Generative AI and misinformation: a scoping review of the role of generative AI in the generation, detection, mitigation, and impact of misinformation - AI & SOCIETY
The rapid advancement of generative artificial intelligence (AI) has introduced both opportunities and challenges in the fight against misinformation. This scoping review synthesizes recent empirical studies to explore the dual role of generative AI—particularly large language models (LLMs)—in the generation, detection, mitigation, and impact of misinformation. Analyzing 24 empirical studies, our review suggests that LLMs can generate highly convincing misinformation, often exploiting cognitive biases and ideological leanings of the audiences, while also demonstrating the ability to detect false claims and enhance users’ resistance to misinformation. Mitigation efforts show mixed results, with personalized corrections proving effective but safeguards inconsistently applied. Additionally, exposure to AI-generated misinformation was found to reduce trust and influence decision-making. This review underscores the need for standardized evaluation metrics, interdisciplinary collaboration, and stronger regulatory measures to ensure the responsible use of generative AI in the information ecosystem.

I agree; if AI is used to polish and organize thoughts that’s fine. However it was clear several comments were directly generated by AI focusing on obscure technical issues that a generalist editor is unlikely to know.

We once got a desk reject from a top comm journal and the editor’s comments are clearly AI generated. Is that ethical?

Instead of directly correcting false claims, “bypassing” offers an alternative strategy: focus on positive, truthful statements about the same topic. New research suggests it can be very effective and I cover it in more detail here!

When it comes to statistical power, how is Communication Science doing? Sun, Shen, Pan, and Quan’s article: “Toward a More Powerful Experimental Communication Science: An Assessment of Two Decades’ Research (2001–2023)” gives an answer. In short, not so good: doi.org/10.1177/0093...
A bar chart displaying the reporting of statistical power analysis by year from 2001 to 2023. The Y-axis shows the percentage of studies per category within each year, ranging from 0% to 75%. The X-axis represents years from 2001 to 2023. The chart is divided into five categories listed on the right: “A Priori,” “Sensitivity,” “Observed,” “Mention Only,” and “No Mention.” A Priori: Reporting is sparse before 2010 but increases steadily after 2017, peaking near 25% in recent years. Sensitivity: Reporting is minimal and sporadic across all years. Observed: Reporting is consistent but moderate, fluctuating around 10–25%. Mention Only: Reporting is infrequent and fluctuates around 5–10%. No Mention: Initially dominant but decreases over time, particularly after 2010. The chart highlights a trend toward increased A Priori power reporting and a decline in studies making no mention of power analysis, indicating evolving research practices over time. Table 2 summarizes the results from power analyses by study design, showing statistical power (median and range) and the percentage of studies at different power levels. The table includes data for four designs: Within-subject (k = 41), Two-group (k = 98), Multi-group (k = 93), and 2 × 2 Factorial (k = 184). The table shows that within-subject designs generally achieve higher statistical power, especially at larger effect sizes, while two-group and multi-group designs often fall below acceptable power levels, particularly for small effects. 2 × 2 factorial designs vary, with reversal effects showing higher power than attenuation effects. Overall, achieving adequate power remains a challenge in many designs, highlighting the need for careful study planning.

In this new article in American Psychologist we respond to critics in detail and clarify two key points for the field;

(1) The prevalence of misinformation in society is substantial when properly defined.

(2) Misinformation causally impacts attitudes and behaviors.

We wrote about this at some length in our paper "Misinformation in and about science".

www.pnas.org/doi/10.1073/...
In addition, researchers commonly misstate or overstate the implications of their work (35). In concert with researchers, university press offices play a particularly important role in communicating science—but too frequently do so in ways that prioritize web traffic over accuracy. Sometimes spin is carried over from the journal article itself (36); other times, it is added in the press release. A biomedical report might omit important caveats, draw inappropriate extrapolations from mouse models, and exaggerate prescriptive implications. One analysis found that nearly a third of 525 papers in top obesity or nutrition journals make inappropriate causal claims in their abstracts or titles (37); in another study, roughly the same fraction of health-related papers widely shared on social media used inappropriately strong causal language (38). Some fields may be more prone to hype than others. A new result on the geometry of Banach spaces may be more difficult to hype than a bioweapon claim, but we surmise that most fields are susceptible. Much of this truth bending may be unnecessary. Most studies (39–41) fail to find an association between exaggeration and uptake by the news media. Admittedly, selection bias may play a role: perhaps the stories that are not exaggerated are those that do not need to be. In any case, high-quality press releases appear to drive higher-quality news stories on that research (42, 43).
