Computational psychiatry is a fairly new field that
…seeks to characterize mental dysfunction in terms of aberrant computations over multiple scales….
….Aberrant decision-making is central to the majority of psychiatric conditions and this provides a unique opportunity for progress. It is the computational revolution in cognitive neuroscience that underpins this opportunity and argues strongly for the application of computational approaches to psychiatry. This is the basis of computational psychiatry. (source)
One important computation that I believe is missing from our current understanding of human cognition is the high rate of interpersonal communication error.
Interpersonal communication error is especially significant psychologically because so much of human psychology is based on and grows out of interpersonal communication.
If we are making a lot of mistakes when we communicate with friends, family, spouses, and so forth, it follows that our psychological make-up will be burdened with errors that contribute to mental illness and poor functionality overall.
My considered guess is that most people make several serious mistakes in speaking or listening every hour.
In normal interpersonal conversation, most people mishear, misspeak, misinterpret, or misunderstand several times per hour.
These mistakes can be very serious. Often they snowball to produce strong emotional reactions that have no basis in fact.
The day will surely come when we will have technology that measures mistakes in communication. Before then, we have to use special techniques to find and correct communication mistakes.
Firstly, we have to recognize that such mistakes are common. Secondly, we have to understand that even a single small mistake can cause big problems. Thirdly, we need a technique to find and correct our mistakes.
FIML or something very similar to it is the technique we have available today. FIML is based on the idea that communication mistakes are common, serious, and have very significant psychological ramifications.
Over time, FIML practice completely changes the way we view communication, self, and other.
