Why Opus Exists
Most personality tests measure traits. This one measures cognitive patterns: how you perceive, decide, and relate to others. Opus helps you identify those patterns and develop them over time.
II.
What Are Cognitive Functions?
Cognitive functions are the building blocks of how your mind works. Originally described by Carl Jung, these eight mental processes shape everything from how you make decisions to how you gather information about the world.

Everyone uses all eight functions, but we each have a unique stack, a hierarchy that determines which functions feel most natural and which require more conscious effort to access.
III.
Where Opus Comes From
This assessment is grounded in the work of Swiss psychiatrist Carl Jung, who introduced the idea that people differ in predictable ways in how they perceive and evaluate the world.
Fig. 2, Carl Jung (1875–1961), Swiss psychiatrist and author of Psychological Types (1921), whose theory forms the foundation of the cognitive function framework.
Later researchers expanded his theory into what is now known as the cognitive function model — a framework that describes patterns of perception and decision-making.
This test draws from that tradition to identify your dominant cognitive preferences.

Why Understanding Type Matters
Most conflict is not about intent. It is about differences in perception and decision-making. Understanding your cognitive pattern makes those differences visible.
Without Awareness
Misread intent
Friction feels personal
Strengths clash
Differences feel confusing
With Awareness
Differences are predictable
Friction becomes understandable
Strengths complement
Communication improves
VI.
Type Is a Starting Point
Your personality type describes preference, not limitation. It reflects your natural tendencies, not your potential.
Everyone uses all cognitive functions. Over time, strengths develop beyond what comes naturally. The goal is not to fit into a label, but to understand your starting point and grow from it.
