Memory reconsolidation is something that science has proved in 2004 by Daniela Schiller.
It is ground breaking because it is about being able to erase emotional learnings by creating a mismatch experience to the problem schema.
A schema is the cognitive map a person has of reality. The way the world is viewed.
By offering the brain an experience that comprehensively mismatches the symptom belief causes the symptom belief to become updated like software on a smart phone. This is the brains innate ability to learn after being given contrary information in a sensory rich, comprehensive way.
