A cognitive bias test built on validated psychometric scales
Not a quiz about bias names. A validated psychometric assessment measuring your actual cognitive patterns — dogmatism, intellectual humility, just world beliefs, and more.
Real measurement, not trivia
Most 'cognitive bias tests' online are quizzes that check whether you can name biases like anchoring or confirmation bias. That tests vocabulary. Opinion DNA uses peer-reviewed psychometric scales to measure your actual cognitive patterns: your level of Dogmatism, your Need for Cognition (how much you enjoy effortful thinking), your Intolerance for Uncertainty, and how strongly you hold a Just World belief, the sense that people get what they deserve.
12 meta-thinking dimensions
Opinion DNA measures 12 meta-thinking elements as part of its 48-dimension assessment. These include classical cognitive pattern measures (Dogmatism, Need for Cognition, Intellectual Humility) and deeper belief structures (Teleology, Anthropomorphism, and the Primal World Beliefs). Together, they create a comprehensive map of how your mind processes information.
Part of the complete picture
Cognitive biases don't operate in isolation. Your personality traits and values interact with your thinking patterns. Opinion DNA measures all three — 48 dimensions total — and your AI-generated report analyzes how they work together. A highly open person with high dogmatism experiences a very different internal landscape than a highly open person with low dogmatism.
