Thresholds Inflate Embryo Selection Benefits

Embryo‑selection risk claims often rely on the liability‑threshold model, which turns continuous traits into yes/no diseases. Small score‑driven shifts can push many people just below a cutoff, producing impressive relative 'risk reductions' that hide minimal real‑world change. For traits like obesity or type 2 diabetes, this can make modest phenotypic shifts look like dramatic cures. — This challenges how genetic services are marketed and regulated, urging clearer communication and standards so consumers and policymakers aren’t misled by dichotomy‑driven statistics.
