RETRACTED ARTICLE: High replicability of newly discovered social-behavioural findings is achievable - Nature Human Behaviour
Abstract Failures to replicate evidence of new discoveries have forced scientists to ask whether this unreliability is due to suboptimal implementation of methods or whether presumptively optimal methods are not, in fact, optimal. This paper reports an investigation by four coordinated laboratories of the prospective replicability of 16 novel experimental findings using rigour-enhancing practices: confirmatory tests, large sample sizes, preregistration and methodological transparency.
Do Obligations Follow the Mind or Body?
Abstract Do you persist as the same person over time because you keep the same mind or because you keep the same body? Philosophers have long investigated this question of personal identity with thought experiments. Cognitive scientists have joined this tradition by assessing lay intuitions about those cases. Much of this work has focused on judgments of identity continuity. But identity also has practical significance: obligations are tagged to one's identity over time.

ILLUSTRATION: KATTY HUERTAS With 2020 finally behind us, we can begin to think about how the historic events that took place will be understood in years to come. To do so, we asked young scientists this question: What new word or phrase would you add to the dictionary to help scientists explain the events of 2020 to future generations?

Kids these days: Why the youth of today seem lacking
Abstract In five preregistered studies, we assess people’s tendency to believe “kids these days” are deficient relative to those of previous generations. Across three traits, American adults (N = 3458; Mage = 33 to 51 years) believe today’s youth are in decline; however, these perceptions are associated with people’s standing on those traits.

Context Moderates Affirmation Effects on the Ethnic Achievement Gap
We attempted to replicate a self-affirmation intervention that produced a 40% reduction in the academic achievement gap among at-risk students. The intervention was designed as a protection against stereotype threat—, which creates stress and suppresses the performance, engagement, and learning of students stereotyped as intellectually inferior.
