Review
In the article, "Disentangling Item and Testing Effects in Inoculation Research on Online Misinformation: Solomon Revisited" (2021), Roozenbeek, Maertens, McClanahan, and van der Linden address methodological questions about the effectiveness of the "Bad News" game, an online fake news inoculation tool. The authors investigate the potential item and testing effects, which may influence the observed intervention effects. Their study, based on two online experiments with a total of 2,159 participants, showed that while item effects somewhat influenced inoculation interventions, testing effects did not.
The researchers found that inoculation interventions were effective at improving people's ability to identify misinformation techniques, without making them more skeptical of real news. These findings suggest that the "Bad News" game is a promising tool for building cognitive resistance against misinformation online. By examining the item and testing effects, this study provides valuable insights into the methodological issues in evaluating real-world psychological interventions.
