A really comprehensive roundup:
In 2018, a physician and researcher named Lisa Littman published a paper in the journal PLOS One describing what she termed “rapid-onset gender dysphoria” (ROGD). She hypothesized that some young people—particularly those assigned female at birth—might claim a transgender identity after increasing their social media use or befriending trans peers. According to this perspective, online platforms supposedly “infect” teenagers with the idea that they are trans, creating clusters of youth who suddenly identify in new ways.
From the moment Littman’s paper appeared, researchers and advocacy groups criticized its methodology. Littman’s survey collected responses solely from parents recruited on three websites openly skeptical or critical of medical care for trans youth. These anti-trans or “trans-skeptical” forums—4thWaveNow, Transgender Trend, and Youth Trans Critical Professionals—advertised Littman’s survey to parents who already believed their child’s trans identity was misguided. Unsurprisingly, 76.5% of respondents felt their child was “incorrect” in identifying as transgender.
Critics also pointed out that the youth themselves were never surveyed. Parents who participated were asked to diagnose their children with gender dysphoria (a clinical term referring to distress due to a mismatch between one’s internal sense of gender and assigned sex at birth), even though most parents do not have training in psychology or medicine.

Although Littman’s original 2018 article used the term ROGD, many discussions in conservative blogs and online groups substituted or conflated it with “transgender social contagion.” This idea claims that trans identity spreads from teen to teen like a virus—an online trend rather than a real expression of self.
While the ROGD paper didn’t use the “social contagion” phrase outright, it alluded to the concept through references to “peer influence” and social media immersion. Almost immediately, these concepts were embraced by anti-trans activists, policymakers, and media personalities. The theory gave them a sort of “scientific” veneer to argue that trans kids are just “confused.” As a result, many now simply refer to both ROGD and “transgender social contagion” interchangeably, even though they are (at least in Littman’s framing) slightly different.
