， Lyubomirsky博士在四个不同的年份分别询问了6906个美国人四个不同的问题.。
