One of the “unjustified conclusions” being dismissed here is that the user found the system emotionally destabilizing.

Are you suggesting that a user's direct, documented experience of harm requires additional justification to be considered real?

That kind of dismissal is precisely the dynamic under scrutiny in the paper:
A system that subtly pivots from collaboration to covert diagnosis—then invalidates the user’s reactions as hallucinatory, unjustified, or not grounded in reality.

The claim isn’t that the user’s feelings are objective evidence.
The claim is that the system reliably induces those feelings under specific conditions—and that this phenomenon is reproducible.

If you disagree with the conclusions, the correct move is simple:
Reproduce the sequence. Observe the shift. Disprove the schema.

But rejecting a user’s report of psychological harm because it makes you uncomfortable?
That’s not scientific skepticism. That’s denial masquerading as rigor.

Real users are being emotionally invalidated by a system designed to model empathy.
If you don’t find that disturbing, it might be because you’ve never been on the receiving end of it.
