You seem to be referring to the SXIs' fairly rigid sets of standards, to which they compare everything and everyone; in that sense, it's a projection but it's often one that only the SXI observer can sense. Si-subtypes tend to engage others much less than normal SXIs and seem more defensive and intransigent, which can make them rather opaque to others - and themselves. Reactionary SXIs build their walls so high and stand so close to them that they can lose all perspective.....
