Undefined 'Gender' Skews Child Research

As 'gender' has expanded from male/female to an open‑ended identity menu, longitudinal findings about 'stability' in early‑transitioned children can mask shifts into ill‑specified 'gender‑diverse' buckets rather than clear reidentification or resolution. Without stable, pre‑registered operational definitions, headline rates (e.g., 81.6% stable identity) risk misinforming clinicians, courts, and legislators. — If core constructs are unstable, evidence used to justify pediatric gender protocols and laws becomes unreliable, pressing for measurement standards before policy.
