Autism beliefs are partisan

Americans split sharply by party on what causes autism: 68% of Republicans vs 34% of Democrats say a mother’s medication use contributes, and 44% of Republicans vs 15% of Democrats cite childhood vaccines. Even after an official warning about acetaminophen, only 18% see it as a high pregnancy risk. — Partisan sorting on biomedical causation complicates health guidance and indicates that scientific debates are becoming political identity markers.
