Being able to do FIML means that you have developed a skill or trait that did not exist in you before. The ability to do FIML is a functional “state of mind” that emerges from other states of mind—from consciousness, awareness, self-reflection, self-criticism, communication, language use, emotion, etc.
Doing FIML will change the way you communicate, especially with your FIML partner. It will change the way you view language and its uses.
Since FIML depends on real data agreed upon by both partners and since FIML can convincingly change how we perceive ourselves and our partners, it can give us new perspectives on psychology and/or any activity that depends on language/communication.
