inoculation
Definition
Inoculation refers to a pre-emptive psychological intervention that exposes individuals to weakened forms of misinformation or manipulative techniques before they encounter such content directly, building cognitive resistance in the same way that a vaccine primes the immune system. The intervention typically consists of two components: a threat component that forewarns recipients of an imminent persuasive attack, and a refutational pre-emption that supplies the cognitive tools needed to identify and reject misleading content. Inoculation can target specific false claims or the broader rhetorical techniques underlying misinformation, with the latter approach offering greater scalability across topics and populations. Applied to pro-Kremlin disinformation among Germans with a Russian migration background, inoculation significantly improved participants' ability to detect false narratives and reduced their perceived credibility, while also strengthening solidarity with Ukraine, and these effects held regardless of participants' Russian identity or Russian media consumption. Against conspiracy theories, inoculation-based interventions reduced susceptibility to implausible theories and lowered epistemically unwarranted beliefs, though they did not improve critical appraisal of plausible theories and carried some risk of promoting indiscriminate scepticism.

Applications
Inoculation and Social Cues
Persuasive social cues, such as fabricated likes and shares, increase the perceived reliability and accuracy of misinformation even among individuals who have received an inoculation intervention. However, the protective effect of inoculation remains consistent across social cue conditions, meaning that social endorsement of misinformation does not diminish the intervention's efficacy.

Inoculation and Social Identity
Having a Russian identity and consuming Russian media predicts heightened susceptibility to pro-Kremlin disinformation, suggesting that identity-related motivations can constitute a meaningful vulnerability. Inoculation effects on disinformation susceptibility were not significantly moderated by Russian identity, indicating that the intervention performs equally well for high-risk identity groups as for the general population.

Inoculation and Discernment
Inoculation-based interventions reduce belief in implausible conspiracy theories and lower epistemically unwarranted beliefs, but they do not improve participants' ability to critically evaluate plausible conspiracy theories. A dedicated discernment intervention, which explicitly discouraged blind scepticism, was more effective at improving accurate appraisal of both plausible and implausible theories, a distinction the research treated as a meaningful limitation of standard inoculation approaches.
