Personality feedback is one of the most common tools in leadership development and coaching. A systematic review finds only 12 studies examining whether it actually improves performance, and the evidence for causal benefit remains unestablished.
Cognitive ability tests are a staple of graduate recruitment. A 2023 critical review finds that the validity evidence used to justify them has been overstated, their adverse impact is real and consequential, and their use in high-volume screening raises questions that the field has been too slow to confront.
Conscientiousness is one of the most trusted predictors in personnel selection. A 2023 meta-analytic review finds that barely 12 percent of the supporting research was conducted under realistic hiring conditions, leaving the real-world validity of the measure more uncertain than its reputation suggests.
Game-based assessments promise to make hiring more engaging while measuring the same things as traditional tests. A 2024 study finds the validity case is reasonable, but the engagement promise is not: applicants actually reacted more negatively to the game format, especially those without much gaming experience.

Is there a real connection between physical attractiveness and personality? A 2026 study replicates and extends earlier findings, using longitudinal data to examine whether the two are more meaningfully linked than most people assume.
What is the best way to measure how cognitively demanding a job is? A 2023 study argues the answer might be simpler than we thought: just look at the average intelligence of the people doing it.
Growth Mindset Interventions: What Does the Evidence Actually Show? Growth mindset programs have spread through classrooms worldwide on the promise of large gains in student achievement. A rigorous 2022 meta-analysis of 97,000 students suggests the evidence behind that promise is far thinner than advertised.Growth mindset programs have spread through classrooms worldwide on the promise of large gains in student achievement.

The Problem The study of wisdom in psychology has long suffered from a curious irony: the field itself has lacked the very
In previous blogs, we discussed the benefits of boxing for trauma, depression, and mental resilience. We have also reviewed studies examining the impact of exercise on general well-being, noting that boxing is one of the few modalities shown to benefit those recovering from mental health issues. A recent study by Bozdarov et al. (2022) adds further weight to this growing body of evidence. The paper reviews existing research on boxing as a mental health intervention. In this article, we summarise the study and outline its most important findings.
