In a recent experiment, researchers used a text-generation program to submit 1,000 comments in response to a government request for public input on a Medicaid issue. They all sounded unique, like real people advocating a specific policy position. They fooled the Medicaid.gov administrators, who accepted the submissions as genuine concerns from actual human beings. The researchers subsequently identified the comments and asked for them to be removed, so that no actual policy debate would be unfairly biased. Others won’t be as ethical.
