False equivalence
Also called false balance, both-sidesing
Treating two things as equal (equally bad, equally likely, equally supported) when they aren't.
Fairness means hearing both sides; false equivalence means pretending the sides weigh the same when the evidence doesn't. It shows up as 'one expert for, one against' on a question where most experts agree, or 'they're all as bad as each other' when the scale differs. Studies show balanced-looking coverage makes people underestimate real expert agreement, and that simply stating the weight of evidence helps. This isn't a rule that one side is always right: sometimes things really are equal.

Ask: equal in what way, and by how much? Look for the size, not just the category.
