There is no psychology without inferential statistics.

Quantification has been constitutive of psychology since its inception and is core to its scientific status. The adoption of qualitative methods eschewing inferential statistics is therefore unlikely to obtain. Rather than discarding useful tools because of improper use, we recommend highlighting how inferential statistics can be more thoughtfully applied.

A legend in one's own mind: The link between ambition and leadership evaluations.

Individuals who have more ambition-a persistent striving for success, attainment, and accomplishment-are more likely to become leaders. But are these ambitious individuals also more effective in leadership roles? We hypothesize that leader ambition is related to positive self-views of leader effectiveness that remain uncorroborated by relevant third-party actors. In a multiwave, preregistered study, we find evidence for this hypothesis using a sample of executives (N = 3,830 ratings of 472 leaders) who were rated by peers, subordinates, managers, and themselves on ten leadership competencies, including their ability to motivate others, manage collaborative work, coach and develop people, and present and communicate ideas. We consider the implications of our findings for both scholars and practitioners interested in leadership selection and development.

Strategic Mindsets and Support for Social Change: Impact Mindset Explains Support for Black Lives Matter Across Racial Groups.

How does the self-relevance of a social movement shape individuals' engagement with it? We examined the decision-making processes that underlie support for Black Lives Matter (BLM) among Black, Hispanic, Asian, and White Americans. We find significant between-group differences in levels of support for BLM, both in terms of past behavior (Study 1) and in terms of future intentions to support the movement (Study 2). These differences notwithstanding, thinking about how one's decisions impact others - which we label impact mindset - explains support for BLM across racial groups, cross-sectionally as well as longitudinally (over 8 months later). Our findings underscore the equivalence of the impact mindset construct across racial groups and its predictive power in the context of BLM. We conclude that, although the struggle for racial justice has different meanings for different racial groups, the same mindset underlies both in-group advocacy and allyship in the context of BLM.

The replication crisis has led to positive structural, procedural, and community changes.

The emergence of large-scale replication projects yielding successful rates substantially lower than expected caused the behavioural, cognitive, and social sciences to experience a so-called 'replication crisis'. In this Perspective, we reframe this 'crisis' through the lens of a credibility revolution, focusing on positive structural, procedural and community-driven changes. Second, we outline a path to expand ongoing advances and improvements. The credibility revolution has been an impetus to several substantive changes which will have a positive, long-term impact on our research environment.

Teaching open and reproducible scholarship: a critical review of the evidence base for current pedagogical methods and their outcomes.

In recent years, the scientific community has called for improvements in the credibility, robustness and reproducibility of research, characterized by increased interest and promotion of open and transparent research practices. While progress has been positive, there is a lack of consideration about how this approach can be embedded into undergraduate and postgraduate research training. Specifically, a critical overview of the literature which investigates how integrating open and reproducible science may influence student outcomes is needed. In this paper, we provide the first critical review of literature surrounding the integration of open and reproducible scholarship into teaching and learning and its associated outcomes in students. Our review highlighted how embedding open and reproducible scholarship appears to be associated with (i) students' scientific literacies (i.e. students' understanding of open research, consumption of science and the development of transferable skills); (ii) student engagement (i.e. motivation and engagement with learning, collaboration and engagement in open research) and (iii) students' attitudes towards science (i.e. trust in science and confidence in research findings). However, our review also identified a need for more robust and rigorous methods within pedagogical research, including more interventional and experimental evaluations of teaching practice. We discuss implications for teaching and learning scholarship.
