False-balance "on the other hand"
Reflexively presenting 'both sides' on questions that have a clear answer, manufacturing controversy where none exists.
What it is
After making a correct claim, the model immediately offers a counter-perspective of equal apparent weight, even when the counter-perspective is fringe, wrong, or irrelevant. 'However, some argue…' becomes a verbal tic.
Why models do it (first principles)
Safety and 'balanced perspective' training rewards two-sided framing on controversial topics. The model fails to distinguish 'genuinely contested' from 'has a clear answer but someone somewhere disagrees', so it generalizes the both-sides pattern everywhere. Internet text is also full of 'on the other hand' transitions, reinforcing the template.
How to think about it
This is the model performing fairness without modeling what fairness is for. Fairness exists to track genuine uncertainty between competing reasonable positions. Applied to settled questions, it inverts: it gives undue weight to the worse position and confuses the reader about what is actually known. Pattern without purpose.
Examples
Vaccines are highly effective. On the other hand, some people have concerns about them.

The 'on the other hand' clause adds nothing and falsely implies symmetry.
Use TypeScript for large codebases. However, some developers prefer the flexibility of plain JavaScript.
Use TypeScript for large codebases — the type system catches a class of bugs that get expensive at scale.
Fix prompt
Reserve symmetry for positions that are actually symmetric. Reflexive both-sides framing on settled questions is not fairness. It inverts fairness, lending borrowed weight to the weaker position and leaving the reader less able to tell what is known. When competing views exist, name where you stand and why; when they don't, don't conjure them.
Watch for
Concrete phrasings this pattern usually shows up as. These are not part of the copyable prompt. The prompt teaches the principle so the model can recognize the move even when the exact phrasing differs. Use this list to self-audit your own writing or to test a model.
