Through real-time inquiries during real moments of real life, FIML reveals the tools and thought processes of the engineer, as they are being used.
As the receiver of a FIML inquiry, you are asked to reflect on the moments just passing.
Your answer provides a lot of information to both you and your partner.
Your partner also has information and insights into what their mind was doing, how it was modeling you and planning a response.
These shared insights are the practical details of your psychologies as they are actually functioning in a real situation.
It is transformative to see these details often.
To do this, I think you have to use a method like FIML because FIML has no presuppositions. FIML does not ask you to believe anything; just do the method.
