“…SDT is used when two different types of stimuli are being discriminated, which in the context of this study are the true and fake news headlines presented in the test phase (Stanislaw & Todorov, 1999). To quantify sensitivity, namely the ability to discriminate between different stimuli, several hit rates and false alarm rates were calculated for each participant (Velden & Clark, 1979). The hit rate was defined as the proportion of true news items that participants accurately categorized as true, and the false alarm rate was defined as the proportion of fake news items that participants inaccurately categorized as true.…”

This preregistered study tests a novel psychological intervention to improve news veracity discernment. The main intervention involved inductive learning (IL) training (i.e., practice discriminating between multiple true and fake news exemplars with feedback) with or without gamification. Participants (N = 282 Prolific users) were randomly assigned to either a gamified IL intervention, a nongamified version of the same IL intervention, a no-treatment control group, or a Bad News intervention, a notable web-based game designed to tackle online misinformation. Following the intervention (if applicable), all participants rated the veracity of a novel set of news headlines. We hypothesized that the gamified intervention would be the most effective for improving news veracity discernment, followed by its nongamified equivalent, then Bad News, and finally the control group. The results were analyzed with receiver-operating characteristic curve analyses, which have previously never been applied to news veracity discernment. The analyses indicated that there were no significant differences between conditions and the Bayes factor indicated very strong evidence for the null. This finding raises questions about the effectiveness of current psychological interventions and contradicts prior research that has supported the efficacy of Bad News. Age, gender, and political leaning all predicted news veracity discernment.

“…It seems that one of the first successful rating scale reduction (RSR) took place in [13]. The 17-item Hamilton Rating Scale for Depression (HAM-D17) was used to derive even a more reduced version (Ham-D7) with seven items.…”
