Both updates increased negativity, loss framing and restoration desires (Replika negative posts, +24.7 percentage points, 95% CI 20.1 to 29.2; ChatGPT, +13.0 percentage points, 95% CI 10.8 to 15.2), with larger Replika (versus ChatGPT) increases in sadness (d = 2.67 versus 1.41) and negative mental health (d = 1.72 versus 0.63).

Drawing on recent empirical literature, we show how such systems can place disproportionate pressure on early-career researchers by incentivizing safe, tractable and easily evaluated outputs. Structural academic mechanisms such as peer review and funding, escalating publication costs and institutional inequalities interact with precarious employment and hierarchical dependencies. In this environment, we contend that strategic conformity becomes a rational career path. This risks suppressing creativity and critical thinking precisely at the stage when scientific independence could otherwise emerge. Consequently, the probability of substantive contributions by early-career researchers is declining, while talent may increasingly abandon academia or cluster within a limited number of well-resourced institutions and national systems. By adopting a systems-level perspective, we argue that scientific creativity is not merely an individual trait but an emerging property of a supportive academic landscape and that maintaining or restoring it may require substantial structural reforms. These include promoting stable research pathways, decentralized decision-making and evaluation frameworks that better recognize collaboration, originality, persistence and nonlinear career trajectories. Without systemic change, we risk stifling the potential of early-career researchers to go beyond the confines of existing methods and approaches and deliver transformative advances. This would limit their capacity to meaningfully change our understanding of the world or benefit society, with impacts that fall short of their potential.</p>","PeriodicalId":19074,"journal":{"name":"Nature Human Behaviour","volume":" ","pages":""},"PeriodicalIF":17.5,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148888186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using two nationally representative US longitudinal datasets (the High School Longitudinal Study, n = 6,340; and the Baccalaureate and Beyond Class of 2016, n = 12,950), we estimate relative representation across majors spanning male-majority physics/engineering/computer science to female-majority health fields. Across datasets, representation is most polarized among lower-achieving students, particularly in male-majority fields, where lower-achieving straight-cisgender males are overrepresented relative to lower-achieving straight-cisgender females (relative ratio, 2.62; 95% confidence interval, 2.29-3.00), while this representation gap is smaller among higher-achieving students (P < 0.001). The patterns persist after adjusting for achievement, coursework, interests and aspirations. In female-majority fields, evidence for analogous in-group benefits is mixed across models vis-à-vis LGBTQ+ identity.
