They don’t march in the streets or storm the polls, but a new breed of AI-controlled personas could be the next big threat to democracy.

According to a new policy forum paper in Science, Swarms of AI personas mimic humans so well they can infiltrate online communities, shape conversations, and tilt elections—all at machine speed.

About The Study: This cross-sectional analysis estimated that in 1990, 19.3% of the U.S. adult population were living with obesity; by 2022, this had increased to 42.5%. By 2035, this was forecasted to increase to 46.9%. There was substantial variation by state and race and ethnicity group, indicating large disparities in obesity prevalence. Differences in the prevalence of obesity by population group may be used to develop health policy and interventions to reduce inequities and the large burden of obesity in the U.S.
