DARVO is the shape a conversation takes when raising something becomes the offence.
[1]What it looks like in an online argument
It is easier to recognise as a sequence than as a single message:
- Deny — it did not happen, or not like that, or it was a joke
- Attack — you are obsessive, dishonest, unstable, or running a vendetta
- Reverse victim and offender — you are the one harassing them, and they are being persecuted for something trivial
By step three the original conduct has left the conversation entirely, and the question in front of any audience is whether you have behaved acceptably.
Why it is effective
It exploits the fact that onlookers usually arrive late. Someone joining at step three sees a person being publicly accused, defending themselves, and describing distress. That reads as sympathetic, and reconstructing what actually started it takes effort nobody watching is obliged to make.
It also creates a genuine cost to continuing. Pressing the point now looks like piling on, so the cheapest option for you is to drop it — which is the outcome the pattern produces.
A caution worth taking seriously
This is one of the easiest concepts on this site to misuse.
The three components — denial, counter-accusation, claiming to be wronged — are also exactly what an innocent person does when accused of something they did not do. There is no way to tell the two apart from the structure alone, and anyone who tells you otherwise is selling certainty that does not exist.
So it is a lens for understanding why a conversation has become unwinnable, not a test for who is lying. Announcing "that's DARVO" mid-argument is both unfalsifiable and, to a bystander, indistinguishable from the pattern itself.
What to do
Return to the specific, once: what was said, when, and where the record is. Specifics resist reframing in a way that characterisations do not.
Then accept that the conversation is unlikely to resolve. The audience — not the person — is who the specifics were for, and repeating them past that point achieves nothing except making the exchange longer.
