Roozenbeek, Maertens, McClanahan, and van der Linden’s 2021 study examines the methodological factors affecting the effectiveness of the “Bad News” game, an intervention designed to combat misinformation online. The study explores how item and testing effects influence the intervention’s outcomes and assesses its role in building resilience against misinformation.
Background
The “Bad News” game aims to enhance public resistance to misinformation by simulating the techniques used in spreading fake news. The researchers conducted two experiments with 2,159 participants to investigate how factors such as item-specific biases or testing-related influences might affect the interpretation of the intervention’s success. This work builds on the broader field of inoculation theory, which suggests that exposing individuals to a weakened form of misinformation can improve their ability to recognize and resist similar tactics in real-world contexts.
Key Insights
Item Effects: The research highlighted the presence of item effects, where specific question phrasing or content could influence participants' responses, potentially impacting the evaluation of the intervention's effectiveness.
- Effectiveness of the Game: The study demonstrated that the “Bad News” game effectively enhanced participants’ ability to identify misinformation techniques, while preserving their trust in legitimate news sources.
- Item Effects: The research highlighted the presence of item effects, where specific question phrasing or content could influence participants’ responses, potentially impacting the evaluation of the intervention’s effectiveness.
- Testing Effects: No evidence of testing effects was found, indicating that repeated exposure to the testing materials did not bias participants’ responses or artificially inflate results.
Significance
This study provides critical insights into the methodology of evaluating psychological interventions in real-world settings. By addressing item effects, the authors emphasize the need for rigorous experimental designs that account for such influences. The findings also underscore the “Bad News” game’s potential as a practical tool for countering misinformation while maintaining trust in credible information sources.
Future Directions
Future research could explore how the “Bad News” game performs across diverse cultural contexts and with varying demographics to ensure its broader applicability. Additionally, further studies may refine intervention strategies by reducing item biases and tailoring content to specific misinformation scenarios.
Conclusion
By examining the methodological factors affecting the “Bad News” game, this study contributes to the growing body of research on combating online misinformation. The findings highlight the game’s effectiveness in promoting media literacy while pointing to opportunities for refining its evaluation and implementation.

Modern Intelligence Testing: Principles and Practice
Intelligence testing has evolved significantly since Alfred Binet developed the first practical IQ test in 1905. Modern instruments like the Wechsler scales (WAIS-V for adults, WISC-V for children) and the Stanford-Binet Intelligence Scales (SB5) are built on decades of psychometric research, normative data collection, and factor-analytic refinement.
Key Takeaways
- Major IQ tests achieve internal consistency coefficients above 0.95 for composite scores and test-retest reliability above 0.90, making them among the most reliable instruments in all of psychology.

Contemporary IQ tests typically measure multiple cognitive domains organized according to the Cattell-Horn-Carroll (CHC) theory of cognitive abilities. Rather than producing a single number, they provide a profile of strengths and weaknesses across domains such as verbal comprehension, fluid reasoning, working memory, processing speed, and visual-spatial processing. This profile approach is more clinically useful than a single Full Scale IQ score, as it can identify specific learning disabilities, cognitive strengths, and patterns associated with various neurological conditions.
Test reliability — the consistency of measurement — is a critical quality indicator. Major IQ tests achieve internal consistency coefficients above 0.95 for composite scores and test-retest reliability above 0.90, making them among the most reliable instruments in all of psychology. However, reliability does not guarantee validity: ongoing research examines whether these tests adequately capture the full range of cognitive abilities valued across different cultures and contexts.
Implications for Test Users and Practitioners
These findings have direct implications for professionals who administer, interpret, or rely on cognitive test results. Clinicians should report confidence intervals alongside point estimates, use profile analysis to identify meaningful strengths and weaknesses rather than relying solely on Full Scale IQ, and consider the measurement properties of the specific subtests being interpreted. Score differences that fall within the standard error of measurement should not be over-interpreted as meaningful patterns.
For organizational contexts (educational placement, employment selection, forensic evaluation), understanding measurement properties helps prevent both over-reliance on test scores and inappropriate dismissal of their utility. The best practice is to integrate cognitive test results with other sources of information — behavioral observations, developmental history, academic records, and adaptive functioning — rather than making high-stakes decisions based on any single score.
Frequently Asked Questions
Does higher intelligence protect against misinformation?
Research shows a complex relationship. Higher cognitive ability is associated with better analytical thinking and detection of logical fallacies. However, intelligent individuals can also be more skilled at rationalizing beliefs they’re motivated to hold. Critical thinking skills and intellectual humility appear more protective than raw intelligence against misinformation susceptibility.
People Also Ask
What is interpreting differential item functioning with response process data?
Understanding differential item functioning (DIF) is critical for ensuring fairness in assessments across diverse groups. A recent study by Li et al. introduces a method to enhance the interpretability of DIF items by incorporating response process data. This approach aims to improve equity in measurement by examining how participants engage with test items, providing deeper insights into the factors influencing DIF outcomes.
