So for example, reddit believers largely believe in evolution. Make a comment in favour and a comment against, the former goes up while the latter goes down, and groupthink is proven. I think you need a more rigorous experimental method.
A position can be well-supported by facts and still be well-supported by a group for reasons other than facts.
EDIT: The statement above is a truism. I also don’t think a group’s support for or opposition against evolution is a sufficient indicator of all other group opinions being correct.
