The effectiveness of training interventions aimed at improving critical thinking to counter mis- and disinformation is the focus of this systematic review. While critical thinking is widely recognized as a crucial aspect, the authors state that more evidence is needed to identify which approaches are most effective.
Following PRISMA guidelines and a pre-registered protocol, the authors searched 12 databases and identified 8,041 articles. After screening and peer review, 17 studies were included. Most used true or quasi-experimental designs with moderate risk of bias and focused on media and information literacy through active learning approaches that included CT as part of the instruction.
Research results indicate an overall improvement in participants’ critical thinking, although not all interventions explicitly targeted or measured this competence. In the end, only seven studies fully met the eligibility criteria, and the heterogeneity of results limited firm conclusions about overall effectiveness.
The authors conclude by highlighting key elements for successful interventions, like active learning, diverse resources, and the explicit integration of critical thinking as a core objective within robust research designs.
