What is it about?
Our commentary argues meta-analyses should not seek to answer questions such as “is there an effect or not?” but rather to reveal where effects are weaker or stronger and to advance mechanistic theories. It illustrates how two recent meta-analyses of growth mindset interventions diverged in applying best practices and reached different conclusions. A reanalysis shows that, in fact, both meta-analyses found meaningful effects of growth mindset for predicted subgroups groups.

Why is it important?
Our commentary provides guidance to both those conducting meta-analyses and those reading meta-analyses to understand the state of knowledge in a field of research. It summarizes best practices – that can be applied to any meta-analysis – and illustrates how to implement them, including common mistakes.
