This study—Neural Correlates of People’s Hypercorrection of Their False Beliefs—supports the contention that FIML practice can produce deep, wide-ranging, and enduring changes within the brain/mind of practitioners.
The basic finding of the study is:
Despite the intuition that strongly held beliefs are particularly difficult to change, the data on error correction indicate that general information errors that people commit with a high degree of belief are especially easy to correct. (Emphasis added.)
According to the study, this happens due to:
…enhanced attention and encoding that results from a metacognitive mismatch between the person’s confidence in their responses and the true answer.
This is exactly what happens when a FIML query shows the questioner that his/her assumptions about what their partner’s thoughts or intentions were were wrong.
Initially, FIML partners may experience some embarrassment or disbelief at being wrong. But since FIML queries are generally based on negative impressions, after some practice being shown to be wrong will typically produce feelings of relief and even delight.
A FIML query will generally arise out of a state of “enhanced attention” and usually further increase it by being spoken about. Incidentally, this is probably the most difficult aspect of FIML practice—controlling the emotions that accompany enhanced attention, especially when that attention concerns our own emotional reactions.
With continued practice of FIML, however, even strongly held erroneous interpersonal beliefs will be fairly easily corrected whenever they are discovered during a FIML discussion. Correcting core false beliefs (mistaken interpretations) has a wide-ranging, beneficial effect on all aspects of a person’s life.
Since the hypercorrection effect discussed in the linked study only occurs during moments of enhanced attention, the FIML technique of focusing quickly on good data agreed upon by both partners can be seen as a way of inducing states of enhanced attention that will lead to deep changes in both partners. This technique (using good data) also turns the discussion from one about feelings to one about “information,” which the study finds makes errors “especially easy to correct.”
Furthermore, since FIML practice tends to deal with very small incidents, the enhanced attention FIML induces works like a laser that quickly and painlessly excises erroneous thoughts and feelings while they are still small and have not been allowed to grow into full-blown emotional reactions.
