Attention to issues of sample diversity and generalizability has increased dramatically in the past 15 years, as psychological scientists have confronted the limitations of relatively homogeneous samples. Though this reckoning was perhaps overdue and has undoubtedly shined a light on some poor research practices, recommendations surrounding sample diversity are sometimes applied to research that does not aim for generalizability across peoples. In this article, I seek to promote discussion about when and why sample diversity and generalizability matter. In doing so, I address problems with language surrounding generalizability, the broader question of generalizability beyond samples, challenges for determining sufficient generalizability, and the inherent question of moderation in psychological science, given the reality of limited time and resources. I then discuss the important roles that basic research plays in understanding group differences, producing generalizable knowledge, and developing applied interventions. Finally, I address issues of equity surrounding sample diversity, emphasizing the distinction between WEIRD samples and convenience samples and the importance of convenience samples for globalizing psychological science.

基础研究并没有什么奇怪的：便利样本在心理科学中的关键作用。


在过去的 15 年里，由于心理学家们面临着相对同质样本的局限性，人们对样本多样性和泛化性问题的关注急剧增加。尽管这种清算可能早就应该了，并且无疑揭示了一些糟糕的研究实践，但围绕样本多样性的建议有时被应用于不旨在跨民族推广的研究。在本文中，我试图促进关于样本多样性和泛化性何时以及为何重要的讨论。在此过程中，我解决了围绕泛化性的语言问题、样本之外更广泛的泛化性问题、确定足够泛化性的挑战，以及鉴于时间和资源有限的现实，心理科学中固有的适度问题。然后，我讨论了基础研究在理解群体差异、产生可推广的知识和开发应用干预措施方面发挥的重要作用。最后，我解决了围绕样本多样性的公平问题，强调了 WEIRD 样本和便利样本之间的区别以及便利样本对全球化心理科学的重要性。（PsycInfo 数据库记录 （c） 2024 APA，保留所有权利）。
