More people have ventured into the potentially hazardous waters of online dating than would care to admit - and some of their adventures have been truly hair-raising. Now a group of former Harvard math majors are crunching the data to reveal the secret tips of the online dater, displaying them in - naturally - graph form。

　　Men, for example, should show off their six pack if they have one - but only if they're young. Meanwhile women should always flirt with the camera - but men should look aloof。

　　The OkTrends blog found at dating website OkCupid have been charting various trends - such as how long relationships last among Twitter users - since 2009. One of the blog's tips is to ask your date if they've ever wanted to run away to sea, whether they enjoyed the Blair Witch Project, or their past travel experiences。

　　The reasoning, the bloggers explained, was that according to the thousands of multiple choice "match questions" answered by OkCupid's seven million users, couples who met on the site agreed most often on three questions in particular: "Do you like horror movies?", "Have you ever travelled around another country alone?", and "Wouldn't it be fun to chuck it all and go live on a sailboat?"

　　Experts said that these types of questions are measuring the "openness to experience" or the O Factor. “People who seek stimulation and adventure... they'd be less likely to establish and comfortably maintain a relationship with very traditional, conservative, unimaginative, risk-avoidant individuals,” said Western Carolina psychology department head David McCord。

　　Women were also told to flirty with the camera for their profile photo. If so, they received on average 1.5 additional messages per month。

　　That's because a woman's smile is well-documented as a signal of sexual interest, said University of Texas psychology professor David Buss. When men were ordered to be aloof on camera, they had a roughly 90 percent success rate with their emails than otherwise. Smiling is sometimes interpreted as a sign of submissiveness。

　　The data also showed that women who showed a bit of cleavage had better results - vastly better results as they got older. Women's mate value declines with age, but they can compensate for their decline in mate value by showing their cleavage。

　　According to OkCupid, an 18-year-old woman with a cleavage shot in her profile gets 24 percent more contacts per month on average than more demure 18-year-olds. If she does it at age 32, that jumps to 79 percent。

　　For men, the inverse is true. Male online daters should show off their six packs in their profile pictures, but only if they are young. That's because women in their 30s are less interested in the man's body than whether or not he will be a good provider. Women who see and older man showing off his abs will just think he is silly。

　　Another tip was both to subtract two inches from the height your potential date claims to be - and 20 percent from their salary. For men, the experts said, this makes sense. Height suggests good health and genes; while wealth, obviously, suggests resources. Men deceive about their status and income in order to make themselves seem more desirable to women, stated Dr Buss. Women, however, may not be lying。

　　If a woman is trying to get dates online, according to experts, she must be having difficulty in real life. That could be because she is Amazonian. They also may have a bigger paycheque than the average man。

　　如今已有越来越多的人放下面子加入网络约会的冒险大军，其中有些人的经历可谓真正的冒险。日前，一群毕业于哈佛的数学高材生们绘制了一系列图表，用数据揭秘网络约会技巧。

　　比如男人只要有条件就秀出自己的六块腹肌——但是你得够年轻。同时女人面对镜头时也应该风情万种，这当然和男人要装酷完全不同。

　　自从2009年以来，这群数学家一直在相亲网站“OK丘比特”上的“OK风尚”博客内用图表研究种种趋势，比如Twitter用户之间的感情能维持多久。该博客还支过一招，就是教网友问一下男/女朋友，是否曾经期待私奔到海边，是否喜欢电影《女巫布莱尔》或者是问他们是否有旅行经历等。

　　博主解释道，这样发问的原因在于，根据700万“OK丘比特”受众所作的成千上万个匹配问题答案显示，网上认识的情侣在三大问题上会给出肯定的回答。这些问题是：“你喜欢恐怖片吗？”，“你孤身到外国旅游过吗？”以及“你不觉得抛下一切去海上漂泊很有意思吗？”。

　　专家称上述类型的问题主要是考察“经验的开放性”或曰0因素。西卡罗莱纳州的心理学系主任大卫？麦科德指出，寻求刺激或冒险的人，不大可能与一个传统、保守、缺乏想象力、不敢冒险的人顺利建立一段关系。

　　博文中建议，女人上传的相亲照片应摆出调情之态，这样的话，每个月收到的联系信息会多出1.5条。

　　田纳西州立大学心理学教授巴斯称，因为女人调情的笑容是一种性讯号。对于男人而言，通过表情冷酷的照片网上的相亲成功率可以比平常相亲高出90%。男人微笑会被女人解读为不够硬朗。

　　文章数据还显示，女人露点乳沟的话，效果会更好。而且，这种情况更适合与年长的女性。专家解释，随着年龄增长，女人的竞争力降低，但是露点能够弥补这一缺憾。

　　“OK丘比特”网站的观察显示，一位18岁的女孩在相亲网上照片上露点乳沟的，其点击量将比同龄人高每个月高24%。如果年龄到了32岁，那么该数据则高达79%。

　　对于男人而言，情况恰恰相反。男性网友应该在照片上大秀腹肌，但是前提是得年轻。原因是三十几岁的女人更感兴趣的是男人的经济能力，而不是身材。如果一个老男人秀自己的肌肉的话，女人会觉得他很傻。

　　该文章支的另外一招就是，你得将征友者所声称的身高减去2英寸，然后在减掉他们声称收入的20%。专家称，这两点对男人意义重大。身高意味着健康和基因，而收入意味着财力。巴斯教授指出，他们在这两个问题上撒谎是为了使自己更具竞争力。而女人一般不会在此问题上撒谎。

　　专家还指出，如果有女人试图在网上征友，那她生活中肯定遇上了困难。比如说，她有可能长得特别高。这些网上征友的女人可能赚得比一般男人要多。
