Any psychologist in the course of his or her professional career will affect thousands of lives. It stands to reason then that the training of psychologists is, in its own way, a systems-level intervention with tremendous social impact. In the ideal world, training, like other interventions, would be grounded in evidence. But what exactly do we know about the science of training? Elsewhere in this same issue, we address that question by providing a literature review of empirically-grounded, evidence-based studies pertaining to: (a) admissions, curriculum, and research training (Callahan & Watkins, 2018a); (b) prepracticum and practicum training (Callahan & Watkins, 2018b); and (c) supervision, competency, and internship training (Callahan & Watkins, 2018c). In this opening commentary to that series of articles, we conceptualize training as a systems-level intervention that is perhaps the most impactful intervention available to our field. We provide a rationale for our evidence-based training-focused literature review and an overview of our search methods herein. We provide commentary on perceived barriers to evidence-based training and identify tribalism as being particularly pernicious to this perspective. We argue that data, not tribalism, should drive educational decisions and actions, particularly given that training significantly impacts our discipline and the public it serves.

循证培训：时机已到。

任何心理学家在其职业生涯中都会影响数千人的生命。因此，心理学家的培训按其自身的方式是一种具有巨大社会影响的系统级干预，这是理所当然的。在理想的世界中，培训与其他干预措施一样，将以证据为基础。但是我们对训练科学到底了解多少呢？在同一问题的其他地方，我们通过提供有关以下方面的以经验为基础的循证研究的文献综述来解决这个问题：(a) 招生、课程和研究培训 (Callahan & Watkins, 2018a)；(b) 实习前和实习培训 (Callahan & Watkins, 2018b)；(c) 监督、能力和实习培训 (Callahan & Watkins, 2018c)。在该系列文章的开篇评论中，我们将培训概念化为一种系统级干预，这可能是我们领域中最具影响力的干预。我们为我们以循证培训为重点的文献综述提供了基本原理，并在此概述了我们的搜索方法。我们对循证培训的感知障碍提供评论，并确定部落主义对这一观点特别有害。我们认为，数据而非部落主义应该推动教育决策和行动，特别是考虑到培训显着影响我们的学科和它所服务的公众。我们对循证培训的感知障碍提供评论，并确定部落主义对这一观点特别有害。我们认为，数据而非部落主义应该推动教育决策和行动，特别是考虑到培训显着影响我们的学科和它所服务的公众。我们对循证培训的感知障碍提供评论，并确定部落主义对这一观点特别有害。我们认为，数据而非部落主义应该推动教育决策和行动，特别是考虑到培训显着影响我们的学科和它所服务的公众。
