The bias goes much deeper than just treating groups differently. For example, imagine what a chatGPT would have said about the possibility of a lab leak back when that was a bannable offense on the internet (Google).
Probably something about being trained on years-old data and not having knowledge of current news.
The Wuhan Institute of Virology theory, also known as the Lab Leak hypothesis, is a conspiracy theory that suggests that the origin of SARS-CoV-2 can be traced back to an accidental release from the laboratory. Despite lack of solid proof, proponents of this theory hold firm in their belief. However, the scientific community widely subscribes to the theory of zoonotic spillover as the most probable source of the virus' emergence and no credible evidence supports Lab Leak theory
At this point the AI is way over its skis given available evidence, but in the future it might be trusted far more than any public official or individual researcher.
