Part of the Casswiki article series Politics and pathocracy
In political and intelligence discourse, this means that an event cannot conclusively be traced to the party who ordered it. The event may be a coup, assassination, cover-up or the like, committed by some middleman or proxy.
Even if a connection can later be demonstrated, the public may still resist the information because the original lie is more plausible, i.e. better fits their pre-existing ideas of how things should be.
For example, maintaining plausible deniability is important when mounting a false flag operation. Such a thing is for example an attack on one’s own people, blamed on one’s enemy of choice, for the purpose of justifying aggression.
