Why do people engage with similar others despite ample opportunities to interact with dissimilar others? We argue that adversity or setbacks may have a stronger deteriorative effect on ties made up of dissimilar individuals, prompting people to give up on such ties more easily, which, over the long run, results in people forming ties with similar others. We examine this argument in the context of Association of Tennis Professionals tournaments, using data on 9,669 unique doubles pairs involving 1,812 unique players from 99 countries from 2000 to 2020. We find that doubles pairs with players from different countries are more likely to dissolve after a setback, especially if those countries lack social trust and connections with one another; this reality further contributes to the individual player's increased tendency to collaborate with same-country players in the next tournament. Our study has direct implications for interventions for diversity and inclusion.

同质化、挫折和异质关系的解散：来自职业网球的证据

尽管有很多机会与不同的人互动，但为什么人们会与相似的人交往？我们认为，逆境或挫折可能会对由不同个体组成的关系产生更强的恶化影响，促使人们更容易放弃这种关系，从长远来看，这会导致人们与相似的人建立关系。我们在职业网球协会锦标赛的背景下研究了这一论点，使用了 2000 年至 2020 年间来自 99 个国家/地区的 1,812 名独特球员的 9,669 对独特的双打组合的数据。我们发现，与来自不同国家/地区的球员的双打组合更有可能在挫折，特别是如果这些国家之间缺乏社会信任和联系；这一现实进一步促进了个体玩家的 在下一届锦标赛中与同一国家/地区的球员合作的趋势增加。我们的研究对多样性和包容性的干预措施有直接影响。
