Large study debunks the idea that ADHD brains mature more slowly

A new analysis of the ABCD longitudinal dataset (11,000+ youths) shows that the long-standing claim that brains of kids with ADHD mature more slowly is likely a mirage. When researchers accounted for sex differences in how boys’ and girls’ brains develop over time, the previously observed link between ADHD and delayed cortical thinning disappeared. The finding suggests ADHD remains a biological condition with genetic components, but that early brain-imaging signals lacked reliable diagnostic biomarkers and highlighted replication challenges in neuroscience.

Rising Tide of Scientific Fraud Threatens Research Integrity

Scientific fraud has become a significant issue, with problems ranging from fabricated data in prestigious journals to fake papers from paper mills. The main causes include perverse incentives, power imbalances, and lack of oversight, leading to a culture where misconduct is common and often overlooked. This crisis undermines trust in scientific research, necessitating reforms such as stricter peer review, better oversight, and a cultural shift towards transparency and accountability.

"Psychology Protocol Boosts Research Reproducibility with 86% Success Rate"

Four research groups in the field of experimental psychology successfully replicated each other's work by following best practices, achieving an 86% success rate. The study, published in Nature Human Behaviour, demonstrates that research in the field can be of top quality if rigorous steps, such as preregistration of study protocols, are taken. The projects addressed serious research questions in various fields of social science, and the results suggest that these findings could apply to psychology more broadly. This effort aims to restore the reputation of experimental psychology and demonstrate that not all social sciences are inherently flawed.
