????如今的婚戀交友網(wǎng)站五花八門，總有一款適合你。這些網(wǎng)站通過宗教背景、飲食偏好、外貌身材等各種標(biāo)準(zhǔn)來為你篩選伴侶，有的甚至專門服務(wù)于擁有傳統(tǒng)觀念的鄉(xiāng)村居民，比如Farmersonly.com。照這樣發(fā)展下去，總有一天擇偶標(biāo)準(zhǔn)將不再限于共同的興趣愛好，而開始涉及到個(gè)人基因信息。

????SINGLDOUT是一家圣地亞哥的初創(chuàng)企業(yè)，他們推出的新交友網(wǎng)站就設(shè)計(jì)出一種專屬的計(jì)算方法，通過DNA分析和心理測試來為單身人士配對。

????目前市面上的婚戀網(wǎng)站大多由男性創(chuàng)建，因此，由兩位女性創(chuàng)建的SINGLDOUT倒有些物以稀為貴。亞娜?巴亞德?lián)问紫瘓?zhí)行官，艾麗?弗蘭斯則是銷售總監(jiān)，二人建立婚戀網(wǎng)站的想法來源于自己的擇偶經(jīng)歷。

????“在擇偶問題上，生物界和數(shù)字世界之間存在著差異，SINGLDOUT是第一家彌合這種差異的婚戀網(wǎng)站。”巴亞德說，“這是婚戀交友網(wǎng)站的進(jìn)步。”

????這家網(wǎng)站主要面向閑暇時(shí)間不多的白領(lǐng)人士，讓他們能在第一時(shí)間就找到自己感興趣的個(gè)人資料。擁有電商背景的巴亞德說：“從DNA的角度來看，我們發(fā)現(xiàn)可以通過基因比對結(jié)果來確定兩個(gè)人是否來電。”而且，網(wǎng)上個(gè)人資料可以造假，DNA卻不能。

????與SINGLDOUT合作的Instant Chemistry是一家位于多倫多的實(shí)驗(yàn)服務(wù)公司，負(fù)責(zé)進(jìn)行DNA測試，并確定會(huì)員的基本基因?qū)傩浴２杉疍NA的過程非常簡單：會(huì)員打開已預(yù)付郵資的信封，在采集盒中提供唾液樣本，然后寄往Instant Chemistry。這只是找到緣分的第一步，要確定約會(huì)對象還需要進(jìn)行大數(shù)據(jù)分析。

????分析主要針對兩項(xiàng)特定的DNA數(shù)據(jù)。其一是血清素傳輸基因的長度，它可以決定人的情緒性格。研究表明，血清素傳輸基因較短的人大多比較感性，而基因較長的人則比較沉穩(wěn)。憑借其獨(dú)家運(yùn)算技術(shù)，SINGLDOUT向兩位可能有緣的會(huì)員發(fā)送基因比對結(jié)果，并且詳細(xì)介紹兩人如何在實(shí)際生活中產(chǎn)生交集。

????另一個(gè)數(shù)據(jù)是關(guān)于調(diào)節(jié)人體免疫功能的白細(xì)胞抗原系統(tǒng)。通過對這項(xiàng)指標(biāo)的分析，可以確定兩人在生理上是否互相吸引。SINGLDOUT引用了多項(xiàng)研究結(jié)果來支持其“異類相吸”理念。【其中之一是2006年發(fā)表于《精神科學(xué)》（Psychological Science）的一項(xiàng)研究結(jié)果。該項(xiàng)研究發(fā)現(xiàn)，男女雙方的基因匹配比例越高，女方對男方的性敏感程度就越低，對男性的吸引力也越低，而比例較低的男女反而越高】。

????The world of online dating has something for everyone. Sites are dedicated to picking partners based on religion, dining preferences, pure physical attraction and the good, old-fashioned values of cowboy life (at Farmersonly.com, of course). So it was only a matter of time before a website took the next step beyond shared interests and tapped into genetic profiling.

????SINGLDOUT, a San Diego-based start up, has devised a proprietary algorithm that matches singles based partly on DNA compatibility and partly on the results from a psychological questionnaire.

????In a rare twist for the dating website industry, which is dominated by male company founders, SINGLDOUT was started by CEO Jana Bayad and chief marketing officer Elle France, who hatched the idea based on their own dating experiences.

????“SINGLDOUT is the first online dating website that is going to bridge the gap between the biological and digital worlds of love,” says Bayad. “It is the evolution of online dating.”

????The website is aimed at time-crunched professionals who want to know from the outset that they will click with the person who looks good in a profile. “When we looked at it from a DNA viewpoint, we realize you could actually determine chemistry between two people based on their genes,” says Bayad, who has an online sales background. Plus, DNA doesn’t lie, unlike so many dating profiles.

????SINGLDOUT works with Instant Chemistry, a Toronto-based lab services company that administers the DNA testing and determines the basic genetic profiles of members. For the member, this part is as easy as opening a prepaid envelope, providing a saliva sample in the DNA kit and sending it back to Instant Chemistry. It’s a clinical way to start a budding romance, but no more so than relying on big data to set up a date.

????The research hones in on two specific results. The first is the length of the serotonin transporter gene, which influences emotion. Research has suggested that those who have the shorter gene tend to be more emotionally sensitive while those with the longer gene tend to be more emotionally stable. Based on the results of their proprietary algorithm, SINGLDOUT sends the two potential partners a compatibility percentage with a broad explanation of how they might interact in real life.

????The second DNA test looks to determine physical attraction based on the human leukocyte antigen system, which regulates the immune system. SINGLDOUT points to a few pieces of research to make the argument that opposites attract here. (One piece of evidence is a 2006 study published in Psychological Science that found as the proportion of these genes couples shared increased, women’s sexual responsiveness to their partners decreased and their attraction to men other than their primary partners increased.)
