【 摘 要 】

Underpowered studies remain ubiquitous (Maxwell, 2004; Bakker et al., 2012; Button et al., 2013; Turner et al., 2013; Szucs and Ioannidis, 2017) despite strong pleas to change this practice (Cohen, 1988, 1990, 1992). As with any complex problem, multiple factors contribute to the ubiquity of conducting underpowered studies, and a wide range of efforts is needed to solve it. Most efforts to improve matters have focused on researchers and funding agencies. The present state of affairs evidences the unsuccessful education of both groups (e.g., Bakker et al., 2016). Therefore, in this contribution we propose to target next generations of researchers (i.e., students). We will briefly summarize the main reasons why underpowered research is a problem, discuss common defenses of underpowered studies, and then outline our proposed solutions.
