An aversion to conflict seems to automatically be associated with Si/Ne types, but research like the following seems to suggest that it has more to do with your early experiences.
The excerpt below is from science of the heart, science of coherence, heart rate variability, Institute HeartMath...
Thoughts?Research has shown that the heart’s afferent neurological signals directly affect activity in the amygdala and associated nuclei, an important emotional processing center in the brain. The amygdala is the key brain center that coordinates behavioral, immunological and neuroendocrine responses to environmental threats. It also serves as the store-house of emotional memory within the brain. In assessing the environment, the amygdala compares incoming emotional signals with stored emotional memories. In this way, the amygdala makes instantaneous decisions about the threat level of incoming sensory information, and due to its extensive connections to the hypothalamus and other autonomic nervous system centers, is able to "hijack" the neural pathways activating the autonomic nervous system and emotional response before the higher brain centers receive the sensory information.
One of the functions of the amygdala is to organize what patterns become "familiar" to the brain. If the rhythm patterns generated by the heart are disordered and incoherent, especially in early life, the amygdala learns to expect disharmony as the familiar baseline; and thus we feel "at home" with incoherence, which can affect learning, creativity and emotional balance. In other words we feel "comfortable" only with internal incoherence, which in this case is really discomfort. On the basis of what has become familiar to the amygdala, the frontal cortex mediates decisions as to what constitutes appropriate behavior in any given situation. Thus, subconscious emotional memories and associated physiological patterns underlie and affect our perceptions, emotional reactions, thought processes and behavior. One of the research studies summarized in this Overview explains how we believe these emotional memory traces can be repatterned using heart-focused interventions so that coherence becomes the "familiar" and comfortable state.
