Researchers said that at their core, the male of the species had changed little since Neanderthal times, when reproduction was their prime objective.

研究人员称，自穴居的尼安德特人时代起，繁衍后代就是雄性物种的主要目标，而至今他们依然没有太大的变化。

The US scientists spoke¹ to a sample of men and women to draw up a list of 88 factors that made women appear more "exploitable" - such as those who bite their lips or look sleepy - or suggested they were attention seekers.

美国科学家通过抽样选出了一些男女，交流后得出了让女性看上去更“吸引人”的88个因素：比如那些喜欢咬嘴唇或者看上去睡眼朦胧的女生。这些因素表明哪样女生会吸引更多的关注。

They then showed photos of women illustrating² this type of behaviour or characteristic to 76 other men and asked them to rate how desirable they found them, the Daily Mail reported.

根据《每日邮报》报道，科学家将具备这些行为或特征的女性照片展示给76位男士，并要求他们按照满意程度给这些女性打分。

A physical vulnerability such as being short did not result in the men finding the women more sexually attractive.

一些身体上的不足，比如个子矮小，并没有影响到男士们对她们吸引力和魅力的评判。

But psychological vulnerability - such as when the women were immature³ or unintelligent - resulted in them being given a higher rating, according to the study by researchers at Texas-Austin University.

然而德克萨斯大学奥斯丁分校的这项研究表明，一些心理方面的弱点，比如那些看起来不够成熟或者不够聪明的女性，反而得到了更高的分数。

The men also ranked these women as more attractive than those who were portrayed⁴ as brainy, they found.

研究人员还发现，男士们还认为这些女性比那些看起来聪明的女性更有吸引力。

However, their interest fell off significantly when they were questioned about their interest in pursuing a longer-term relationship with the "dumb" women.The study concluded: "The assessment⁵ of a woman's immediate⁶ vulnerability may be central to the activation⁷ of psychological mechanisms⁸ related to sexual exploitation."

然而，当被问及是否有兴趣和这些“笨笨的”女生有保持长期来往时，男士们的兴趣一落千丈。研究总结表明：“对于一位女性显而易见的弱点的评价，在关系到她受欢迎程度的心理机制的激化中很可能起到核心作用。”

Relationships expert Jean Hannah Edelstein said: "It's not a recipe for a happy relationship to select a partner based on what you perceive to be their inferiority."

两性关系专家艾德斯坦说：“根据你感知到的对方的弱点来选择伴侣，是无法保证一段感情会愉快地发展下去的。”
