The effectiveness of a combined cognitive bias correction and scientific reasoning approach to reducing misinformation engagement

The growing spread of conspiracy theories and misinformation has prompted research into strategies to curb their spread. These strategies often involve inoculation techniques or nudging, with one effective method being the Scientific Reasoning Intervention (SRI), which fosters critical scientific appraisal skills. We examined whether adding a broader focus on correcting cognitive biases, known as Cognitive Bias Correction (CBC), derived from metacognitive training (MCT) could further enhance the effectiveness of SRI. A total of 151 participants were randomly assigned to one of three conditions: SRI + CBC, SRI-only, or control. A slight improvement was observed on misinformation engagement behaviours in the SRI + CBC group, relative to the SRI-only, or control groups. Our study illustrates the potential benefits in combining different inoculation techniques. Specifically, that targeting scientific reasoning and cognitive biases in combination may help reduce engagement with misinformation.
