Laughing Through the Myths: Using Satirical Humor to Counter Misinformation About Contraceptives on Social Media
The rise of health-related misinformation on social media has caused many young women to shift from hormonal methods to natural contraceptive options. This study examines the effectiveness of satirical corrections in countering misinformation about contraceptives on TikTok. A total of 678 Dutch-speaking women aged 18-35, either watched TikTok videos containing misinformation about contraception followed by (1) no correction, (2) a non-humorous co…
Combatting the Misinformation Crisis: A Systematic Review of the Literature on Characteristics and Effectiveness of Media Literacy Interventions
Due to the prevalence of misinformation in current media environments, there is an urgent need for effective media literacy interventions that broadly protect people from its negative effects. However, such interventions do not always have their desired impact, calling for a better understanding of the factors influencing their efficacy. Therefore, we conducted a systematic literature review on 80 experimental studies, following the PRISMA checkl…
Combatting the persuasive effects of misinformation: Forewarning versus debunking revisited
We posit that research into misinformation interventions puts too much focus on informational outcomes (e.g. perceived accuracy of misinformation), and too little on persuasive outcomes (e.g. inferred beliefs, attitudes, intentions, and behaviors). Because of the informational outcome focus, common misinformation interventions (i.e. forewarning and debunking) have not been systematically tested for their ability to mitigate persuasive effects. In…
Direct Replication in Experimental Communication Science: A Conceptual and Practical Exploration
Replication is generally considered a keystone of the scientific enterprise. Unfortunately, in communication science, there is a lack of clarity on what a replication actually entails, and to what extent replicators may deviate from original studies. In order to support researchers in conducting, evaluating, and justifying the setup of replications of communication science experiments, we provide a taxonomy of replication types. We argue that res…
Continued influence of misinformation in times of Covid ‐19
Health‐related misinformation, especially in times of a global health crisis, can have severe negative consequences on public health. In the current studies, we investigated the persuasive impact of COVID‐19‐related misinformation, and whether the valence of the misinformation and recipients' degree of overconfidence affect this impact. In two pre‐registered experimental studies, participants ( N = 403; N = 437) were exposed to either a positive …
Questionable Research and Publication Practices in Communication Science
According to Thomas Kuhn, scientific revolutions always take place in response to anomalous data: When data are presented that do not concur with an established paradigm, the paradigm will shift. W
Blinded by the Light: How a Focus on Statistical “Significance” May Cause p -Value Misreporting and an Excess of p -Values Just Below .05 in Communication Science
Publication bias promotes papers providing “significant” findings, thus incentivizing researchers to produce such findings. Prior studies suggested that researchers’ focus on “p .05 (88.3%) or vice versa (11.7%). Analyzing p-value frequencies just below .05 using a novel method did not unequivocally demonstrate “p-hacking”—excess p-values could be alternatively explained by (severe) publication bias. Results for 19,830 p-values from social psycho…
Breakthrough or One-Hit Wonder: Three Attempts to Replicate Single-Exposure Musical Conditioning Effects on Choice Behavior
Three studies replicated a classroom experiment on single-exposure musical conditioning of consumer choice ( Gorn, 1982 ), testing whether simultaneous exposure to liked (vs. disliked) music and a pen image induced preferences for the shown (vs. a different) pen. Experiments 1 and 2 employed the original music, Experiment 3 used contemporary music. Experiments 2 and 3 employed hypothesis-blind experimenters. All studies incorporated post-experime…
The Language of Extraversion: Extraverted People Talk More Abstractly, Introverts Are More Concrete
To understand the impact of personality, one needs to know how personality differences manifest themselves in language use. The present study investigates the link between extraversion and language abstraction. Participants' spontaneous verbal utterances in face-to-face interactions were analyzed for language abstraction by applying the linguistic category model, which distinguishes predicate types that convey information in concrete or interpret…
It Is All About Being Popular: The Effects of Need for Popularity on Social Network Site Use
Prior research on predictors of social network site (SNS) use has mainly focused on the Big Five, narcissism, and self-esteem. Results have been inconsistent, and variance explained was rather low. Need for popularity (NfP) might be a better predictor of SNS use, because SNSs are ideal venues for people with a high NfP. Study 1 tested NfP, self-esteem, need to belong, entitlement, and vanity as predictors for a range of SNS behaviors; Study 2 rep…
Forecasting the Experience of Future Entertainment Technology: Interactive Storytelling” and Media Enjoyment
Advances in gaming and other entertainment technologies are evolving rapidly and create new conceptual challenges for understanding and explaining the user experiences they can facilitate. The present article reports a prospective study on a particularly promising entertainment technology of the future: Interactive storytelling (IS). Integrating various streams of computing technology, such as advanced visualization, natural speech processing, an…

How terrorism news reports increase prejudice against outgroups: A terror management account
Three studies tested predictions derived from terror management theory (TMT) about the effects of terrorism news on prejudice. Exposure to terrorism news should confront receivers with thoughts about their own death, which, in turn, should increase prejudice toward outgroup members. Non-Muslim (Studies 1–3) and Muslim (Study 3) participants were exposed to news about either Islamic terrorist acts or to control news. When Dutch filmmaker Theo van …

A Logical Toolkit for Theory (Re) Construction
The social sciences have achieved highly sophisticated methods for data collection and analysis, leading to increased control and tractability of scientific results. Meanwhile, methods for systematizing these results, as well as new ideas and hypotheses, into sociological theories have seen little progress, leaving most sociological arguments ambiguous and difficult to handle, and impairing cumulative theory development. Sociological theory, cont…
