幸福难解释幸福更难

Scientists have been hunting the precise mechanism through which a positive state of mind exerts a beneficial effect on our biology. Barbara Fredrickson, a psychology professor at the University of North Carolina, published a startling paper in 2013 suggesting that the genomic profile of deeply contented people differed measurably from those of others, possibly influencing im洀甀渀攀 function. The finding provoked publicity and then controversy; one reanalysis using Prof Fredrickson’s data failed to reach the same conclusion.

科学家一直在寻找积极心态产生有益生理影响的精确机制。2013年，美国北卡罗来纳大学(University of North Carolina)心理学教授芭芭拉弗雷德里克森(Barbara Fredrickson)曾发表一篇令人震惊的论文，提出深层次满足的人群的基因组图谱与其他人显著不同，这可能会影响免疫功能。这一发现得到了广泛报道，随即引发了争议；根据弗雷德里克森教授的数据重新开展的一项分析未能得出相同结论。

None of which should stop us from trying to discern the elements of a happy life. This is the goal of the Greater Good Science Center at the University of California, Berkeley, which combines re猀攀愀爀挀栀 on happiness with practical recommendations.

Contentment stems not from material wealth, as the rich keep reminding us, but from relationships and personal development. Compassion and altruism seem central.
