Should medical boards penalize doctors who give health advice that contradicts contemporary scientific consensus?

In 2022 lawmakers in the U.S. state of California passed legislation which empowered the state medical board to discipline doctors in the state who “disseminate misinformation or disinformation” that contradicts the “contemporary scientific consensus” or is “contrary to the standard of care.” Proponents of the law argue that doctors should be punished for spreading misinformation and that there is clear consensus on certain issues such as that apples contain sugar, measles is caused by a virus, and Down syndrome is caused by a chromosomal abnormality. Opponents argue that the law limits freedom of speech and scientific “consensus” often changes within mere months.
