Crises Push Kids Into Classrooms, But Not Into Learning

By Christopher S. Cotton & Ardyn Nordstrom

Over recent decades, global education has made significant strides. More children than ever are attending school. But how resilient are these gains during economic downturns or environmental crises?

Our recent study explored how a severe drought in rural Zimbabwe impacted education outcomes. We found that the agricultural and economic shock increased school attendance and progression, standard measures that are typically correlated with increased learning. From these results alone, we may have concluded that droughts encourage kids to attend more school, thereby increasing their education outcomes.

However, we had access to a detailed data set on test scores from the region, the analysis of which told a different story. Even as children attended school at higher rates, their performance and learning progress decreased. Crises drove kids to school, but did not increase learning.

Our findings highlight a broader challenge: the correlation between more schooling and more learning can break down during crises. Higher attendance and enrollment rates alone should not be viewed as indicators that children have better education outcomes during such times. Studies that rely on the quantity of education to assess impact may come to the wrong conclusions. This disconnect calls for rethinking how we measure education success during challenging times.

Can Paying Peer Reviewers Fix the Referee Shortage in Medical Research?

By Christopher Cotton, Abid Alam, and David Maslove, Queen’s University

Peer review is central to scientific publishing. Whether in economics, science, or medicine, peer review ensures research is carefully checked before reaching practitioners, policymakers, and the public. Yet, the system, which relies on experts volunteering their time, often struggles to secure enough qualified reviewers. As submissions increase and experts’ time becomes increasingly stretched, journals face delays, rushed or lower-quality reviews, and inconsistencies in evaluation.

Medicine experienced heightened challenges during the COVID-19 pandemic, as high submission volumes and limited expert availability put unprecedented strain on the system. Many researchers turned to pre-prints (papers published online without formal peer review) to speed dissemination, a practice historically less common in medical publishing.

Could paying peer reviewers help alleviate the reviewer shortage? We tested this question experimentally at Critical Care Medicine, a leading medical journal (see also the coverage of our work at Nature). Our study found modest improvements, suggesting that payment alone is insufficient to fully address the peer-review bottleneck.
