Is the past decade's spike in trans-identifying youth an authentic response to long suppressed identities or social contagion? 👧 That's the question evolutionary biologist Dr. Colin Wright took on in a 2025 article for the Wall Street Journal. One explanation often cited by media and activists, rests on a comparison to left-handedness. It claims that transgenderism isn’t rising, it’s just becoming more visible, the same way left-handed rates climbed once schools stopped forcing kids to switch hands. The article explains that innate traits should rise once accepted, then plateau, not spike and crash.  However, the data increasingly suggests a crash. Campus survey analysis found trans identification among college students fell 50% between 2023 and 2025, and separate national survey data shows an almost identical decline among 18-22 year-olds over the same window. 📉 Wright argues that even supposed “increases” don’t actually support their claim. Any growth is overwhelmingly in "nonbinary" labels like "genderfluid" and "demiboy.” These identities have no physical, measurable marker at all. Left-handedness is anatomical. This isn't. 🚫 As Wright puts it: "The surge in transgender identification in recent years wasn't the revelation of a hidden biological truth. It was a social phenomenon shaped by imitation, ideology and institutional reinforcement."
