Accusation in a mirror (AiM) is a technique often used in the context of hate speech incitement, where one falsely attributes one's own motives and/or intentions to one's adversaries. It has been cited, along with dehumanization, as one of the indirect or cloaked forms of incitement to genocide, which has contributed to the commission of genocide, for example in the Holocaust or the Rwandan genocide. By invoking collective self-defense, accusation in a mirror is used to justify genocide, similar to self-defense as a defense for individual homicide.

Incitement to genocide is a crime under international law which prohibits inciting (encouraging) the commission of genocide. An extreme form of hate speech, incitement to genocide is an inchoate offense and is theoretically subject to prosecution even if genocide does not occur, although charges have never been brought in an international court without mass violence having occurred. "Direct and public incitement to commit genocide" was forbidden by the Genocide Convention in 1948. Incitement to genocide is often cloaked in metaphor and euphemism and may take many forms beyond direct advocacy, including dehumanization and accusation in a mirror.
