By seamlessly conflating the terms “collusion” and “conspiracy,” and absolving President Trump of both, Mr. Barr revealed that the Russian information warfare technique of “reflexive control” has officially entered American public discourse — and threatens, with his recent allegations of campaign “spying,” to stay there for a while.

Reflexive control is a “uniquely Russian” technique of psychological manipulation through disinformation. The idea is to feed your adversary a set of assumptions that will produce a predictable response: That response, in turn, furthers a goal that advances your interests. By luring your opponent into agreeing with your initial assumptions, you can control the narrative, and ultimate outcome, in your favor. Best of all, the outcome is one in which your adversary has voluntarily acceded. This is exactly what has happened with much of the American public in the course of Mueller’s investigation.
