一項(xiàng)研究發(fā)現(xiàn),，在網(wǎng)上約會(huì)者中間,，在從不同種族的人那里獲得浪漫的表示之后其反對(duì)發(fā)起跨種族交流的偏見減少了,。
Kevin Lewis研究了一個(gè)網(wǎng)上約會(huì)網(wǎng)站的使用者接觸或避開不同種族的人的程度,。這位作者分析了網(wǎng)上約會(huì)網(wǎng)站OkCupid的12萬6134名使用者在2.5個(gè)月里的數(shù)據(jù),，包括使用者的履歷信息和使用者之間交換的所有消息,。
正如此前關(guān)于浪漫關(guān)系的研究提出的,，這位作者發(fā)現(xiàn)這個(gè)網(wǎng)站的使用者不太可能與來自不同種族背景的使用者互動(dòng)，即便這位作者控制了種族多樣性的地區(qū)差異之后也是如此,。
然而,，這組作者還發(fā)現(xiàn)，相對(duì)于發(fā)起一個(gè)跨種族的互動(dòng),，來自所有種族背景的使用者都同樣可能或者更可能對(duì)一個(gè)跨種族的消息做出回應(yīng),。此外，一旦使用者獲得了一個(gè)跨種族的消息,，他們就繼續(xù)發(fā)起進(jìn)一步的跨種族交流,，而不是像之前那樣。
這些結(jié)果提示,，與跨人群偏好的基準(zhǔn)率的預(yù)測(cè)相比,，人們更可能對(duì)跨種族界限的浪漫的姿態(tài)做出回報(bào)，而且一旦他們這樣做了,，他們就更可能發(fā)起跨種族的互動(dòng),。（生物谷Bioon.com）

The limits of racial prejudice
Kevin Lewis
The racial segregation of romantic networks has been documented by social scientists for generations. However， because of limitations in available data,， we still have a surprisingly basic idea of the extent to which this pattern is generated by actual interpersonal prejudice as opposed to structural constraints on meeting opportunities,， how severe this prejudice is， and the circumstances under which it can be reduced. I analyzed a network of messages sent and received among 126,，134 users of a popular online dating site over a 2.5-mo period. As in face-to-face interaction,， online exchanges are structured heavily by race. Even when controlling for regional differences in meeting opportunities， site users—especially minority site users—disproportionately message other users from the same racial background. However,， this high degree of self-segregation peaks at the first stage of contact. First,， users from all racial backgrounds are equally likely or more likely to cross a racial boundary when reciprocating than when initiating romantic interest. Second， users who receive a cross-race message initiate more new interracial exchanges in the future than they would have otherwise. This effect varies by gender,， racial background,， and site experience； is specific to the racial background of the original sender,； requires that the recipient replied to the original message,； and diminishes after a week. In contrast to prior research on relationship outcomes,， these findings shed light on the complex interactional dynamics that—under certain circumstances—may amplify the effects of racial boundary crossing and foster greater interracial mixing.
