When I use the phrase "personal reality", I am referring to the Catholic Christian understanding that persons are ends in themselves, that is, the only creature, man, whom God created for its own sake (CCC #356). Persons are not ideas or materials for utilization. They can freely cooperate in a given system, as in free market capitalism, and freely respond in faith to God, but they are not systems in themselves to be coerced into action or strictly used for production. Despite the speculative accuracy of Meyers Briggs testing, a person is not a machine to be relied on for utilization in a given specialization. In theory, persons are free and largely unpredictable.
That said, systems are necessary for upholding the common good of persons: economically, socially, and so on. Were there not an agreed upon economic approach for upholding the common good of man, entropy would reign. Capitalism, for example, is the most successful system of economic exchange available to man to date, because all of the others distort the freedom of persons and personal reality. Nevertheless, Capitalism does have its shortcomings, and as an ideology, can prove to severly distort the worldview of its adherents. Likewise, as with any other system--including ecclesial--when taken as ideology can severely distort the worldview of its adherents.
In "Centesimus Annus", JPII argues that Catholic Christianity is not an ideology. In his work "Letter from Poland:Faith is not Ideology", Maciej Zieba O.P. makes constant reference to "Centesimus Annus" and outlines this list of Ideology's red-flags:
(1) it contains a conception of truth and goodness
